CHAPTER 2: Introduction  
2. Introduction  
The Ultra2 LVD SCSI Host Adapter (our product code IC515C) is a high-  
performance Ultra2 SCSI (Low Voltage Differential) PCI-busmastering adapter  
that functions as the interface between a SCSI bus and a PC’s PCI local bus. The  
Adapter supports all kinds of peripherals compatible with SCSI-1, SCSI-2, Fast  
SCSI, Ultra SCSI, or Ultra2 SCSI (LVD), including I/O devices such as SCSI  
scanners and storage media such as hard-disk, CD-ROM, MO, tape, and removable  
drives.  
2.1 Features  
• PCI 2.1 compliance. The Adapter meets all the latest electrical, mechanical,  
and protocol specifications for the PCI bus.  
• Full SCSI compliance. The Adapter is fully Ultra2 SCSI compliant, supporting  
advanced features such as tag queueing, sync/async transfers, and  
disconnect/reselect arbitration.  
• Plug-and-Play support. The Adapter’s onboard ROMs can handle installation,  
configuration, and booting without requiring user intervention.  
• Use of only one system IRQ. The Adapter doesn’t hog your system’s limited  
resources.  
• 32-bit data transfers between the Adapter and the host PC at up to  
133 megabytes per second in PCI burst mode. The PCI bus is a 32-bit bus;  
when it runs synchronously at 33 MHz, the Adapter achieves a peak sustainable  
operating speed of 133 MB per second.  
• Regular (synchronous) SCSI data rates up to 80 megabytes per second, and  
asynchronous SCSI data rates up to 10 megabytes per second.  
• Compatible with all types of standard SCSI peripherals. Hard drives, CD-ROM  
drives, tape drives, printers, scanners—it doesn’t matter what types of periph-  
erals you want to hook to the Adapter. As long as they’re compliant with Ultra2  
SCSI (LVD), Ultra SCSI, Fast SCSI, SCSI-2, or SCSI-1, they should work.  
®
• Support for hard-drive capacities up to 8 GB. With the Adapter, MS-DOS  
hard-disk limitations can be extended from 1 GB to 8 GB.

ULTRA2 LVD SCSI HOST ADAPTER  
• User-hardwirable, user-programmable, or automatic SCSI termination. You  
can choose between hardwire-enabling termination on the Adapter,  
programming the termation through its firmware, or letting the Adapter  
handle termination automatically, eliminating the need to open up the PC  
every time you need to make termination changes.  
®
• Onboard BIOS supports Microsoft MS-DOS. The Adapter has the necessary  
software onboard to handle MS-DOS disk-drive operations without requiring  
additional system-based drivers.  
• Support for all other major operating systems. The Adapter includes drivers  
®
®
®
®
®
for Windows 98, Windows 95, Windows NT, IBM OS/2 , Novell NetWare ,  
®
®
®
®
SCO UNIX , SCO UnixWare , and Linux .  
• SmartSCSI™ Setup Utility program. You can use this firmware utility to  
customize the Adapter’s configuration. Unless you need to hardwire  
termination, you don’t have to set any jumpers at all.  
• Built-in Integrated Scatter/Gather Engine (ISGE™). This hardware circuitry  
heightens performance in all scatter/gather operations.  
• 256-byte FIFO. The Adapter uses a 256-byte FIFO caching buffer to manage  
PCI-to-SCSI-bus structure timing for data and command transfer.  
• Command queueing. With this special feature, the Adapter can process as  
many as 255 simultaneous SCSI commands.  
NOTE  
The README.TXT file on Driver Disk 1 might contain updates,  
corrections, and additions to the information in this manual. However, if  
you consult this file, you need to keep in mind that it was written by the  
company that developed the drivers for use with the Ultra2 LVD SCSI  
Host Adapter, and they use their own “INI-®A100U2W” code (rather than  
“IC515C”) to refer to the Adapter.

CHAPTER 2: Introduction  
2.2 The Adapter Illustrated  
The Ultra2 LVD SCSI Host Adapter and its major components are shown in  
Figure 2-1 below. You might want to refer to this diagram as you install your  
Adapter (see Chapter 4). Figure 2-2 below that shows closeups of the Adapter’s two  
SCSI connectors. The Adapter’s other components include:  
• Jumper JP1: These posts are usually left open so that termination can be  
firmware-controlled. Put a jumper on them to hard-wire termination always  
ON.  
•
SE LED: Lights if any single-ended (legacy) devices are attached to the Adapter.  
• LVD LED: Lights if any Ultra2 LVD SCSI devices are attached to the Adapter.  
• ACT LED: Dark if the attached SCSI bus is passively terminated (which we  
don’t recommend); lights if the bus is actively terminated (including forced-  
perfect termination).

ULTRA2 LVD SCSI HOST ADAPTER  
3. Before You Install: Getting Started  
3.1 The Adapter and the SCSI Bus  
Your Ultra2 LVD SCSI Host Adapter performs busmastering and works with the  
host computer to provide a means of control for the SCSI bus. By daisychaining  
peripheral devices together, as many as fifteen devices can be linked to the Adapter  
on the SCSI bus. The Adapter does not have to be placed in any particular physical  
position on the bus, but because it doesn’t have two external connectors, it has to  
be at the end of any all-external bus.  
SCSI devices communicate on the bus using bus arbitration, which gives each  
device an opportunity to use the bus based on the device’s priority (which is  
determined by the device’s ID, not its physical location). The Adapter is factory-  
preset to ID 7, the ideal ID for it on a single-adapter bus (see the next section).  
3.2 SCSI ID Numbers  
Each internal or external device attached to the Ultra2 LVD SCSI Host Adapter, as  
well as the Adapter itself, must have a unique SCSI ID number. This SCSI ID  
determines priority when two or more devices are trying to use the SCSI bus at the  
same time. No two devices can have the same ID; the SCSI ID uniquely defines the  
device to the SCSI bus.  
The Ultra2 LVD SCSI Host Adapter is factory-preset to use SCSI ID 7, which  
gives it the highest priority on the SCSI bus; this ID number should not be  
changed. IDs are usually assigned to each peripheral device at the factory, but you  
will be able to set them to whatever you need them to be. This is usually done with  
jumpers, DIP switches, or other physical controls; refer to each peripheral’s  
documentation to determine how to set its ID. The key thing to remember is that  
no two devices on the same SCSI bus can have the same ID; each ID must uniquely  
identify a single device. Also keep in mind that a device’s SCSI ID does not  
necessarily have any relationship to its physical location or its position on the bus.  
For example, you can have an internal SCSI peripheral with ID 0, and an external  
SCSI peripheral with ID 6. (Gaps in the number sequence don’t matter either.)

CHAPTER 3: Before You Install: Getting Started  
A device’s ID number will reflect the priority it has on the SCSI bus; except for  
ID 7 (reserved for host adapters), the lower a device’s number, the higher its  
priority. So you should assign lower numbers to the devices that you will need to  
access more frequently or at a moment’s notice, and higher numbers to less critical  
devices. (8-bit “Narrow” SCSI peripherals must use SCSI IDs 0 through 6; 16-bit  
“Wide” peripherals can be assigned IDs 8 through 15 as well.) Here’s an example  
setup:

:
Primary hard drive  
Secondary hard drive  
CD-R drive  
DVD drive  
Floppy drive  
Tape drive  
SCSI scanner  
SCSI host adapter  
:
15  
(Other, low-priority SCSI peripherals)  
When you assign SCSI IDs, we recommend that you leave the Ultra2 LVD SCSI  
Host Adapter set for ID 7, its factory-default setting; use the Adapter’s firmware  
configuration utility if you must change the ID number (see Section 4.6.4). If you  
plan to boot your system from a SCSI hard-disk drive, set that drive to ID 0 for best  
operation with most operating systems. (Most hard drives come from the factory  
preset to ID 0.) Set the second hard drive, if you’re using one, to ID 1, and set  
additional peripherals to sequentially higher IDs.  
You can use the Windows 95 or 98 Device Manager to view the SCSI ID (and  
other system-configuration parameters) assigned to each SCSI device attached to a  
Windows 95 or 98 PC. You can do the same thing through just about any operating  
system by accessing the Adapter’s SmartSCSI utility.

ULTRA2 LVD SCSI HOST ADAPTER  
3.3 SCSI-Bus Length  
Because of its inherent electrical vulnerability as a high-speed parallel interface,  
the SCSI bus has definite distance limitations. With earlier versions of the SCSI  
interface, the maximum length of the bus—the total distance from the terminated  
device at one end to the terminated device at the other end—were normally  
inversely proportional to the data rate, as shown below:  
Max. Length  
Standard  
6 m (19.7 ft.)  
6 m (19.7 ft.)  
3 m (9.8 ft.)  
SCSI-1  
Fast SCSI (SCSI-2)  
Ultra SCSI (SCSI-3), up to 4 devices  
1.5 m (4.9 ft.) Ultra SCSI (SCSI-3), up to 7 devices (narrow) or 15 devices (wide)  
Ultra2 SCSI, however, can be extended to distances as great as 12 m (39.4 ft.) with  
the proper cabling, as long as all of the devices are Ultra2 compliant, or even as far  
as 25 m (82 ft.) to a single Ultra2 device. (If any attached devices are not Ultra2  
compliant, the bus speed drops to that of the slowest SCSI interface represented by  
a device on the bus, and the maximum distance drops to that of the most length-  
restricted SCSI interface represented by a device on the bus.) Remember that if  
you attach both internal and external devices to the Adapter, the bus goes from the  
last internal device to the last external device. To make sure you can run the  
greatest possible distance, make sure to use cable with impedance of at least  
120 ohms (do not use 90-ohm cable unless all of the devices you’re attaching are  
non-Ultra2 LVD type); use high-quality twisted-pair cable with high-quality shielded  
connectors for your external cable.  
3.4 SCSI-Bus Termination  
To ensure reliable communication, the SCSI bus must be properly “terminated.”  
That is, the bus must be bracketed with networks of electrical resistors called  
“terminators” that absorb the remains of data signals and prevent them from  
echoing and interfering with fresh signals. Unless they are actually built into the  
cables, terminators must be placed—or enabled, if the last devices have them built  
in—at the two extreme ends of the SCSI bus. All devices that lie between the ends  
must have their terminators removed or disabled. SCSI cabling is designed to be  
connected in daisychain fashion, with no device on the bus being directly  
connected to more than two others. No branching is permitted on the SCSI bus.  
Refer to the example setups in Figure 3-1 on the next page.

