Product warranty  
Advantech warrants to you, the original purchaser, that each of its prod-  
ucts will be free from defects in materials and workmanship for two years  
from the date of purchase.  
This warranty does not apply to any products which have been repaired or  
altered by persons other than repair personnel authorized by Advantech,  
or which have been subject to misuse, abuse, accident or improper instal-  
lation. Advantech assumes no liability under the terms of this warranty as  
a consequence of such events.  
If an Advantech product is defective, it will be repaired or replaced at no  
charge during the warranty period. For out-of-warranty repairs, you will  
be billed according to the cost of replacement materials, service time and  
freight. Please consult your dealer for more details.  
If you think you have a defective product, follow these steps:  
Step 1. Collect all the information about the problem encountered. (For  
example, type of PC, CPU speed, Advantech products used,  
other hardware and software used, etc.) Note anything abnormal  
and list any on-screen messages you get when the problem  
occurs.  
Step 2. Call your dealer and describe the problem. Please have your man-  
ual, product, and any helpful information readily available.  
Step 3. If your product is diagnosed as defective, obtain an RMA (return  
material authorization) number from your dealer. This allows us  
to process your return more quickly.  
Step 4. Carefully pack the defective product, a fully-completed Repair  
and Replacement Order Card and a photocopy proof of purchase  
date (such as your sales receipt) in a shippable container. A prod-  
uct returned without proof of the purchase date is not eligible for  
warranty service.  
Step 5. Write the RMA number visibly on the outside of the package and  
ship it prepaid to your dealer.

Hardware  
Configuration  
This chapter provides background  
information on the PCA-6185. It will  
show you how to configure the card to  
match your application and prepare it  
for installation into your PC.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 1 Hardware Configuration  
1.1 Introduction  
The PCA-6185 Series all-in-one industrial grade single CPU card uses  
Intel's high performance Pentium® 4 processor, together with the Server-  
Works' GC-SL chipset. The card features two separate 64-bit PCI-X bus,  
one for internal deviced and one for external add-on cards. The dual PCI-  
X bus ensures the operation of internal devices not to be influenced by  
external add-on cards.  
The PCA-6185 supports Pentium 4 or Celeron CPU with 533 and 400  
MHz front side bus. Based on the NetBurst™ microarchitecture, the  
CPU is equipped with 512, 256 or 128 KB on-CPU full-speed cache  
memory, providing higher performance than ever before. The 3 DIMM  
memory sockets support up to 4 GB DDR200/266 registered SDRAM,  
fullfiling the demand on computing performance of most applications.  
The PCA-6185 Series features powerful on-board I/O functions such as  
single or dual gigabit Ethernet ports and dual channel Ultra 320 SCSI  
interface. This makes it an ideal choice for applications that require both  
high performance and full functionality.  
It has two EIDE interfaces (for up to four devices) and a floppy disk drive  
interface (for up to two devices). Other features include two RS-232  
serial ports (16C550 UARTs with 16-byte FIFO or compatible), one  
enhanced parallel port (supports SPP/EPP/ECP) and four USB (Universal  
Serial Bus) 1.1 ports. The PCI enhanced IDE controller supports ATA 33/  
66/100 and PIO Mode 4 operation. This provides data transfer rates of up  
to 100 MB/sec. System BIOS supports boot-up from an IDE CD-ROM,  
SCSI CD-ROM, LS-120, IDE HDD, SCSI HDD, ZIP-100, USB, LAN,  
and FDD.  
A backup of CMOS data is stored in the Flash memory, which protects  
data even after a battery failure. Also included is a 63-level watchdog  
timer, which resets the CPU or generates an interrupt if a program cannot  
be executed normally. This enables reliable operation in unattended envi-  
ronments.  
The remote management interface enables the PCA-6185 to be managed  
through Ethernet when it is connected to the SNMP-1000 Remote HTTP/  
SNMP System Manager.  
Note:  
Some of the features mentioned above are not available with all models. For  
more information about the specifications of a particular model, see Section  
1.3 Specifications.

