III. INSTALLATION
Installation Steps
Before using your computer, you must complete the following steps:
1. Set Jumpers on the Motherboard
2. Install System Memory Modules
3. Install the Central Processing Unit (CPU)
4. Install Expansion Cards
5. Connect Ribbon Cables, Cabinet Wires, and Power Supply
6. Setup the BIOS Software
1. Jumpers
Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the motherboard. See motherboard layout for locations of jumpers. The
jumper settings will be described numerically, such as [----], [1-2], [2-3] for no con-
nection, connect pins 1&2, and connect pins 2&3, respectively. A “1” is written be-
sides pin 1 on jumpers with three pins. The jumpers will also be shown graphically
such as
to connect pins 1&2 and
to connect pins 2&3. Jumpers with
for Open (Off). For manufac-
two pins will be shown as
for Short (On) and
turing simplicity, the jumpers may be sharing pins from other groups. Use the dia-
grams in this manual instead of following the pin layout on the board. Settings with
two jumper numbers require that both jumpers be moved together. To connect the
pins, simply place a plastic jumper cap over the two pins as diagrammed.
WARNING! Computer motherboards, baseboards and components, such as SCSI
cards, contain very delicate Integrated Circuit (IC) chips. To protect them against
damage from static electricity, you should follow some precautions whenever you
work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a
metal object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or
connectors, or other components.
4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

Jumper Settings
1. Clear Real Time Clock (RTC) RAM (CLRTC)
The CMOS RAM is powered by the onboard button cell battery. To clear the
RTC data: (1) Turn off your computer and unplug its AC power, (2) Short the
two solder points labeled CLRTC, (3) Turn on your computer, (4) Hold down
<Delete> during bootup and enter BIOS setup to re-enter user preferences.
Short the solder points to clear CMOS
P2B-D/DS Real Time Clock RAM (CLRTC)
2. Keyboard Power Up (KBPK)
This allows you to disable or enable the keyboard power up function. Set to
Enable if you want to use your keyboard (by pressing <Spacebar>) to power up
your computer. This feature requires an ATX power supply that can supply at
least 300mAon the +5VSB lead and the newACPI BIOS support. The default is
set to Disable because not all computers have the appropriate ATX power sup-
ply. Your computer will not function if you set this to Enable and if you do not
have the right ATX power supply.

3. CPU Bus Frequency (FS0, FS1, FS2)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
440BX AGPset. This allows the selection of the CPU’s External frequency (or BUS
Clock). The BUS Clock multiplied by the BUS Ratio equals the CPU’s Internal fre-
quency (the advertised CPU speed).
4. CPU Core:BUS Frequency Multiple (BF0, BF1, BF2, BF3)
This option sets the frequency ratio between the Internal frequency of the CPU
and the CPU’s External frequency. These must be set in conjunction with the
CPU Bus Frequency.

2. System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Three sockets
are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random
Access Memory (SDRAM) of either 8, 16, 32, 64, 128, or 256MB to form a memory
size between 8MB and 1GB. One side (with memory chips) of the DIMM takes up
one row on the motherboard.
To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a
DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip) and make
the proper settings through “Chipset Features Setup” in IV. BIOS SOFTWARE.
Memory speed setup is recommended through SDRAM Configuration under “Chipset
Features Setup”.
IMPORTANT (see General DIMM Notes below)
•
SDRAMs used must be compatible with the current Intel PC100 SDRAM
specification.
Install memory in any combination as follows:

General DIMM Notes
•
Use only PC100-compliant DIMMs. This motherboard operates at 100MHz, thus most
systems will not even boot if non-compliant modules are used because of the strict tim-
ing issues involved under this speed.
•
•
Two possible memory chips are supported: SDRAM with and without ECC.
SDRAM chips are generally thinner with higher pin density than EDO (Extended Data
Output) chips.
•
•
•
BIOS shows SDRAM memory on bootup screen.
8 chips/side modules do not support ECC, only 9 chips/side modules support ECC.
Single-sided DIMMs come in 16, 32, 64, 128MB; double-sided come in 32, 64, 128, 256MB.