ULTRA2 LVD SCSI HOST ADAPTER  
Because the methods for terminating SCSI peripherals can vary widely, you should  
refer to a given peripheral’s documentation for instructions on how to enable or  
disable its termination. Here are some general tips about device termination,  
though:  
• Internal Ultra2 SCSI peripherals are shipped from the factory with termination  
disabled; this setting cannot be changed. Proper termination for internal  
Ultra2 peripherals is always provided by a built-in connector at the end of the  
attached internal Ultra2 SCSI cable.  
• On other kinds of internal SCSI peripherals, termination is usually controlled  
by manually setting a jumper or moving a switch on the unit, or by physically  
installing or removing one or more resistor modules on the unit.  
• On external SCSI peripherals of all kinds, termination is usually controlled by  
installing or removing a SCSI terminator, although some peripherals have  
internal termination that you can switch on or off instead.  
• Most non-Ultra2 SCSI peripherals come from the factory with termination  
enabled.  
As it is shipped from the factory, your Ultra2 LVD SCSI Host Adapter can  
automatically enable or disable its built-in termination. If the Adapter senses that it  
is at the end of the bus—for example, if you attach only internal or only external  
SCSI devices to it—it will auto-terminate itself. If it senses that it is in the middle of  
the bus—for example, if you attach both internal and external SCSI devices to it—  
it will auto-disable its terminators.  
If you would rather set the Adapter’s termination manually, you can go into the  
SmartSCSI™ Setup Utility in the Adapter’s firmware (see Section 4.6.4) and  
change the “SCSI Terminators” setting in the “Adapter Setup” menu. Switch from  
“Automatic” to either “ON” (always ON), “OFF” (always OFF), or a combination of  
“High bit ON”/“OFF” and “Low bit ON”/“OFF”:  
• Set the high bit and low bit both ON if the Adapter is at the end of the bus, so  
that only external devices or only internal devices are attached.  
•
Set the high bit and low bit both OFF if the Adapter is in the middle of the bus,  
so that both internal and external devices are attached, and if at least one device  
on each side (internal and external) is a Wide SCSI (68-pin, 16-bit) device.  
• Set the high bit ON and the low bit OFF if the Adapter is in the middle of the  
bus, so that both internal and external devices are attached, and if all of the  
devices on either or both sides (internal and external) are Narrow SCSI  
(50-pin, 8-bit) devices.

CHAPTER 3: Before You Install: Getting Started  
NOTE  
If you mix Wide and Narrow devices on the same side (internal or  
external) of a SCSI bus attached to the Adapter, we strongly recommend  
that all of the Narrow devices be attached to the bus closer to the  
Adapter than all of the Wide devices. If you attach any Narrow devices at  
the far end of the bus, beyond any Wide devices, you’ll have to be very  
careful to terminate the Wide lines (Pins 51 to 68) of the last Wide device.  
Alternatively, you can “hardwire” the Adapter so that termination is always ON by  
installing jumpers on the Adapter’s circuit board. The most common application  
for which you would hardwire-enable termination is this: installing multiple  
Adapters in multiple PCs, but attaching them to the same bus in order to share  
peripherals. In such situations, you might want to hardwire termination ON for any  
Adapters that are on the end of the bus, so that you can turn off the computers in  
which those Adapters are installed without losing termination power and disabling  
the SCSI bus. If for this (or whatever) reason you do want to hardwire termination  
ON, you need to install a jumper on the Adapter before you put it in your PC.  
(Once this jumper is installed, it will override the termination setting in the  
Adapter’s firmware.) The jumper should be installed at location JP1, as shown in  
Figure 3-3 below.

ULTRA2 LVD SCSI HOST ADAPTER  
3.5 Attaching Legacy Equipment  
Your Ultra2 LVD SCSI Host Adapter supports legacy (non-Ultra2) peripheral  
devices. However, we recommend that you attach only Ultra2 LVD devices to the  
Adapter. This is because, if you do attach any other type of SCSI device, the bus will  
become limited to (a) the speed of the slowest device and (b) the length supported  
by the least distance-tolerant device.  
3.6 The Complete Package  
Your complete Ultra2 LVD SCSI Host Adapter package includes the following:  
• The Adapter card itself.  
• A 125-cm (4.1-ft.) 68-pin internal “Wide SCSI” ribbon cable.  
• Two diskettes containing driver software.  
• This manual.  
If anything is missing, contact Black Box right away. If the package has been  
damaged, contact both Black Box and the shipping carrier.

CHAPTER 4: Installation and Configuration  
4. Installation and Configuration  
This chapter describes how to install and configure your Ultra2 LVD SCSI Host  
Adapter. (If you are installing multiple Adapters in a clustered system, refer to  
Section 4.5.) If you have any difficulty, please refer to Section 6.1.  
4.1 Installing the Adapter Itself  
Follow these instructions to install your Ultra2 LVD SCSI Host Adapter:  
NOTE  
If you’re running Windows NT on the computer you’ll be installing the  
Adapter in, you might want to install the driver before you install  
hardware. If so, follow the procedure listed in Section 5.4.  
1. Turn OFF your computer, unplug it, and disconnect it from all other devices.  
2. Take precautions to keep from damaging the Adapter with any accidental  
static discharge. At the very least, discharge yourself on a metal part of the PC  
chassis or on some other metallic surface before touching the Adapter. If  
possible, stand on an anti-static mat and wear a grounding strap or anti-static  
gloves.  
3. (Optional) If you need to hardwire termination on the Adapter so that it’s  
always enabled (ON), install the necessary jumper(s) on the Adapter if you  
haven’t done so already. See Section 3.4.  
4. Remove the cover from the computer case.  
5. Locate an unused 32-bit PCI expansion slot (the slot must support  
busmastered data transfers). PCI slots are shorter than ISA or EISA slots and  
are typically white. Usually there are several of them on the motherboard.  
(One of these might be a shared slot into which you can insert either an  
ISA/EISA board or a PCI board.) Refer to your PC’s documentation if you’re  
still not sure which ones are the PCI slots.  
Once you’ve located a PCI slot, unscrew and remove the metal bracket  
that covers the card-slot opening. (Save the screw; you will be using it to  
secure the host adapter in your computer.)

6. Holding the SCSI Host Adapter by the mounting bracket and card edge, with  
it oriented so that the external connectors are facing the right way, insert the  
Adapter in the PCI slot. Press it down firmly so the contacts are securely  
seated in the slot. See Figure 4-1 on the next page.  
CAUTION!  
Though the PCI connector is keyed to prevent cards like the Adapter  
from being inserted incorrectly, it is possible to damage the Adapter by  
forcing it into other types of connectors.  
Figure 4-1. Inserting the Adapter in a PCI slot.  
7. When the Adapter is firmly seated, secure its metal bracket to the PC’s chassis  
with the screw you removed in step 3.  
8. (Optional) Most computers have one or more hard-drive-activity LEDs on  
their front panel. If you want to, you can use your own cabling (because we do  
not include cables for this purpose) to attach one of these indicators to the  
Adapter’s four-pin LED connector, J3 (see Figure 3-2 on page 19 and  
Figure 4-2 on the next page). Once you do so, the LED will light whenever  
there is activity involving the attached Adapter anywhere on the SCSI bus.

9. Most PCI-bus computers will automatically assign the Adapter an I/O address,  
IRQ channel, and BIOS address. If this is not the case with your system, you’ll  
have to do this manually, either by setting jumpers on the PC’s motherboard  
(which you can do now; refer to your PC’s documentation) or changing the  
settings of the PC’s CMOS BIOS (you’ll have to do this later—see  
Section 4.3). (If the PC will be booting from a SCSI drive attached to the  
Adapter, you might also need to change the drive-type setting in the PC’s  
BIOS, because it might be expecting the boot drive to be an IDE drive.)  
10. If you are attaching any internal SCSI devices to the Adapter, go on to  
Section 4.2. Otherwise, replace the PC’s cover, reconnect all devices,  
plug the PC back in, and go on to Section 4.3.

ULTRA2 LVD SCSI HOST ADAPTER  
4.2 Attaching Other SCSI Devices to the Adapter’s Bus  
You can connect as many as fifteen internal and external SCSI devices to your  
Ultra2 LVD SCSI Host Adapter. Follow the directions listed in this section. (If you  
are connecting SCSI devices to multiple Adapters to form a clustered system, refer  
to Section 4.5.)  
4.2.1 CONNECTING INTERNAL SCSI DEVICES  
If you are connecting internal SCSI devices, make sure to use a SCSI ribbon cable  
that (a) is not too long (see Section 3.3), (b) has the appropriate characteristics  
(see Section 3.3), and (c) has enough connectors to accommodate the Adapter  
and all of your internal peripherals. Figure 4-3 below shows the preterminated  
Wide (68-pin) internal cable that comes with the Adapter; it has enough  
connectors for four internal SCSI devices.

Figure 4-3. The Adapter’s included internal ribbon cable.  
This cable is 125 cm (4.1 ft.) long; whether you use it or some other cable, keep  
in mind that the total length of cable on the Adapter’s SCSI bus, including both  
internal and external cables, mustn’t exceed 12 m (39.4 ft.) unless you’re attaching  
one and only one peripheral, in which case you can run as far as 25 m (82 ft.). And  
this assumes that all of your devices are Ultra2 SCSI LVD compliant; if you are  
attaching any legacy devices, the maximum total bus length will be much less:  
• 6 m (19.7 ft.) if the only legacy devices attached to the bus are SCSI-1 or Fast  
SCSI (SCSI-2) devices.  
• 3 m (9.8 ft.) if you have four or fewer devices attached to the bus and any of  
them are Ultra SCSI (SCSI-3) devices.  
• 1.5 m (4.9 ft.) if you have five or more devices attached to the bus and any of  
them are Ultra SCSI (SCSI-3) devices.  
The cable should have an impedance of at least 120 8 ohms if any Ultra2 SCSI  
LVD devices are attached; the impedance can be as low as 90 8 ohms only if all  
attached devices are non-Ultra2-type.