1.2 Features  
1.  
High performance PCI bus: The PCA-6185 provides three inde-  
pendent PCI buses: one 32-bit, 33 MHz PCI bus and two 64-bit  
PCI-X buses. The 32-bit bus is used for on-board VGA controller.  
One of the two high performance PCI-X bus is used for onboard  
Gigabit Ethernet and SCSI controllers. The other PCI-X bus is  
available for user's add-on cards through the edge connector. This  
PCI-X bus is compatible with PCI bus and capable to operate at dif-  
ferent speed: 32-bit/33 MHz, 32-bit/66MHz, 64-bit/33 MHz or 64-  
bit/66 MHz.  
2.  
3.  
4.  
Fan status monitoring and alarm: To prevent system overheating  
and damage, the CPU fan can be monitored for speed and failure.  
The fan is set for its normal RPM range and alarm thresholds.  
Temperature monitoring and alarm: To prevent system over-  
heating and damage, the CPU card supports processor thermal  
sensing and auto-protection.  
Voltage monitoring and alarm: System voltage levels are moni-  
tored to ensure stable current flows to critical components. Voltage  
specifications will become even more critical for processors of the  
future. Thus monitoring will become ever more necessary to ensure  
proper system configuration and management.  
5.  
6.  
7.  
ATX soft power switch: Through the BIOS, the power button can  
be defined as the "Standby" (aka "Suspend" or "Sleep") button or as  
the "Soft-Off" button (see Soft-off by PWR-BTN, Setion 3.7.8)  
Regardless of the setting, pushing the power button for more than 4  
seconds will enter the Soft-Off mode.  
Message LED: Chassis LEDs now act as information providers.  
The way a particular LED illuminates indicates the stage the com-  
puter is in. A single glimpse provides useful information to the  
user.  
CMOS RAM backup: When BIOS CMOS setup has been com-  
pleted, data in the CMOS RAM is automatically backed up to the  
Flash ROM. This is particularly useful in industrial environments  
which may cause soft errors. Upon such an error occurring, BIOS  
will check the data, and automatically restore the original data for  
booting.

1.6 Safety Precautions  
Warning! Always completely disconnect the power cord  
from your chassis whenever you work with the  
hardware. Do not make connections while the  
power is on. Sensitive electronic components  
can be damaged by sudden power surges. Only  
experienced electronics personnel should open  
the PC chassis.  
Caution!  
Always ground yourself to remove any static  
charge before touching the CPU card. Modern  
electronic devices are very sensitive to static  
electric charges. As a safety precaution, use a  
grounding wrist strap at all times. Place all elec-  
tronic components in a static-dissipative surface  
or static-shielded bag when they are not in the  
chassis.  
1.7 Jumper Settings  
This section provides instructions on how to configure your card by set-  
ting jumpers. It also includes the card's default settings and your options  
for each jumper.  
1.7.1 How to set jumpers  
You configure your card to match the needs of your application by setting  
jumpers. A jumper is a metal bridge that closes an electrical circuit. It  
consists of two metal pins and a small metal clip (often protected by a  
plastic cover) that slides over the pins to connect them. To “close” (or  
turn ON) a jumper, you connect the pins with the clip. To “open” (or turn  
OFF) a jumper, you remove the clip. Sometimes a jumper consists of a set  
of three pins, labeled 1, 2, and 3. In this case you connect either pins 1  
and 2, or 2 and 3.  
A pair of needle-nose pliers may be useful when setting jumpers.  
1.7.2 CMOS clear (J1)  
The PCA-6185 CPU card contains a jumper that can erase CMOS data  
and reset the system BIOS information. Normally this jumper should be  
set with pins 1-2 closed. If you want to reset the CMOS data, set J1 to 2-3

closed for just a few seconds, and then move the jumper back to 1-2  
closed. This procedure will reset the CMOS to its default setting.