Insert the module(s) as shown. Because the number of pins is different on either side
of the breaks, the module will only fit in the orientation as shown. DRAM SIMM
modules have the same pin contacts on both sides. SDRAM DIMMs have different
pin contacts on each side and therefore have a higher pin density.

4. Expansion Cards
WARNING! Unplug your power supply when adding or removing expansion
cards or other system components. Failure to do so may cause severe damage to
both your motherboard and expansion cards.
Expansion Card Installation Procedure
1. Read the documentation for your expansion card and make any necessary
hardware or software settings for your expansion card, such as jumpers.
2. Remove your computer system’s cover and the bracket plate on the slot you
intend to use. Keep the bracket for possible future use.
3. Carefully align the card’s connectors and press firmly.
4. Secure the card on the slot with the screw you removed above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary
(such as IRQ xx Used By ISA: Yes in PNP AND PCI SETUP)
7. Install the necessary software drivers for your expansion card.
Assigning IRQs for Expansion Cards
Some expansion cards need to use an IRQ to operate. Generally, an IRQ must be
exclusively assigned to one use. In a standard design, there are 16 IRQs available
but most of them are already in use, leaving 6 IRQs free for expansion cards. If your
motherboard has audio onboard, an extra 3 IRQs will be used, leaving 3 IRQs free.
Both ISA and PCI expansion cards may require to use IRQs. System IRQs are avail-
able to cards installed in the ISA expansion bus first, then any remaining IRQs are
available to PCI cards. Currently, there are two types of ISAcards. The original ISA
expansion card design, now referred to as legacy ISA cards, requires that you con-
figure the card’s jumpers manually and then install it in any available slot on the ISA
bus. You may use the Microsoft Diagnostics (MSD.EXE) utility located in the Win-
dows directory to see a map of your used and free IRQs. If you use Windows 95, the
Resources tab under Device Manager displays the resource settings being used by
a particular device (to gain access, double-click the System icon under the Control
Panel program). Ensure that no two devices share the same IRQs or your computer
will experience problems when those two devices are in use at the same time.
24
ASUS P2B-D/P2B-DS User’s Manual
III. INSTALLATION
To simplify this process, this motherboard complies with the Plug and Play (PnP)
specification, which was developed to allow automatic system configuration when-
ever a PnP-compliant card is added to the system. For PnP cards, IRQs are assigned
automatically from those available.
If the system has both legacy and PnP ISA cards installed, IRQs are assigned to PnP
cards from those not used by legacy cards. The PCI and PNP configuration section
of the BIOS setup utility can be used to assign which IRQs are being used by legacy
cards. For older legacy cards that do not work with the BIOS, you may contact your
vendor for an ISA Configuration Utility.
An IRQ number is automatically assigned to PCI expansion cards after those used
by legacy and PnP ISA cards. In the PCI bus design, the BIOS automatically assigns
an IRQ to a PCI slot that contains a card requiring an IRQ. To install a PCI card, you
need to set the INT (interrupt) assignment. Since all the PCI slots on this mother-
board use an INTA #, set the jumpers on your PCI cards to INT A.
Assigning DMA Channels for ISA Cards
Some ISAcards, both legacy and PnP, may also need to use a DMA(Direct Memory
Access) channel. DMA assignments for this motherboard are handled the same way
as the IRQ assignment process described earlier. You can select a DMA channel in
the PCI and PnP configuration section of the BIOS Setup utility.
IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy
ISA cards (under PNPAND PCI SETUP of the BIOS SOFTWARE, choose Yes in IRQ
xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).
ISA Cards and Hardware Monitor
The onboard hardware monitor uses the address 290H-297H so legacy ISA cards
must not use this address or else conflicts will occur.
Accelerated Graphics Port
This motherboard provides an accelerated graphics port (AGP) slot to support a new
generation of graphics cards with ultra-high memory bandwidth, such as the ASUS