CHAPTER 4: Installation and Configuration  
Take these steps to connect internal SCSI devices to the Adapter:  
1. If you haven’t already done so, turn OFF and unplug the PC, disconnect all  
other devices from it, and remove its cover.  
2. If you haven’t already done so, prepare each internal SCSI peripheral for  
installation: configure the device’s SCSI ID and termination. (If you’ll be using  
the included cable, or some other preterminated cable, all of the devices  
should have termination turned OFF. If you’ll be using a non-terminated  
cable, turn the last device’s termination ON and leave the others OFF.) For  
instructions, see the device’s documentation as well as Sections 3.2 and 3.3.  
3. Install each internal SCSI peripheral in your computer. Refer to your  
computer’s and peripherals’ documentation for instructions.  
4. Plug one end of your internal SCSI cable into the Adapter’s appropriate  
internal SCSI connector. (If you’re using the cable included with the Adapter,  
plug in the unterminated end.) Make sure the colored stripe that runs the  
length of one edge of the cable is aligned with Pin 1 of the Adapter’s  
connector. The cable should be keyed for proper insertion. Figure 4-4 below  
shows how to plug in this cable.  
SCSI Ribbon Cable  
Internal Connector  
(68-Pin Micro D68)  
Figure 4-4. Plugging a narrow internal cable into the Adapter.  
5. Plug the internal cable’s other connectors into the internal SCSI peripherals  
that you installed in step 3. (If you are using the cable included with the  
adapter, or some other cable with 68-pin connectors, and any of the  
peripherals are Narrow [50-pin] devices, you will need to attach 50-pin-  
female-to-68-pin-female adapters, such as our product code EVNSCT38,  
between the cable and the device.) Also attach internal power cables to any of  
these devices that get their power from the PC. Refer to the instructions for  
doing these things in the peripherals’ documentation. Remember to  
terminate the last internal device.

ULTRA2 LVD SCSI HOST ADAPTER  
6. Inspect your internal cabling one last time to make sure it is attached  
correctly everywhere, then replace the PC’s cover. If you are attaching any  
external SCSI devices to the Adapter, go on to Section 4.2.2; otherwise,  
reconnect all external devices to the PC and plug the PC back in.  
4.2.2 CONNECTING EXTERNAL SCSI DEVICES  
If you are connecting external SCSI devices, make sure that (a) you have enough  
external SCSI cables to accomodate all of your devices (the Adapter does not come  
with any external cables), (b) the total length of the cables is not too great, and  
(c) the cables have the appropriate characteristics (see Sections 3.3 and 4.2.1).  
If your external devices have micro D68 connectors like the Adapter itself does,  
you can use our External Ultra2 LVD SCSI Cable (product code EVMS25).  
1. Prepare each external SCSI peripheral for installation: configure the device’s  
SCSI ID and termination (terminate the last external device attached to the  
bus). For instructions, see the device’s documentation as well as Sections 3.2  
through 3.4.  
2. Plug the connector at one end of the first external SCSI cable into the  
Adapter’s external SCSI connector. These connectors will be keyed for proper  
cable insertion.  
3. Plug the connector at the other end of the external SCSI cable into one of  
the SCSI connectors on the first external SCSI peripheral, following the  
instructions for doing this in the peripheral’s documentation.  
4. To connect other external SCSI devices, use additional external SCSI cables  
to daisychain each device to the previous device until all external SCSI devices  
have been connected, as described in the peripherals’ documentation and as  
shown in Figure 4-5 on the next page (refer to the peripherals’ documentation  
for more information). Remember to terminate the last external device.  
5. Reconnect all external devices to the PC and plug the PC back in.

4.3 Initial Startup  
Once you’ve installed your Ultra2 LVD SCSI Host Adapter and its associated  
devices, power up its host computer system and all external devices. Interrupt the  
normal bootup process at this point if you need to change the settings of the PC’s  
CMOS BIOS in order to assign the Adapter an I/O address, IRQ channel, and/or  
BIOS address, or if you need to change the drive-type setting for the boot disk (see  
step 9 in Section 4.1; if you need to do this, reboot when you’re finished). During  
the boot process, watch for these things to be displayed (although this list might  
vary depending on the design of your system’s BIOS):  
• The normal power-on self-test and memory test.  
• A sign-on message from the Adapter, followed by a list of attached SCSI  
peripheral devices.  
Make sure that the self-test and memory test look okay, and make sure that  
the Adapter’s list of attached devices is correct. If everything checks out, your  
computer system should be ready for initial configuration (including, as is  
necessary in some situations, low-level hard-disk formatting to initialize drives);  
go on to Section 4.4, then Section 4.6.

ULTRA2 LVD SCSI HOST ADAPTER  
4.4.1 WHY YOU NEED TO  
DO  
THIS  
A new SCSI disk drive is normally low-level formatted at the factory to simplify  
installation. Every SCSI hard-disk drive must be physically low-level formatted,  
partitioned, and logically formatted before it can be used to store data. SCSI hard  
disks are physically low-level formatted at the factory and do not usually need to be  
formatted again. (If you do need to low-level format a disk, see Section 4.4.2.)  
Howevere, if you connect a new SCSI hard-disk drive to your Ultra2 LVD SCSI  
Host Adapter, you must partition and logically format the drive. For DOS,  
Windows 3.x***?, Windows 95, and Windows 98, use the DOS commands FDISK  
and FORMAT to do this (refer to the documentation for your PC, your hard drive,  
DOS, and—if necessary—Windows). For other operating systems, refer to the  
operating system’s documentation for instructions.  
If you are booting from a SCSI hard-disk drive, make sure the “Hard Disk” or  
“Hard Drives” setting in your PC’s CMOS program is set to “None” or “No Drives  
Installed,” as is required for SCSI hard drives. See your PC’s documentation for  
details.  
If you’ve installed both SCSI and non-SCSI (IDE, for example) disk drives, the  
non-SCSI drive is typically the boot drive. But if your computer supports the BBS  
(BIOS Boot Specification), not only can both SCSI and non-SCSI drives coexist,  
you can specify which drive to boot from. See your PC’s documentation for more  
details.  
4.4.2 LOW-LEVEL FORMATTING  
A low-level format will erase any data that is stored on the target disk. Before  
attempting to perform a low-level format, make sure the data on the target disk has  
been backed up. You can do a low-level format with the Ultra2 LVD SCSI Host  
Adapter’s SmartSCSI Setup Utility; see Section 4.6.6.  
The low-level format sets the media to a state which is easily recognized by the  
host adapter on the SCSI bus. Once this format is completed, you will need to  
partition the drive. Refer to your operating system’s documentation for further  
information on partitioning drives.

CHAPTER 4: Installation and Configuration  
4.5 Multiple Initiators and Clustering  
A multiple-initiator environment is one in which the SCSI bus has two or more host  
adapters. To work in a cluster, the host adapters must perform properly in such an  
environment—by not resetting the bus without an explicit host command, for  
example. Our Ultra2 LVD SCSI Host Adapters are built for multi-initiator  
operation and adhere strictly to the SCSI standard.  
Figure 4-6 on the next page illustrates the principal components in a cluster’s  
I/O system. It shows a simple cluster with two servers sharing access to online  
storage (the basic model for Microsoft’s MSCS clusters). Both servers contain an  
host adapter that provides access to the shared extemal I/O bus. Servers can share  
disks or arrays attached to this bus. The operating system controls contention for  
disk access by either resolving access conflicts with a component called a  
distributed lock manager (DLM) or using a so-called “shared-nothing” model that  
partitions disks and arrays, giving each server control over a subset of the storage  
under normal circumstances. MSCS uses the shared-nothing approach.  
In such applications, multiple initiators can be used on a single SCSI bus. The  
bus is configured to have more than one host adapter inserted into at least two  
distinctly different computer systems sharing peripheral devices. In these  
circumstances, it is possible to have one of the two computer systems turned off.  
Under these conditions, the host adapter has a jumper that can be enabled  
(closed) to set the active on-board termination ON all the time, regardless of  
whether power is applied or not (refer to Section 3.4). The host adapter is shipped  
without the jumper installed, and this setting need not be changed in most cases.  
Before operating such a system, visually inspect the configuration you have  
installed to verify that all cables have been inserted correctly.

4.6 The Setup Utility  
4.6.1 THE BOOT OPTIONS, SELECT CHANNEL MENU, AND MAIN MENU  
Among the Ultra2 LVD SCSI Host Adapter’s built-in firmware programs is a menu-  
driven SCSI Setup Utility, with which you can change the Adapter’s settings without  
opening the computer or handling the Adapter’s circuit board. (Note that the  
Adapter’s default settings are appropriate for most PCI systems, so odds are you  
won’t need to run the Utility.) To start the Utility, first make sure that all of the  
devices attached to the SCSI bus are powered up when the host computer system is  
turned ON. Then reboot the PC the Adapter is installed in and wait for this  
prompt to appear (it will be preceded by version and copyright info):  
!!! Press < Ctrl > < I > for SmartSCSI Setup Utility !!!  
!!! Press < Ctrl > < B > to boot from SCSI CD-ROM !!!  
!!! Press < ESC > to continue !!!

CHAPTER 4: Installation and Configuration  
When you see this prompt, you can either:  
• Wait five seconds or press [ESC] to continue with the boot process;  
• Press [CTRL] [B] to boot from a SCSI CD-ROM attached to the Adapter  
(if this capability has been firmware-enabled—see Section 4.6.5); or  
• Press [CTRL] [I] to start the Utility.  
The Utility’s Main Menu (shown, with Device Setup selected, in Figure 4-7  
below) appears directly as soon as you run the Utility. When it does, you will  
have five main options to choose from:  
Scan Bus Device Setup Adapter Setup BIOS Setup Disk  
Utility  
Selecting any of these options (using the right- and left-arrow keys) will cause the  
Utility to display a corresponding submenu; see Sections 4.6.2 through 4.6.6  
respectively. You can also exit the utility at any time by pressing <ESC> (Escape);  
see Section 4.6.7.