1.8 System Memory  
The top-left edge of the PCA-6185 contains three sockets for 184-pin  
dual inline memory modules (DIMMs). All these sockets accept only 2.5  
V registered DDR SDRAM. Registered DIMMs are available in capaci-  
ties of 128, 256, 512, 1024 or 2048 MB. The sockets can be filled in any  
combination with DIMMs of any size, with the limitation of the total  
memory capacity of 4 GB.  
1.8.1 Sample calculation: DIMM memory capacity  
Suppose you install a 128 MB DIMM into your PCA-6185's socket 1 and  
a 256 MB DIMM into sockets 2 and 3. Your total system memory is 640  
MB, calculated as follows:  
Table 1.6: DIMM memory capacity sample calculation

256 MB  
3
256 MB x 1  
256 MB  
Total memory: 640 MB  
1.8.2 Supplementary information about DIMMs  
Your PCA-6185 can accept only registered DDR SDRAM memory mod-  
ules. The register on the memory module secures reliable operation of  
high memory capacity under high speed. Also note:  
• Please use only DDR compliant registered DIMMS.  
Most systems will not even boot if non-compliant modules are  
used. This is due to strict timing issues involved at this speed.  
• You can find two or three additional register ICs on a registered  
SDRAM. These ICs are relatively smaller than the SDRAM ICs.  
• Registered SDRAM are usually with ECC function. Modules with  
9 or 18 SDRAM chips support ECC; modules with 8 or 16  
SDRAM chips do not support ECC.  
1.9 Memory Installation Procedures  
To install DIMMs, first make sure the two handles of the DIMM socket  
are in the "open" position. i.e. The handles lean outward. Slowly slide the  
DIMM module along the plastic guides on both ends of the socket. Then  
press the DIMM module right down into the socket, until you hear a  
click. This is when the two handles have  
PCA-6185 User’s Manual  
14  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
automatically locked the memory module into the correct position of the  
DIMM socket. To remove the memory module, just push both handles  
outward, and the memory module will be ejected by the mechanism in the  
socket.  
1.10 Cache Memory  
Since the second level (L2) cache has been embedded into the Intel®  
Pentium® 4 processor, you do not have to take care of either SRAM chips  
or SRAM modules. The built-in second level cache in the Pentium® 4  
processor yields much higher performance than the external cache memo-  
ries. The cache size in the Intel® Pentium® 4 processor is 256 or 512 KB,  
depending on the type of CPU.  
1.11 CPU Installation  
The PCA-6185 provides socket 478 for an Intel® Pentium® 4 processor.  
The CPU on the board must have a fan or heat sink attached, to prevent  
overheating.  
Warning! Without a fan or heat sink, the CPU will overheat  
and cause damage to both the CPU and the  
motherboard.  
To install a CPU, first turn off your system and remove its cover. Locate  
the processor socket 478.  
1.  
Make sure the socket 478 lever is in the upright position. To raise  
the lever, pull it out to the side a little and raise it as far as it will go.  
2.  
Place the CPU in the empty socket. Follow the instructions that  
came with the CPU. If you have no instructions, complete the fol-  
lowing procedure. Carefully align the CPU so it is parallel to the  
socket and the notches on the corners of the CPU correspond with  
the notches on the inside of the socket. Gently slide the CPU in. It  
should insert easily. If it does not insert easily, pull the lever up a  
little bit more.

3.  
Press the lever down. The plate will slide forward. You will feel  
some resistance as the pressure starts to secure the CPU in the  
socket. This is normal and will not damage the CPU.

Chapter 2 Connecting Peripherals  
2.1 Primary (CN1) and Secondary (CN2) IDE Connec-  
tors  
CN2  
CN1  
You can attach up to four IDE (Integrated Drive Electronics) drives to the  
PCA-6185’s built-in controller. The primary (CN1) and secondary (CN2)  
connectors can each accommodate two drives.  
Wire number 1 on the cable is red or blue and the other wires are gray.  
Connect one end to connector CN1 or CN2 on the CPU card. Make sure  
that the red/blue wire corresponds to pin 1 on the connector (in the upper  
right hand corner). See Chapter 1 for help finding the connector.  
Unlike floppy drives, IDE hard drives can connect in either position on  
the cable. If you install two drives to a single connector, you will need to  
set one as the master and the other as the slave. You do this by setting the  
jumpers on the drives. If you use just one drive per connector, you should  
set each drive as the master. See the documentation that came with your  
drive for more information.  
Connect the first hard drive to the other end of the cable. Wire 1 on the  
cable should also connect to pin 1 on the hard drive connector, which is  
labeled on the drive circuit board. Check the documentation that came  
with the drive for more information.  
Connect the second hard drive to the remaining connector (CN2 or CN1),  
in the same way as described above.

Award BIOS Setup  
This chapter describes how to set the  
card’s BIOS configuration data.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 3 Award BIOS Setup  
3.1 Introduction  
Award’s BIOS ROM has a built-in setup program that allows users to  
modify the basic system configuration. This type of information is stored  
in battery-backed memory (CMOS RAM) so that it retains the setup  
information when the power is turned off.  
3.1.1 CMOS RAM auto-backup and restore  
The CMOS RAM is powered by an onboard button cell battery. When  
BIOS CMOS Setup has been completed, CMOS RAM data is automati-  
cally backed up to Flash ROM. If conditions in a harsh industrial enviro-  
ment cause a soft error, BIOS will recheck the data and automatically  
restore the original data for booting.  
Note:  
If you intend to change the CMOS setting without restoring  
the previous backup, you have to click on “DEL” within two  
seconds of the “CMOS checksum error....” display screen  
message appearing. Then enter the “Setup” screen to  
modify the data. If the “CMOS checksum error....” message  
appears again and again, please check to see if you need  
to replace the battery in your system.

3.2 Entering Setup  
Turn on the computer and check for the “patch code”. If there is a number  
assigned to the patch code, it means that the BIOS supports your CPU.  
If there is no number assigned to the patch code, please contact Advan-  
tech’s applications engineer to obtain an up-to-date patch code file. This  
will ensure that your CPU’s system status is valid.  
After ensuring that you have a number assigned to the patch code, press

SCSI Setup  
The PCA-6185 features an onboard  
SCSI interface. This chapter provides  
basic SCSI concepts and instructions  
for installing the software drivers with  
the SCSI driver disks CD included in  
your package.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 7 SCSI Setup  
7.1 Introduction  
The PCA-6185 is equipped with an Adaptec AIC-7902 single-chip PCI-  
to-SCSI host adapter which provides a dual channel Ultra 320 multitask-  
ing interface between your computer’s PCI bus and SCSI devices (disk  
drives, CD-ROM drives, scanners, tape backups, removable media  
drives, etc.). Ultra 320 is a new generation of SCSI technology that  
expands SCSI performance from 80 MBytes/sec to 320 MBytes/sec. Up  
to a total of 15 SCSI devices can be connected to each of the SCSI con-  
nectors.  
The AIC-7902 combines this Ultra 320 SCSI technology with Adaptec’s  
SpeedFlex™ technology. SpeedFlex allows the Adaptec SCSI card to be  
backwards compatible with previous generations of SCSI products, while  
allowing newer Ultra 320 SCSI devices to operate at the higher 320  
MBytes/sec rate.  
If you need to configure the SCSI, the onboard SCSI Select configuration  
utility allows you to change host adapter settings without opening the  
computer or handling the board. The SCSI Select utility also contains a  
utility to low-level format and verifies the disk media on your hard disk  
drives.  
Note:  
If any peripheral is running at SE mode, the Ultra 320  
SCSI segment will run at speeds up to 40 MBytes/  
sec only instead of 320 MBytes/sec.  
7.2 Understanding SCSI  
SCSI (pronounced “scuzzy”) stands for Small Computer Systems Inter-  
face. SCSI is an industry standard computer interface for connecting  
SCSI devices to a common SCSI bus.  
A SCSI bus is an electrical pathway that consists of a SCSI interface  
installed in a computer and one or more SCSI devices. SCSI cables are  
used to connect the devices to the SCSI interface. For the SCSI bus to  
function properly, a unique SCSI ID must be assigned to the SCSI inter-  
face and each SCSI device connected to it, and the SCSI bus must be  
properly terminated.  
PCA-6185 User’s Manual  
68  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
7.3 SCSI IDs  
Each device attached to the SCSI bus, as well as the SCSI controller  
itself, must be assigned a unique SCSI ID number from 0 to 15. A SCSI  
ID uniquely identifies each SCSI device on the SCSI bus and determines  
priority when two or more devices are trying to use the SCSI bus at the  
same time.  
Refer o the device’s documentation to set the SCSI ID. Here are some  
general guidelines for SCSI IDs:  
•
For internal SCSI devices, the SCSI ID usually is set by configur-  
ing a jumper on the device.  
For external SCSI devices, the SCSI ID usually is set with a swetch  
on the back of the device.  
SCSI ID numbers don’t have to sequential, as long as the SCSI con-  
troller and each device has a different number.  
For example, you can have an internal SCSI device with ID 0, and  
an external SCSI device with ID 6.  
SCSI ID 7 has the highest priority on the SCSI bus. The priority of  
the remianing IDs, in descending order, is 6 to 0, then 15 to 8.  
The on-boards SCSI interface is preset to SCSI ID 7 and should not  
be changed. This gives it the highest priority on the SCSI bus.  
Most internal SCSI hard disk drives come from the factory pre-set  
to SCSI ID 0.