ULTRA2 LVD SCSI HOST ADAPTER  
4.6.2 THE SCAN BUS SCREEN  
If you select “Scan Bus” at the Main Menu and press ENTER, the Utility scans the  
SCSI bus and displays a screen that lists, in the order of their SCSI IDs, the devices  
it has found, as well as the IDs without any devices assigned to them. While you’re  
at this screen, you can press <ENTER> to “Execute” a new scan (to rescan the bus).  
Keep in mind that (a) the best ID for a bootable hard disk is ID 0, and  
(b) otherwise, you should only change a device’s ID if it conflicts with the ID of  
another device on the same bus (refer to the device’s documentation for how to do  
this).  
4.6.3 THE DEVICE SETUP MENU  
If you select “Device Setup” at the Main Menu and press ENTER, the Utility displays a  
screen listing all of the bus’s possible SCSI IDs and a set of attributes that you can set  
for those IDs. Use the right-, left-, up-, and down-arrow keys to select any attribute,  
the plus and minus keys to change the setting of the selected attribute, or <F8> to  
reload the factory defaults for all attributes.  
Asynchronous Transfer: Set this value to “Yes” or “No” (the factory-default  
setting is “No”) to respectively enable or disable asynchronous data transfer for the  
corresponding ID. The maximum data rate at which the Ultra2 LVD SCSI Host  
Adapter will transfer data asynchronously is 10 MB/second.  
Maximum Synchronous Transfer Rate: Set this value to the maximum sync data  
rate at which the correpsonding devices can operate. (You can press “+” and “–” to  
cycle through the possible settings.) Your Adapter will run at 80 MB/second; this is  
the factory-default setting for all SCSI IDs. Whenever you connect a new SCSI  
device to the Adapter’s bus, refer to the device’s manual to determine its actual  
maximum data rate. If you still can’t figure it out, set this value to 10.0  
(10 MB/second) until you can contact the device’s manufacturer.  
DOS Space > 1 GB: This value has to do with how information stored on SCSI  
hard drives is accessed. (It has no meaning for non-hard-drive devices.) Under the  
“No” setting, the Adapter assumes that the corresponding drive has a maximum of  
64 read/write heads and 32 sectors, a “head-mapping” configuration that conforms  
to the normal MS-DOS limit of 1024 cylinders (one gigabyte of capacity). Under  
the factory-default “Yes” setting, the Adapter assumes that the drive has a  
maximum of 255 heads and 63 sectors, an 8032-cylinder head-mapping  
configuration that corresponds to almost 8 GB of DOS-accessible capacity.

CHAPTER 4: Installation and Configuration  
CAUTION!  
If any hard drive connected to the Adapter already has data stored on it,  
changing the head mapping will corrupt or erase that data and could  
cause other unexpected problems. If you want to keep the data on a  
drive, please back it up before changing the “DOS Space > 1GB” setting,  
then delete the target drive’s existing partitions with this Setup Utility’s  
“Format” Disk Utility function or the DOS FDISK utility. Then, after you  
change this setting, you can restore and reinstall from the backup.  
All device drivers for the Adapter will support different head mappings based on  
the setting of this option:  
Under MS-DOS, OS/2, and Windows NT, we recommend the “Yes” setting for  
any hard disk whose capacity is greater than 1 GB.  
SCO UNIX does not have a 1-GB barrier, but it must know whether or not the  
boot-file system is located within the first 1024 cylinders of disk space in order to  
perform its kernel-boot routines. If your root file system is larger than 1 GB or is  
located beyond the first 1 GB of disk space, you should set "Dos Space > 1GB" to  
“Yes.” Otherwise, you can safely set it to “No” (although, to be on the safe side, we  
recommend that you set it to “Yes” anyway).  
Note that, unlike the other operating systems the Adapter supports, SCO UNIX  
cannot support having drives with different head mappings attached to the same  
bus (channel). The head mapping used on the drive with SCSI ID 0 must be used  
on all other drives attached to the same bus.  
On machines running multiple operating systems, you must use the same head  
mapping for any given hard drive across operating systems. Unless one of your oper-  
ating systems is SCO UNIX, however, different drives can have different head mappings.  
In general, we recommend that, to be on the safe side, you set “DOS Space >  
1GB” to “Yes” for any SCSI hard disk with capacity greater than 1GB.  
Spin Up Disk Drive: Set this option to “Yes” to have the SCSI Host Adapter  
initiate motor spin-up for SCSI disk drives. This way, the Adapter’s BIOS can  
conserve system power during boot-up by signaling the attached devices to start at  
delayed intervals. The factory-default setting for this option is “No.” This option  
has no effect on peripherals that are not disk drives.

ULTRA2 LVD SCSI HOST ADAPTER  
Enable Disconnect: When this option (usually referred to as “disconnect/  
reconnect”) is set to “Yes” (the factory-default setting), devices can temporarily  
disconnect from the SCSI bus to allow the Adapter to perform other functions on  
the bus. The device and the Adapter can then reconnect when the bus is needed.  
We strongly recommend that you not set this option to “No” unless the  
corresponding device is an older one that cannot support disconnect/reconnect.  
Enable Wide Negotiation: This option determines whether or not the Adapter  
will start data-transfer negotiations with the corresponding device by requesting a  
“wide SCSI” (16-bit) path. Set this option to “No” for any narrow-only device or for  
any other attached device that doesn’t seem to handle wide data transfer properly  
(as is often the case with certain older CD-ROM, recordable CD, and tape drives).  
The factory-default setting for this option is “Yes.”  
4.6.4 THE ADAPTER SETUP MENU  
If you select “Adapter Setup” at the Main Menu and press ENTER, the Utility displays  
a screen at which you can set three key options for the Ultra2 LVD SCSI Host Adapter  
itself. Use the up- and down-arrow keys to select an option, the plus and minus keys to  
change its setting, or <F8> to reload the factory-default settings for all options.  
Host Adapter SCSI ID: If necessary, you can use this option to change the  
Adapter’s ID number on the SCSI bus. The Adapter supports sixteen IDs  
numbered 0 through 15. ID 7 (the Adapter’s factory-default ID) has the highest  
boot priority (is examined first during the boot process); from there, IDs are  
examined in numeric order from 0 to 15. This means that if you have to change  
the Adapter’s ID, you should make it as low a number as possible.  
You can have multiple SCSI host adapters attached to the same SCSI bus (see  
Section 4.5); these must all have different SCSI IDs. But if you have multiple  
Adapters that are each attached to separate SCSI buses, even if they’re installed on  
the same PCI bus, you don’t have to use different SCSI IDs for the Adapters.  
SCSI Terminator: You can use this option to have the Adapter auto-terminate  
itself (“Automatic,” the factory-default setting) or—if the Adapter doesn’t seem to  
autosense the bus state properly, or if for whatever reason you would rather set  
termination yourself—set its termination always “ON” (if the Adapter is at the end  
of the bus) or “OFF” (if the Adapter is in the middle of the bus), or set the  
termination to the proper combination of “High bit ON”/“OFF” and “Low bit  
ON”/“OFF” as described in Section 3.4.

CHAPTER 4: Installation and Configuration  
SCSI Parity Check ON: You can use this option to enable or disable parity  
checking on the SCSI bus by the Adapter. The default setting for this option is  
“Yes”—if you leave it set this way, make sure that all of your peripherals on which  
parity checking can be user-enabled or -disabled have it enabled. If any of the  
devices attached to the bus don’t support parity checking, set this option to “No.”  
4.6.5 THE BIOS SETUP MENU  
If you select “BIOS Setup” at the Main Menu and press ENTER, the Utility displays  
a screen at which you can set four key options for the Ultra2 LVD SCSI Host  
Adapter’s BIOS. Again, use the up- and down-arrow keys to select an option, the plus  
and minus keys to change its setting, or <F8> to reload the factory-default settings for  
all options.  
Enable Host Adapter BIOS: Use this option to control whether the Adapter uses  
the SCSI-disk I/O routines in its BIOS. The factory-default setting for this option is  
“Yes.” If you set it to “No,” you will disable the Adapter’s ability to use the boot  
capabilities and other features of its BIOS, including all of the other features normally  
available in this menu (they will be “grayed out”). Only disable the BIOS if you want to  
use other drivers for all of the attached devices.  
Boot Device ID: You can use this option to select which SCSI device will be the  
designated boot device for the system. The factory-default device ID is “0”, which is  
the best choice for most operating systems and applications.  
BIOS Support for Bootable CD-ROM: When this option is set to “Yes,” the  
Adapter will support booting from one CD-ROM (and only one CD-ROM at any  
given time). (This option is useful if you need to install an operating system or  
other software from CD-ROM at boot-up.) The default setting for this option is  
“No.” Unless this option is set to “Yes,” pressing [CTRL] [B] at boot time to boot  
from CD-ROM (see Section 3.2.1) will have no effect.  
BIOS Treat Removable Disk as Fixed Disk: When this option is set to “Yes,” the  
Adapter’s BIOS will treat removable disks as if they were fixed disks, so you can run  
removable-disk media without needing additional (third-party) software drivers.  
(You will still need third-party drivers, however, if you need to be able to hot-swap  
removable disks while the system is operating. Hot-swapping removable disks  
without using drivers that support this function will reult in lost data and possibly  
other unexpected problems.) The default setting for this option is “No.”