•
If you have 8-bit (or Narrow) SCSI deveices, they must use SCSI  
IDs 0, 1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first SCSI  
hard disk drive.  
•
If you are booting your computer from a SCSI hards disk drive con-  
nected to the SCSI bus, the Boot SCSI ID setting in the  
SCSISelect utility must correspond to the SCSI ID of the deveice  
from which you are booting. By default, the Boot SCSI ID is set to 0. We  
recommend that you do not change this setting.  
•
In Windows© 95/98, you can use the Device Manager to determine  
which SCSI ID is assigned to each installed SCSI device.

7.4 Terminating the SCSI bus  
To ensure reliable communication on the SCSI bus, the ends of the SCSI  
bus must be properly terminated. This is accomplished when the device at  
the end of the each cable, or the end of the cable itself, has a terminator  
installed (or enabled). Terminators must be removed, or termination must  
be disabled, on devices between the ends of each cable.  
Since the method for terminating a SCSI device can vary widely, refer to  
the device’s documentation for instructions on how to enable or disable  
termination. Here are some general guidelines for termination:  
• Internal Ultra 320 and Ultra 2 SCSI devices come from the factory with  
termination disabled and cannot be changed. Proper termination for  
internal Ultra 320 and Ultra2 SCSI devices is provided by a 68-pin  
Internal LVD (low voltage differential) SCSI cable, which has a built-  
in terminator at its end.  
• Termination on non-Ultra 320 and Ultra2 internal SCSI devices usually  
is controlled by manually setting a jumper or a switch on the device, or  
by physically removing or installing one or more resistor modules on  
the device.  
• Termination on most external SCSI devices is controlled by installing  
or removing a SCSI terminator. However, termination on some exter-  
nal SCSI devices is enable or disabled by setting a swetich on the back  
of the SCSI device.  
• The last external Ultra 320 or Ultra2 SCSI device must be terminated  
with an LVD/SE (low voltage differential/single ended) terminator  
plug to ensure that the device will operate at its maximum speed. If you  
use a different kind of terminator plug, the data I/O rate will decrease.  
By default, termination on the SCSI controller itself is set to Automatic  
(the preferred method). We recommend that you do not change this  
default setting.  
7.5 Configuring the SCSI interface with SCSISelect  
SCSISelect, included with the CPU card, enables you to change SCSI set-  
tings without opening the computer. SCSISelect also enables you to low-  
level format or verify the disk media of your SCSI hard disk drives. The  
following table lists the available and default settings for each SCSISelect  
option.  
Note:  
The default settings are appropriate for most sys-

SCSI Bus Interface Definitions  
• Host Adapter SCSI ID-(Default: 7) Sets the SCSI ID for the SCSI card.  
The Adaptec SCSI Card is set at 7, which gives t the highest priority on  
the SCSI bus. We recommend that you do not change this setting.  
• SCSI Parity Checking-(Default: Enabled) When set to Enabled, verifies  
the accuracy of data transfer on the SCSI bus. Leave this setting enabled  
unless any SCSI device connected to the Adaptec SCSI Card does not  
support SCSI parity.  
• Host Adapter SCSI Termination-(Default: Automatic) Determines the  
termination setting for the SCSI card. The default setting for both the  
LVD/SE (low voltage differential/single ended) connectors and SE con-  
nectors is Automatic, which allows the SCSI card to adjust the termina-  
tion as needed depending on the configuration of the connected SCSI  
devices. We recommend that you do not change these settings.  
Boot Device Options  
• Boot SCSI ID-(Default: 0) Specifies the SCSI ID of your boot device.  
We recommend that you dono t change the default setting.  
• Boot LUN Number-(Default: 0) Specifies which LUN (Logical Unit  
Number) to boot from on your boot device. This setting is not valid unless  
Multiple LUN Support is Enabled.  
SCSI Device Configuration  
SCSI Device Configuration options can be set individually for each con-  
nected SCSI device.  
Note:  
To configure settings for a SCSI device, you must  
know it’s SCSI ID  
• Sync Transfer Rate-(Default: 320) Determines the maximum synchro-  
nous data transfer rate that the SCSI card supports. Use the mazimum  
value of 320 MBytes/sec.  
73  
Chapter7  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
• Initiate Wide Negotiation-(Default: Yes) When set to Yes, the SCSI  
card attempts 16-bit data transfer (wide negotiation.) When set to No, the  
SCSI card uses 8-bit data transfer unless the SCSI device requests wide  
negotiation.  
Note:  
Set Initiate Wide Negotiation to NO if you are using  
an 8-bit SCSI device that hangs or exhibits other per-  
formance problems with 16-bit data transfer rate  
enabled.  
• Enable Disconnection-(Default: Yes) When set to Yes, allows the  
SCSI device to disconnect from the SCSI bus. Leave the setting at Yes if  
two or more SCSI device is connected, changing the setting to No results  
in slightly better performance.  
• Send Start Unit Command-(Default: Yes) When set to Yes, the Start  
Unit Command is sent to the SCSI device at bootup.  
The following three options have no effect if the SCSI Card BIOS is dis-  
abled. (The SCSI Cards BIOS is normally enabled by default.)  
• Enable Write Back Cache-(Default: N/C) Can be used to enable or  
disable the write-back cache on SCSI disk drives connected to the host  
adapter. Leave this option at its default setting of N/C (no change), which  
usually allow for optimum drive performance.  
• BIOS Multiple LUN Support-(Default: No) Leave this setting at No if  
the device does not have multiple Logical Unit Numbers (LUNs.) When  
set to Yes, the SCSI card BIOS provides boot support for a SCSI device  
with multiple LUNs (for example, a CD “juke box” device in which  
mulitple CDs can be accessed simultaneously.)  
• Include in BIOS Scan-(Default: Yes) When set to Yes, the SCSI card  
BIOS includes the device as part of its BIOS scan at bootup.  
Advanced Configuration Options  
Note:  
Do not change the Advanced Configuration Options  
unless absolutely necessary.  
• Reset SCSI Bus at IC Initialization-(Default: Enabled) When set to  
Enabled, the SCSI card generates a SCSI bus reset during its power-on  
initialization and after a hard reset.  
• Display <Ctrl> <A> Messages during BIOS Initialization-(Default:  
Enabled) When set to Enabled, the SCSI card BIOS displays the Press  
<Ctrl> <A> for SCSISelect (TM) Utility! message on your screen during  
PCA-6185 User’s Manual