4.6.6 THE DISK UTILITY MENU  
If you select “Disk Utility” at the Main Menu and press ENTER, the Utility displays  
a screen much like the Scan Bus screen (see Section 4.6.2) that lists the devices on  
the SCSI bus. Use the up- and down-arrow keys to select a device; if you highlight a  
SCSI hard drive and press ENTER, a small window showing the “Format Disk” and  
“Verify Disk” options is superimposed on the screen.  
Format Disk: Use this option to perform a low-level disk format on the target  
disk drive. (Be aware that this will erase all the data resident on the drive; make  
sure to back up any data you want to keep!)  
A new SCSI disk drive is normally low-level-formatted at the factory before it is  
shipped in order to simplify installation. Usually you can use new SCSI drives right  
out of the box, as soon as you partition them (refer to your operating system’s  
documentation for how to do this), without having to do a low-level format.  
Drives that have been previously used with other SCSI adapters, on the other  
hand, should be low-level-formatted before you use them with your new Ultra2  
LVD SCSI Host Adapter; this will prevent any operating or reliability problems that  
might otherwise arise as a result of incompatibilities between the different  
Adapters. The low-level format will erase the target drive and reset it to a state  
which is easily recognized by the Adapter across the SCSI bus. Once this format is  
complete, you will need to partition the drive.  
For more information about hard-disk preparation, see Section 4.4.  
Verify Disk: This option will test the integrity of the recording medium of a  
properly formatted drive and determine whether or not the drive is functioning  
properly. During the test process, any bad sectors on the disk will be identified and  
flagged so that the computer doesn’t try to write to or read from them. If a bad  
sector is found, you will be offered two options for what to do about it: “Reassign”  
(mask the flagged bad sector and reassign its sector number to a good sector in  
one of the reserved “replacement” areas on the disk) or “Skip” (do not reassign the  
number of the flagged sector).  
4.6.7 EXITING THE UTILITY  
To exit the Setup Utility, press <ESC> (esacape) at any time. and select “Yes” when  
you are asked to confirm that you want to exit. Any changes you might have made  
with the Setup Utility will be saved in the Ultra2 LVD SCSI Host Adapter’s NVRAM  
as soon as you make them, but will not take effect until you reboot the computer.

CHAPTER 5: Driver Installation  
5. Driver Installation  
This chapter describes how to install the necessary Ultra2 LVD SCSI Host Adapter  
driver(s) for each of the operating systems that the Adapter supports. As you read  
these instructions, please keep in mind that any text enclosed by <angle brackets>  
is actually the name of a keyboard key: For example, if you are instructed to type  
“<ENTER>”, that means you should press the ENTER key on your PC keyboard.  
Similarly, <ESC> stands for the ESC (Escape) key, <CTRL> for the CTRL (Control)  
key, <ALT> for the ALT (Alternate) key, and <DEL> for the DEL (Delete) key.  
5.1 Installing Drivers for MS-DOS  
CAUTION!  
The Adapter can be used, in a limited way, in PCs running  
Windows 3.1x: Once you boot into DOS and use the procedure in  
Section 5.1.1 to install the MS-DOS drivers on your system, they will  
enable your Windows 3.1x machine to control hard drives and CD-ROM  
drives. However, Adapters installed in Windows 3.1x PCs can’t support  
any other types of SCSI devices, so we strongly recommend that you  
upgrade your operating system rather than operate the Adapter in a  
Windows 3.1x PC.  
The Ultra2 LVD SCSI Host Adapter’s ASPI driver will support extended SCSI  
command functions for MS-DOS 3.30 or later. The on-board BIOS initialized  
during the power-up boot routine only supports MS-DOS hard-disk operation. If  
you use CD-ROM and/or MO disks, you’ll need to install the Adapter’s CD-ROM  
and/or MO drivers as well as its ASPI driver. If you use other types of SCSI  
peripherals, such as tape drives, you will need to install a third-party driver as well  
as the ASPI driver.  
The installation procedure guides you through the installation of the DOS ASPI  
driver. The installation procedure described here requires some experience in  
MS-DOS system setup and administration. The device driver is transferred from  
Driver Disk 1 to the hard drive, from which it is automatically loaded during the  
system boot routine.

ULTRA2 LVD SCSI HOST ADAPTER  
5.1.1 INSTALLING THE ASPI DRIVER IN AN EXISTING MS-DOS SYSTEM  
The ASPI driver is on Driver Disk 1. It is important that the SCSI hardware and the  
operating system are installed correctly before proceeding further. If you need  
help installing the MS-DOS operating system, please refer to the MS-DOS manual  
before proceeding.  
1. Turn on the host system and boot into MS-DOS.  
2. Insert Driver Disk 1 in your floppy drive.  
3. At the MS-DOS prompt, change to your active floppy drive: Assuming the  
floppy drive is drive A:, type “A: <ENTER>”.  
4. Type “DOSSETUP <ENTER>”.  
5. A series of screens will guide you through the installation of the ASPI device  
drivers. The first screen sets the installation drive and directory that the ASPI  
driver will be installed on. Follow the on-screen directions and/or options to  
continue the installation.  
6. To activate the device driver, reboot the system by selecting the “Reboot Now”  
option at the end of the installation process.  
5.1.2 COMMAND-LINE OPTIONS FOR THE ASPI DEVICE DRIVER  
The Ultra2 LVD SCSI Host Adapter’s ASPI device driver supports command-line  
switches to optimize driver operation. Device drivers normally require no additonal  
information to work effectively, but for your system or applications you might need  
to turn certain features ON or OFF. In the CONFIG.SYS file, use the following  
standard command format to modify the device driver’s switches:  
DEVICE = C:\INIASPI\ASPIA100.SYS [driver-config option]  
The “driver-config options” are:  
/D  
Verbose Mode provides detailed information about the driver on the  
system command line when the driver is initialized.  
/L  
The driver scans eight LUNs (logical unit numbers) for each SCSI  
target.  
/Bb,dd  
Scan device only on PCI BUS #b, PCI DEVICE #dd  
The range for “b” is from 0 to 7 decimal.  
The range for “dd” is from 0 to 20 decimal.  
/Bb  
Scan all the devices on PCI BUS #b  
The range for “b” is from 0 to 7 decimal.

CHAPTER 5: Driver Installation  
/Sdd Scan device only on PCI BUS #0 and device #dd  
The range for “dd” is from 0 to 20 decimal.  
/CCBSx Defines the maximum number of concurrent I/O operations that  
driver supports.  
The range for “x” is from 1 to 16 decimal.  
5.1.3 THE ASPI CD-ROM DRIVER AND ITS COMMAND-LINE OPTIONS  
INICD.SYS is a DOS device driver for SCSI CD-ROM drives. It functions as the  
interface between these drives and the generic Microsoft CD-ROM driver,  
MSCDEX.EXE. INICD.SYS requires that the Ultra2 LVD SCSI Host Adapter’s ASPI  
Manager be loaded. A “DEVICE=” or “DEVICEHIGH=” command line to load  
INICD.S'YS is automatically added to the CONFIG.SYS startup file by the  
DOSSETUP or SETUP program. (You will be asked whether or not you want to  
load this driver high; the program will add the correpsonding command to  
CONFIG.SYS depending on how you answer.) INICD.SYS is on Driver Disk 1. It has  
three command-line options—/D:, /T, and /X:—as described below.  
/D: or /d:—Use this option to define a “device name” for a CD-ROM drive. This  
device name must also be passed to MSCDEX.EXE on its command line (using the  
same /D: or/d: option). The name specified must be eight characters or fewer in  
length. Valid characters are uppercase letters “A” through “Z,” lowercase letters “a”  
through “z,” the digits “0” through “9,” and the underscore character. The name  
must start with a letter. Examples of valid command-line phrases:  
• /D:INICD001  
• /d:mscd001  
• /d:MYCD_01  
/T or /t—Use this option to specify a timeout value to be used when sending  
commands to a CD-ROM drive. If a CD-ROM drive does not respond to a  
command within the specified timeout period, the command will be aborted and  
an appropriate error message will be displayed. The timeout value is specified in  
minutes. Valid values are “1” (one minute) through “9” (nine minutes) and “D” or  
“d” (timeout disabled). We do not recommend disabling the timeout—if you do,  
faulty hardware will be able to lock up your system. Examples of valid command-  
line phrases:  
• /T4  
• /Td  
• /TD  
• /T1  
39  
Download from Www.Somanuals.com. All Manuals Search And Download.  
ULTRA2 LVD SCSI HOST ADAPTER  
/X: or /x:—Use this option to exclude particular CD-ROM drives from having their  
I/O handled by INICD.SYS. Excluded CD-ROM drives are identified by specifying  
the host adapter, target ID, and LUN (logical unit number). These values are  
separated by a colon. Groups of CD-ROM drives can also be identified. Examples  
of the different ways CD-ROM drives can be excluded:  
• /X0:1:2 This will exclude the drive on SCSI Host Adapter 0 (that is, the  
Adapter on the PCI bus that the motherboard has designated  
number zero) whose target ID is 1 and whose LUN is 2.  
• /X0:2  
This will exclude the drives on SCSI Host Adapter 0 whose target  
ID is 2, no matter what LUN they have.  
• /X0  
This will exclude all of the drives on SCSI Host Adapter 0.  
When DOSSETUP installs INICD.SYS, it will add command lines like those shown  
below to your CONFIG.SYS and AUTOEXEC.BAT files. (These examples assume  
that the Adapter drivers have been installed in the “C:\INIASPI” directory. The  
device name must be exactly the same in both the CONFIG.SYS and  
AUTOEXEC.BAT entries.)  
CONFIG.SYS:  
DEVICEHIGH=C:\INIASPI\ASPIA100.SYS  
DEVICEHIGH=C:\INIASPI\INICD.SYS /D:INICD001  
The first line loads the ASPI Manager and the second line loads the CD-ROM driver,  
specifying the device name “INICD001” for the CD-ROM drive.  
AUTOEXEC.BAT:  
C :\INIASPI\MSCDEX /D:INICD001  
This line loads the Microsoft supplied MSCDEX.EXE driver, instructing it to attach to the  
CD-ROM drive “INICD001.” SETUP copies MSCDEX to the INIASPI directory during  
installation.