system bootup. If this setting disabled, you can still invoke the SCSISe-  
lect Utility by pressing <Ctrl> <A> after the SCSI card BIOS banner  
appears.  
• Extended BIOS Translation for DOS Drives > 1 GByte-(Default:  
Enabled) When set to Enabled, provides an extended translation scheme  
for SCSI hard disks with capacities greater than 1 GByte. This setting is  
necessary only for MS-DOS 5.0 or above; it is not required for other  
operating systems, such as NetWare of UNIX.  
Caution: Changing the translation scheme destroys all data on  
the drive. Bue sure to back your disk drives before  
changing the translation scheme.  
Use the MS-DOS Fdisk command to partition a disk laster than 1GByte  
controlled by the SCSI card BIOS, when using DOS, Windows 3.1.x, ro  
Windows 95/98.  
• Verbose/Silent Mode-(Default: Verbose) When set to Verbose, the  
SCSI card BIOS displays the host adapter model on the screen during  
sustem buildup. When set to Silent, the message is not displayed during  
bootup.  
• Host Adapter BIOS (Configuration Utility Reserves BIOS Space)-  
(Default: Enabled) Enables or disables the SCSI card  
• Leave at Enabled to allow the SCSI card BIOS to scan and ini-  
tialize all SCSI devices.  
• Set to Disabled: Not scan if the devices on the SCSI bus (for  
example, CD-ROM drives) are controlled by software drivers and do not  
need the BIOS, and you do not want the BIOS to scan the SCSI bus.  
• Set to Disabled: Scan Bus if you do not need the BIOS, but you  
want it to scan the SCSI devices on the bus and you need to spin up the  
devices.  
The following four options have no effect when the SCSI Card BIOS is  
disabled. (The SCSI Card BIOS is normally enabled by default.)  
• Domain Validation—(Default: Enabled) Determines the optimal trans-  
fer rate for each device on the SCSI bus and sets transfer rates accord-  
ingly. Displays the resulting data transfer rate.  
75  
Chapter7  
Download from Www.Somanuals.com. All Manuals Search And Download.  
• Support Removable Disks Under BIOS as Fixed Disks—(Default:  
Disabled) Determines which removable-media drives are supported by  
the SCSI card BIOS. Choices are as follows:  
• Disabled— No removable-media drives are treated as hard disk  
drives. Software drivers are required because the drives are not  
controlled by the BIOS.  
• Boot Only—Only the removable-media drive designated as the  
boot device is treated as a hard disk drive.  
• All Disks—All removable-media drives supported by the BIOS  
are treated as hard disk drives.  
Caution: You may lose data if you remove a removable-media  
cartridge from a SCSI drive controlled by the SCSI  
card BIOS while the drive is on. If you want to be  
able to remove the media while the drive is on, install  
the removable-media software driver and set Sup-  
port Removable Disks Under BIOS as Fixed Disks to  
Disabled.  
• BIOS Support for Bootable CD-ROMs—(Default: Enabled) When  
set to Enabled, the SCSI card BIOS allows the computer to boot from a  
CD-ROM drive.  
• BIOS Support for Int 13 Extensions—(Default: Enabled) When set to  
Enabled, the SCSI card BIOS supports Int 13h extensions as required by  
Plug-and-Play. The setting can be either enabled or disabled if your sys-  
tem is not Plug-and-Play.

7.8 Using SCSI Disk Utilities  
To access the SCSI disk utilities, follow these steps:  
1.  
Select the SCSI Disk Utilities option from the menu that appears  
after starting SCSISelect. SCSISelect scans the SCSI bus (to deter-  
mine the devices installed) and displays a list of all SCSI IDs and  
the devices assigned to each ID.  
2.  
3.  
Use the arrow keys to move the cursor to a specific ID and device,  
then press Enter.  
A small menu appears, displaying the options Format Disk and Ver-  
ify Disk Media.  
• Format Disk—Allows you to perform a low-level format on a hard  
disk drive. Most SCSI disk devices are preformatted at the factory and do  
not need to be formatted again.  
Caution: A low-level format destroys all data on the drive. Be  
sure to back up your data before performing this  
operation. You cannot abort a low-level format once it  
is started.  
• Verify Disk Media—Allows you to scan the media of a hard disk drive  
for defects. If the utility finds bad blocks on the media, it prompts you to  
reassign them; if you select yes, those blocks are no longer used. Pressing  
Esc at any time aborts the utility.  
7.9 Installation under Windows NT/Windows 2000

Programming the  
Watchdog Timer  
The PPC-123 is equipped with a watch-  
dog timer that resets the CPU or gener-  
ates an interrupt if processing comes to  
a standstill for any reason. This feature  
ensures system reliability in industrial  
standalone or unmanned environments.

Appendix A Programming the Watchdog  
Timer  
A.1 Programming the Watchdog Timer  
To program the watchdog timer, you must write a program which writes I/  
O port address 444 (hex). The output data is a time interval value. The  
value range is from 01 (hex) to 3E (hex), and the related time interval is  
from 1 sec. to 62 sec.  
Data Time Interval  
01 1 sec.  
02 2 sec.  
03 3 sec.  
04 4 sec.  
•
•
•
•
•
•
3E 62 sec.  
After data entry, your program must refresh the watchdog timer by rewrit-  
ing the I/O port 444 (hex) while simultaneously setting it. When you want  
to disable the watchdog timer, your program should read I/O port 43  
(hex).