CHAPTER 5: Driver Installation  
5.1.4 THE ASPI REMOVABLE-DISK DRIVER AND ITS COMMAND LINE OPTIONS  
INIDISK.SYS is a DOS “block” device driver for supporting SCSI fixed disks,  
removable disks, and MO (magneto-optical) devices. INIDISK.SYS requires that the  
Ultra2 LVD SCSI Host Adapter’s ASPI Manager be loaded. A “DEVICE=” or  
“DEVICEHIGH=” command line to load INIDISK.S'YS is automatically added to  
the CONFIG.SYS startup file by the DOSSETUP program. (You will be asked  
whether or not you want to load this driver high; the program will add the  
correpsonding command to CONFIG.SYS depending on how you answer.)  
INIDISK.SYS is on Driver Disk 1. It has three command-line options—/R, /T, and  
/X:—as described below.  
/R or /r—This option specifies the number of logical drives to reserve for MO and  
removable-disk devices. MO and removable-disk media are capable of being  
partitioned just like a fixed disk. For every DOS partition on the medium, a logical  
DOS drive letter needs to be available. INIDISK.SYS will support as many logical  
drives as required (up to the maximum supported by DOS), based on the  
partitioning of the medium that is present when your system boots. However, the  
medium may be removed at any time and a new disk may be inserted. The new disk  
may have more (or fewer) partitions then the original disk.  
Use this option to reserve drive letters at startup in order to make it possible to  
swap in a disk with more partitions than the original disk present at boot time had.  
The value after the /R or /r determines how many drive letters will be reserved per  
device. For example, if the user specifies /R4 and there are two devices attached to  
the SCSI bus, then a total of eight drive letters will be reserved.  
/T or /t—Use this option to specify a timeout value to be used when sending  
commands to a SCSI drive. If a SCSI drive does not respond to a command within  
the specified timeout period, the command will be aborted and an appropriate  
error message will be displayed. The timeout value is specified in minutes. Valid  
values are “1” (one minute) through “9” (nine minutes) and “D” or “d” (timeout  
disabled). We do not recommend disabling the timeout—if you do, faulty  
hardware will be able to lock up your system. Examples of valid command-line  
phrases:  
• /T4  
• /Td  
• /TD  
• /T1

/X: or /x:—Use this option to exclude particular SCSI drives from having their  
I/O handled by INIDISK.SYS. Excluded SCSI drives are identified by specifying the  
host adapter, target ID, and LUN (logical unit number). These values are  
separated by a colon. Groups of SCSI drives can also be identified. Examples of the  
different ways CD-ROM drives can be excluded:  
• /X0:1:2 This will exclude the drive on SCSI Host Adapter 0 (that is, the  
Adapter on the PCI bus that the motherboard has designated  
number zero) whose target ID is 1 and whose LUN is 2.  
• /X0:2  
This will exclude the drives on SCSI Host Adapter 0 whose target  
ID is 2, no matter what LUN they have.  
• /X0  
This will exclude all of the drives on SCSI Host Adapter 0.  
When DOSSETUP installs INIDISK.SYS, it will add command lines like those  
shown below to your CONFIG.SYS file. (These examples assume that the Adapter  
drivers have been installed in the “C:\INIASPI” directory.)  
CONFIG.SYS:  
DEVICEHIGH=C:\INIASPI\ASPIA100.SYS  
DEVICEHIGH=C:INIASPI\INIDISK.SYS /R2  
The first line loads the ASPI Manager and the second line loads the SCSI disk driver,  
specifying that a minimum of two drive letters be reserved for each MO and removable  
disk attached to the SCSI bus.

CHAPTER 5: Driver Installation  
5.1.5 THE ASPI PARTITION & FORMAT UTILITY  
INIFDISK.EXE is a DOS ASPI partition-and-format utility. It requires the  
ASPIA100.SYS and INIDISK.SYS drivers to be loaded in order for it to function  
properly. INIFDISK.EXE is installed by the DOSSETUP program. It can partition  
and format any SCSI storage device that is not being controlled by the BIOS; this  
includes SCSI hard disks, magneto-optical drives, and removable-media devices.  
When you run INIFDISK, its initial screen will have two windows. The top  
window will list all of the SCSI devices installed in the system; you can use the up-  
and down-arrow keys to highlight a particular device. The bottom window will  
display information about the device that is currently highlighted in the top  
window.  
Once you select a storage device, INIFDISK will display a second two-part screen.  
Its top window will list all of the device’s logical drives or volumes, physical  
partitions, etc. Before you can erase existing physical partitions on a device, you  
have to remove all of their logical divisions; when you select a device element  
(drive, volume, partition, etc.), the bottom window will show the commands for  
everything it is currently possible to do with that element, and will explain why  
certain things are not yet possible to do.

5.2 Installing Drivers for Windows 95  
NOTE  
The procedure for installing drivers in Windows 98 is not the same as  
the procedure used for Windows 95. If you are running Windows 98,  
skip to Section 5.3.  
With an additional software driver, your Ultra2 LVD SCSI Host Adapter will support  
Microsoft Windows 95 and Windows 95b (OSR2). The installation procedure  
described here requires some experience in Windows 95 system setup and  
administration. The device driver is transferred from Driver Disk 1 to the hard  
drive, from which it is automatically loaded during the system-boot routine.  
These installation files are in the “A:\WIN95” directory on Driver Disk 1:  
“A:\WIN95\INIA100.MPD” is the Adapter’s Windows 95 miniport driver, and  
“A:\WIN95\INIA100.INF” is the Windows 95 installation-information file.  
The Adapter’s Windows 95 driver is loaded during the system-boot routine and  
will remain resident on the drive. This is accomplished by following one of the six  
installation procedures listed in this section. There are three procedures for each  
of the two major versions of Windows 95 (95/95a and 95b): new Windows 95  
installation, adding the Adapter’s Windows 95 device driver to an existing  
Windows 95 system, or updating the INIA100.MPD device driver.  
NOTE  
For users who are adding or updating the driver in an existing system:  
To determine which version of Windows 95 you have, check the dates of  
the files in your WINDOWS directory. If most of the files are dated  
07/11/95, your Windows 95 is the first-release version. If they’re dated  
12/31/95, you have Windows 95a or Windows 95 with Service Pak 1. If  
they’re dated 08/24/96, you have Windows 95b or OSR2.  
These procedures differ significantly from one another. We strongly suggest that  
you carefully read the instructions for the procedure you plan to use and make  
sure you understand them before proceeding with the corresponding system-  
configuration changes.

CHAPTER 5: Driver Installation  
5.2.1 NEW WINDOWS 95/95A INSTALLATION  
These instructions (beginning on the next page) will guide you through the  
installation of the Ultra2 LVD SCSI Host Adapter’s Windows 95 driver while  
installing Windows 95 or 95a itself. Windows 95/95a will be installed from either a  
CD-ROM or floppy diskettes. It is important that the hardware and DOS 4.01 or  
higher have been installed successfully before proceeding further. If you are  
installing from a SCSI CD-ROM drive, it is important that the Adapter’s ASPI driver  
and CD-ROM driver be installed (see Section 5.1) before proceeding further.  
1A. If you’re installing from CD-ROM: Access the Windows 95/95a CD-ROM either  
from the DOS prompt or from the Microsoft Windows 3.x File Manager.  
Execute the SETUP.EXE program and follow the instructions on your screen.  
1B. If you’re installing from floppy diskette: Put Windows 95/95a Setup Disk 1 in your  
floppy-disk drive and boot your system. Follow the instructions on your screen.  
2. Once a Windows 95 session is established, start from the desktop and use your  
installed mouse or the appropriate keystrokes to select these items one after  
the other (each item contains the next in sequence): “My Computer,”  
“Control Panel,” “System,” “Device Manager” tab, “Other Devices” category,  
“PCI-SCSI Bus Controller” subcategory.  
3. In the “PCI SCSI Bus Controller Properties” window, select the “Driver” tab,  
then select “Change Driver...”.  
4. In the “Select Hardware Type” window, select “SCSI Controllers.”  
5. In the “Select Device” window, select “Have Disk...”.  
6. When the “Install from Disk” window is displayed, insert Driver Disk 1 into  
drive A:, then enter the pathname of the Windows 95 driver’s directory  
(“A:\WIN95”) and select “OK”.  
7. Select “Initio INI-A100U2W PCI SCSI Controller”, select “OK”, then “OK”  
again to install the INIA100.MPD driver on your hard-disk drive. (Because of  
a Windows quirk, the A:\WIN95 directory might become deselected; it might  
be necessary to direct Windows back to A:\WIN95—possibly several times—  
before it actually copies the driver.)  
8. This completes installing the Adapter’s device driver. Reboot the system to  
activate the driver.

ULTRA2 LVD SCSI HOST ADAPTER  
9. We highly recommend that you verify that your Windows 95 device driver has  
been properly installed by starting at the desktop and selecting these items  
one after the other (each item contains the next in sequence): “My  
Computer,” “Control Panel,” “System,” “Device Manager” tab, “SCSI  
Controllers” category, “Initio INI-A100U2W PCI SCSI Controller.” If “This  
device is working properly” is displayed on your screen, the driver has been  
correctly installed.  
5.2.2 ADDING THE WINDOWS 95 DRIVER TO AN EXISTING WINDOWS 95/95A SYSTEM  
These instructions will guide you through the installation of the Ultra2 LVD SCSI  
Host Adapter’s Windows 95 driver in an existing Windows 95 or 95a system.  
Windows 95 will automatically detect the presence of new hardware in Plug-and-  
Play compliant systems. It is important to make sure that the Adapter hardware has  
been properly installed before proceeding further.  
1. Reboot the system. Microsoft Windows 95 will detect the presence of new  
hardware at bootup and will display a dialog window titled “New Hardware

CHAPTER 5: Driver Installation  
5.3 Installing Drivers for Windows 98  
With an additional software driver, your Ultra2 LVD SCSI Host Adapter will support  
Microsoft Windows 98. The installation procedure described here requires some  
experience in Windows 98 system setup and administration. The device driver is  
transferred from Driver Disk 1 to the hard drive, from which it is automatically  
loaded during the system-boot routine.  
These installation files are in the “A:\WIN95” directory on Driver Disk 1, because  
they are identical to the files used for Windows 95: “A:\WIN95\INIA100.MPD” is the  
Adapter’s Windows 95/98 miniport driver, and “A:\WIN95\INIA100.INF” is the  
Windows 95/98 installation-information file.  
The Adapter’s Windows 98 driver is loaded during the system-boot routine and  
will remain resident on the drive. This is accomplished by following one of the  
three installation procedures listed in this section: new Windows 98 installation,  
adding the Adapter’s Windows 98 device driver to an existing Windows 98 system,  
or updating the INIA100.MPD device driver. These procedures differ significantly  
from one another. We strongly suggest that you carefully read the instructions for  
the procedure you plan to use and make sure you understand them before  
proceeding with the corresponding system-configuration changes.

CHAPTER 5: Driver Installation  
5.4 Installing Drivers for Windows NT  
With an additional software driver, your Ultra2 LVD SCSI Host Adapter will support  
Windows NT 3.5x or 4.0. With such a software driver, the host computer can  
transfer data over the SCSI bus. The Adapter’s device driver for Windows NT is  
copied from Driver Disk 1 to your hard drive, from which it is automatically loaded  
during the system boot routine.  
The following files are used for installation and will be found on Driver Disk 1:  
“INIA100.SYS” is the Adapter’s Windows NT miniport driver, “TXTSETUP.OEM”  
is the script file for installing INIA100.SYS during the text-only setup phase, and  
“OEMSETUP.INF” is the script file for installing INIA100.SYS during the windowed  
phase.  
The Adapter’s Windows NT driver will be installed on the boot drive. The driver  
is loaded during the system boot routine and will remain resident on the drive.  
This is accomplished by following one of the four installation procedures listed in  
this section: regular new Windows NT installation, new Windows NT installation  
from bootable CD, diskless new Windows NT installation, or adding or updating  
the Adapter driver in an existing Windows NT system. These procedures differ  
significantly from one another. We strongly suggest that you carefully read the  
instructions for the procedure you plan to use and make sure you understand  
them before proceeding with the corresponding system-configuration changes.  
In addition, if you are installing the Adapter’s Windows NT driver before you  
install the Adapter itself, follow the procedure in Section 5.4.5 to correctly add the  
Adapter hardware to your system.

5.5 Installing Drivers for Novell NetWare  
With additional software drivers, your Ultra2 LVD SCSI Host Adapter will support  
Novell NetWare 386, v3.1x, v4.1x, or v5.0. (Note, however, that users of versions of  
NetWare earlier than v5.0 must upgrade their systems with the NWPA [NetWare  
Peripheral Architecture] in order to be able to use the Adapter, because there are  
no .DSK drivers for it—see the README.TXT file on Driver Disk 1 for more  
information.) The installation procedure described here requires some experience  
in Novell system setup and administration. The device drivers are transferred from  
Driver Disk 1 to the hard drive from which they are automatically loaded during  
the system boot routine. The diskette contains these driver files:  
\NETWARE\HAM\INIA100.HAM  
\NETWARE\HAM\INIA100.DDI  
HAM device driver  
HAM device-driver installation file  
The NetWare driver will be installed on the disk drive used for NetWare system  
initialization. The driver is loaded during the system boot routine and will remain  
resident on the drive. This is accomplished by following one of the two installation  
procedures listed in this section: new NetWare installation, or adding the Adapter  
drivers to an existing NetWare system.  
These procedures differ significantly from one another. We strongly suggest that  
you carefully read the instructions for the procedure you plan to use and make  
sure you understand them before proceeding with the corresponding system-  
configuration changes. In addition, Driver Disk 1 contains a README.TXT file

CHAPTER 5: Driver Installation  
5.5.4 COMMAND-LINE OPTIONS FOR THE DEVICE DRIVERS  
The Ultra2 LVD SCSI Host Adapter’s device drivers support command-line switches  
to optimize driver performance. Device drivers normally require no additonal  
information to work effectively, but for your system or applications you might need  
to turn certain features ON or OFF.  
To enter command-line switches, add the following command statement to  
STARTUP.NCF, where “[pathname]” is the first part of the pathname  
(drive:\dir\.subdir...) where INIA100.HAM is installed:  
LOAD [pathname]INIA100 [driver-config option]  
The “driver-config options” are:  
/V  
Verbose Mode provides detailed information about the driver on the  
system command line when the driver is initialized  
/!V  
/L  
Non-Verbose Mode (default)  
Driver assumes that all targets have more than one LUN (logical unit  
number)  
/!L  
Driver assumes that all targets only have LUN 0 (default)  
/T:hhhh Target-enable mask word (default: FFFF hex, scan all targets)  
The range for “hhhh” is from 0000 hex (disable all targets) to  
FFFF hex (scan all targets).  
This is a powerful and complex option by which you can have the  
driver control only certain selected devices. Each of the four hex  
characters stands for four of the SCSI IDs, each of which has its own  
corresponding bit for which “1” = control enabled, “0” = control  
disabled. For example, if you wanted the driver to be able to control  
all of the devices on the bus except a CD-ROM drive on ID 3, a tape  
drive on ID 6, and scanners on IDs 9 and 10, you would enter the  
command phrase “/T:F9B7”:

CHAPTER 5: Driver Installation  
5.6 Installing Drivers for IBM OS/2  
The OS/2 driver for your Ultra2 LVD SCSI Host Adapter will support OS/2 3.0 and  
4.0. The device driver for OS/2 is copied from Driver Disk 1 to your hard drive,  
from which it is automatically loaded during bootup. The files on Driver Disk 1  
associated with the OS/2 driver are “\OS2\INIA100.ADD” (the driver itself) and  
“\OS2\INIA100.DDP” (the script file for installing the driver).  
The Adapter driver developed for OS/2 will be installed on the disk drive used  
for system initialization. The driver is loaded during the system boot routine and  
will remain resident on the drive. This is accomplished by following one of the two  
installation procedures listed in this section: either for new OS/2 installation or for  
adding the Adapter’s OS/2 device driver to an existing OS/2 system.  
These procedures differ significantly from one another. We strongly suggest that  
you carefully read the instructions for the procedure you plan to use and make  
sure you understand them before proceeding with the corresponding system-  
configuration changes. In addition, Driver Disk 1 contains a README.TXT file  
that might contain important updated information about the procedures  
described in this chapter; we recommend that you read it and use it when you  
perform the driver installation.

ULTRA2 LVD SCSI HOST ADAPTER  
5.6.1 NEW OS/2 INSTALLATION  
These instructions will guide you through installing both OS/2 itself and the  
Ultra2 LVD SCSI Host Adapter’s OS/2 device driver at the same time. The OS/2  
operating system can be installed from floppy diskettes or from CD-ROM. The  
Adapter’s OS/2 driver is on Driver Disk 1. It is important that the Adapter  
hardware has been installed successfully before proceeding further.  
1. Make a backup copy of OS/2 Diskette 1 using a blank diskette and label it  
something like “OS/2 Diskette 1 for SCSI Adapter”.  
2. Copy the “\OS2\INIA100.ADD” file from Driver Disk 1 to the root directory on  
the “OS/2 Diskette 1 for SCSI Adapter” you just made.  
3. Using an appropriate text editor, modify the CONFIG.SYS file on the “OS/2  
Diskette 1 for SCSI Adapter” by adding these lines for the Adapter driver at  
some point after the “SET OS2_SHELL=CDINT.EXE” line  
:
BASEDEV=INIA100.ADD  
SET COPYFROMFLOPPY=1  
Once you’ve added thes lines, save the file.  
4. Insert the Installation Diskette—this is another one of the operating system  
diskettes—into drive A: and turn on your computer. This will begin the OS/2  
installation and establish an OS/2 bootable hard drive.  
5. When prompted, insert the “OS/2 Diskette 1 for SCSI Adapter”. Follow the  
on-screen instructions to continue.  
6. This completes the Adapter’s device-driver installation for OS/2. Follow the  
on-screen instructions to finish your OS/2 installation; also refer to your  
OS/2 manual for a complete description of installation procedures.

5.6.3 COMMAND-LINE OPTIONS FOR THE DEVICE DRIVER  
The Ultra2 LVD SCSI Host Adapter’s device drivers support command-line switches  
to optimize driver performance. Device drivers normally require no additonal  
information to work effectively, but for your system or applications you might need  
to turn certain features ON or OFF. In the CONFIG.SYS file, use the following  
standard command format to modify the device driver’s switches:  
BASEDEV = INIA100.ADD [driver-config option]  
The “driver-config options” are:  
/V  
Verbose Mode provides detailed information about the driver on  
the system command line when the driver is initialized  
/!V  
Non-Verbose Mode (default)  
/ET  
Driver assumes that all targets have more than one LUN (logical  
unit number)  
/!ET  
Driver assumes that all targets only have LUN 0 (default)

5.7 Installing Drivers for Linux  
Drivers have been developed for the Ultra2 LVD SCSI Host Adapter for use with  
most of the major distributions of Linux. However, the procedures for installing  
these drivers and recompiling the operating system vary from distribution to  
distribution and change frequently. Because this is the case, the procedures for  
installing these drivers aren’t included in this manual. Instead, take these steps:  
NOTE  
This procedure might change as our Web and ftp sites change. If you  
can’t find the necessary files, please call the Conversions group of Black  
Box Technical Support for assistance.  
1. Go to our Web site at http://www.blackbox.com and select “Software Updates.”  
This will take you to ftp://ftp.blackbox.com/pub.  
2. Select the “Conversions” folder.  
3. When the Conversions page is displayed, download the “linux515.zip” file; this  
archive will contain driver source code along with instructions for installing and  
compiling it.

CHAPTER 5: Driver Installation  
5.8 Installing Drivers for SCO UNIX  
The SCO UNIX device driver for your Ultra2 LVD SCSI Host Adapter will support  
SCO UNIX System V/386 Release 3.2v4.0 or later; SCO Open Desktop v2.0, 3.0, or  
later; and SCO Open Server Releases 3.0 and 5.0.x. The device drivers are  
transferred from the floppy diskette to the hard drive, from which they are loaded  
during system initialization. The two SCO UNIX device-driver files on Driver Disk 2  
are the object file “driver.o” and the definition file “space.c”. Before proceeding,  
you might want to have the following reference documentation handy in addition  
to this manual:  
• SCO UNIX documentation, installation and user’s guide  
• The systems setup and installation guide  
• The documentation for your system peripherals  
• Any README.TXT file contained on Driver Disk 2. Such a file might contain  
important updated information about driver-installation procedures.  
The Adapter drivers developed for SCO UNIX will be installed on the disk drive  
used for system initialization. The drivers are loaded during the system boot  
routine and will remain resident on the drive. This is accomplished by following  
one of the three installation procedures listed in this section: new SCO UNIX  
installation, adding the device drivers to an existing SCO UNIX system (Adapter is  
not bootable), or adding the drivers to an existing system and making the Adapter  
bootable. These procedures differ significantly from one another. We strongly  
suggest that you carefully read the instructions for the procedure you plan to use  
and make sure you understand them before proceeding with the corresponding  
system-configuration changes.  
Another thing you need to check on before you go any further is the interrupt  
and SCSI ID settings in your system:  
• You can assign interrupt-request level (IRQ) 9, 11, or 15 to the Ultra2 LVD  
SCSI Host Adapter; we recommend IRQ 11. Avoid using IRQ 10 as the  
Adapter’s interrupt.  
• Set the primary SCSI disk (the boot disk) to ID 0 (this is a first-time-installation  
requirement)  
• If you’ve attached a tape drive to the Adapter, set its target ID to 2. (Please be  
aware that you will still need a third-party driver for any tape drive.)  
•
If you’ve attached a CD-ROM drive to the Adapter, set its target ID to 5. (Please  
be aware that you will still need a third-party driver for any CD-ROM drive.)  
Please refer to your system’s documentation to set the interrupt levels and to your  
peripherals’ documentation for help in setting SCSI IDs.

5.9 Installing Drivers for SCO UnixWare  
The SCO UnixWare device driver for your Ultra2 LVD SCSI Host Adapter will  
support UnixWare 2.1x. The device driver is transferred from Driver Disk 2 to the  
hard drive, from which it is loaded during system initialization.  
The Adapter drivers for SCO UnixWare will be installed on the disk drive used  
for system initialization. The drivers are loaded during the system boot routine and  
will remain resident on the drive. This is accomplished by following one of the two  
installation procedures listed in this section: new SCO UnixWare installation or  
adding the device drivers to an existing SCO UnixWare system. (There are also  
procedures listed for using multiple Adapters and for removing the driver.) These  
procedures differ significantly from one another. We strongly suggest that you  
carefully read the instructions for the procedure you plan to use and make sure  
you understand them before proceeding with the corresponding system-  
configuration changes. In addition, Driver Disk 2 contains a README.TXT file  
that might contain important updated information about the procedures  
described in this chapter; we recommend that you read it and use it when you  
perform the driver installation.  
The Adapter’s interrupt-request level (IRQ) must be set to IRQ 10 for the driver  
to install properly. Please refer to your system documentation to set the interrupt  
levels and your peripheral documentation for help in setting SCSI IDs.  
5.9.1 INSTALLING THE DRIVER IN A NEW UNIXWARE SYSTEM  
SCO UnixWare drivers for the Ultra2 LVD SCSI Host Adapter are on Driver Disk 2.  
In most cases you will load the drivers during a new installation of UnixWare from  
CD-ROM. The driver is loaded during the early stages of the installation  
procedure. The UnixWare installation program will prompt you for the required  
parameters as the installation procedure progresses. We highly recommended that  
you have copies of the SCO UnixWare Installation Handbook and SCO UnixWare  
System Owner Handbook for reference.

Y <ENTER>  
4 Exit the UnixWare program and reboot your system to initialize the new  
device driver to control the Adapter.  
5.9.3 USING MULTIPLE HOST ADAPTERS  
UnixWare is capable of supporting up to eight SCSI buses. If you choose to use  
multiple host adapters in your system—even if they are different models or  
makes—verify that each host adapter’s shared interrupt level is set to IRQ10. Please  
refer to your system documentation to set the interrupt levels.  
You should configure and allocate space for each host adapter in the system by  
making sure there is a separate line for each adapter in the “/etc/conf/sdevice.d/  
a100” file. Make sure that “Y” is selected in the second field of each of these lines  
that correspond to one of our Ultra2 LVD SCSI Host Adapters, so that their I/O  
can be handled by the a100 driver that was designed for them. UnixWare will  
automatically rebuild the kernel when an additional Adapter is detected.

CHAPTER 5: Driver Installation  
5.9.4 REMOVING THE DRIVER FROM A UNIXWARE SYSTEM  
1. Once a UnixWare session is established and a command prompt is ready, type  
“/etc/conf/bin/idinstall -d a100 <ENTER>” (recall that UnixWare is case-  
sensitive) to delete these files:  
/etc/conf/mdevice.d/a100  
/etc/conf/sdevice.d/a100  
/etc/conf/pack.d/a100/driver.o  
/etc/conf/pack.d/a100/space.c  
/etc/conf/pack.d/a100/disk.cfg  
2. Then rebuild the UnixWare kernel by executing the following commands at  
the system prompt:  
/etc/conf/bin/idbiuld -B -K <ENTER>  
/cp /etc/conf/cf.d/unix /stand/unix <ENTER>  
cd/ <ENTER>  
shutdown -g0 <ENTER> (the “0” in “-g0” is a zero)  
Y <ENTER>

ULTRA2 LVD SCSI HOST ADAPTER  
6. Troubleshooting  
6.1 Installation-Time Problems  
If you have difficulty installing your Ultra2 LVD SCSI Host Adapter, check these  
things first:  
1. Have you installed the Adapter in a PCI Rev. 2.0 compliant computer?  
2. Are all SCSI devices powered?  
3. Are all SCSI bus cables and power cables properly connected? Is Pin 1  
oriented correctly?  
4. Do the Adapter and all devices on the SCSI bus have unique IDs?  
5. Are all devices on the SCSI bus terminated properly?  
6. Is the drive type in your motherboard’s CMOS setup set to “Not installed”?  
7. Does your system CMOS setup require you to enable PCI bus parameters? If  
so, see your computer’s documentation. Check that IRQ-channel assignment  
and BIOS settings have been made.  
8. Did you install your Adapter in a PCI slot capable of busmastering? Refer to  
your computer’s documentation or try another slot.  
Here are some commonly asked questions and answers regarding problems that  
can be encountered during the installation of an Adapter:  
• Question: What is Ultra2 SCSI?  
Answer: Ultra2 is a high-level SCSI specification. Because they use Low Voltage  
Differential (LVD) technology, which is designed into the chipset and is less  
susceptible to noise and uses less power than earlier SCSI implementations,  
Ultra2 devices such as the Adapter are able to support Ultra2 Wide SCSI  
peripherals with a SCSI burst-transfer speeds up to 80 Megabytes per second  
and point-to-point (Adapter-to-single-device) cable lengths up to 25 meters  
(82 ft.) or multipoint (Adapter-to-multiple-devices) cable lengths up to  
12 meters (39.4 ft.).

CHAPTER 6: Troubleshooting  
• Question: Can I use the Adapter with my legacy Ultra SCSI, SCSI-2, and SCSI-1  
devices?  
Answer: Yes, as long as they’re single-ended; but the Adapter’s SCSI bus will  
become limited to (a) the top speed supported by your slowest device and  
(b) the maximum length supported by your shortest-distance device. The  
Adapter does not work with older differential SCSI devices.  
• Question: Can I use the same cables for Ultra2 SCSI devices as I use for regular  
Ultra SCSI peripherals?  
Answer: We recommend that you use cables specifically designed for Ultra2  
devices. The Adapter comes with a terminated Ultra2 Wide cable with  
connectors for four internal Ultra2 peripherals.  
• Question: Why isn’t the banner “!!!Press < Ctrl > < I > to start Configuration  
Utility !!!” displayed when I power up the host system?  
Answer: Verify that the Adapter is securely seated in its PCI slot, and that its  
slot actually supports busmastering.  
• Question: At bootup the message “SCSI BIOS Installed” is displayed, but the  
system hangs.  
Answer: Verify that the CMOS interrupt structure is set to INTA (interrupt A)  
and that the CMOS IRQ level matches the jumper setting on the motherboard.  
Refer to your PC’s user's manual.  
• Question: At bootup, not all the peripherals are scanned and recognized.  
Answer: Verify that each of the SCSI devices on the bus has its own distinct  
SCSI ID number and that all peripherals are receiving power. Refer to your  
peripherals’ manuals for information about changing SCSI IDs.  
Verify that the SCSI termination is set correctly. Make sure that either the  
cable itself or the last peripheral on the SCSI bus is terminated. See the  
peripherals’ manuals for information about proper termination.  
After you take the above steps, if the Adapter is still not recognizing all  
attached peripherals, configure the Adapter to operate asynchronously by  
changing the “Asynchronous Transfer” setting in the Device Setup Menu of  
the firmware Setup Utility (see Section 4.6.3).  
• Question: At bootup, the message “Missing Operating System” is displayed.  
Answer: Is the boot drive larger than 1 GB? If so, verify that the “DOS Space >  
1GB” is enabled in the Device Setup Menu of the firmware Setup Utility (see  
Section 4.6.3).

ULTRA2 LVD SCSI HOST ADAPTER  
• Question: Is it really necessary to terminate the last SCSI device on the cable?  
Answer: Not if the cable itself is terminated. But if the cable is not terminated,  
you must make sure that the device is terminated. Improper termination at  
either end of the SCSI bus will cause the Adapter not to work properly, or even  
not to initialize at all (the driver will fail to load).  
• Question: How do I set the burst-transfer rate for SCSI devices?  
Answer: You can set the maximum synchronous transfer rate of a given device  
with the SmartSCSI Utility. To run the Utility, press <Ctrl> <I> at system  
bootup; click on “Device Setup” and follow the on-screen options to select the  
desired transfer rate (see Section 4.6.3).  
®
• Question: Under SCO UnixWare , the system displays a panic message or  
crashes during bootup.  
Answer: Reboot the system and verify that the interrupt setting of the  
Adapter’s kernel conforms to UNIX standards. Please refer to your system’s  
documentation for information about setting the interrupt levels and your  
peripherals’ documentation for help in setting SCSI IDs.  
In order to boot from the old UnixWare kernel, reboot the system and take  
the following steps:  
1. Begin an interactive boot session by pressing the space bar at the BOOTING  
UNIXWARE prompt.  
2. At the system’s [boot]# prompt, type KERNEL=unix.org < ENTER >.  
3. Type go < ENTER >.  
Consult the SCO UnixWare Installation Handbook’s “Troubleshooting” section to  
help isolate the problem. If it becomes necessary to remove the Adapter’s SCO  
UnixWare device driver, refer to Section 5.8.4.