6. BIOS Setup
The motherboard supports two programmable Flash ROM chips: 5-Volt and 12-
Volt. Either of these memory chips can be updated when BIOS upgrades are re-
leased. Use the Flash Memory Writer utility to download the new BIOS file into the
ROM chip as described in detail in this section.
All computer motherboards provide a Setup utility program for specifying the sys-
tem configuration and settings. If your motherboard came in a computer system, the
proper configuration entries may have already been made. If so, invoke the Setup
utility, as described later, and take note of the configuration settings for future refer-
ence; in particular, the hard disk specifications.
If you are installing the motherboard, reconfiguring your system or you receive a
Run Setup message, you will need to enter new setup information. This section
describes how to configure your system using this utility.
The BIOS ROM of the system stores the Setup utility. When you turn on the com-
puter, the system provides you with the opportunity to run this program. This ap-
pears during the Power-On Self Test (POST). Press <Delete> to call up the Setup
utility. If you are a little bit late pressing the mentioned key(s), POST will continue
with its test routines, thus preventing you from calling up Setup. If you still need to
call Setup, reset the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressing
the Reset button on the system case. You can also restart by turning the system off
and then back on again. But do so only if the first two methods fail.
When you invoke Setup, the CMOS SETUP UTILITY main program screen will
appear with the following options:

Load Defaults
The “Load BIOS Defaults” option loads the minimum settings for troubleshooting.
“Load Setup Defaults”, on the other hand, is for loading optimized defaults for
regular use. Choosing defaults at this level, will modify all applicable settings.
A section at the bottom of the above screen displays the control keys for this screen.
Take note of these keys and their respective uses. Another section just below the

Standard CMOS Setup
The “Standard CMOS Setup” option allows you to record some basic system hard-
ware configuration and set the system clock and error handling. If the motherboard
is already installed in a working system, you will not need to select this option
anymore. However, if the configuration stored in the CMOS memory on the board
gets lost or damaged, or if you change your system hardware configuration, you will
need to respecify the configuration values. The configuration values usually get lost
or corrupted when the power of the onboard CMOS battery weakens.
The preceding screen provides you with a list of options. At the bottom of this screen
are the control keys for this screen. Take note of these keys and their respective uses.
User-configurable fields appear in a different color. If you need information on the
selected field, press <F1>. The help menu will then appear to provide you with the
information you need. The memory display at the lower right-hand side of the screen
is read-only and automatically adjusts accordingly.

NOTE: You can bypass the date and time prompts by creating anAUTOEXEC.BAT
file. For information on how to create this file, please refer to the MS-DOS manual.
Hard Disks
This field records the specifications for all non-SCSI hard disk drives installed in
your system. The onboard PCI IDE connectors provide Primary and Secondary
channels for connecting up to four IDE hard disks or other IDE devices. Each chan-
nel can support up to two hard disks; the first of which is the “master” and the
second is the “slave”.
Specifications for SCSI hard disks need not to be entered here since they operate
using device drivers and are not supported bythe BIOS. If you install other SCSI
controller cards, refer to their respective documentations on how to install the re-
quired SCSI drivers.
For IDE hard disk drive setup, you can:
•
•
Use the Auto setting for detection during bootup.
Use the IDE HDD AUTO DETECTION in the main menu to automatically
enter the drive specifications.
•
Enter the specifications yourself manually by using the “User” option.
The entries for specifying the hard disk type include CYLS (number of cylinders),
HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ
(landing zone), SECTOR (number of sectors) and MODE. The SIZE field auto-
matically adjusts according to the configuration you specify. The documentation
that comes with your hard disk should provide you with the information regarding
the drive specifications.
The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI
drives. This entry provides three options: Normal, Large, LBA, or Auto (see below).
Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to
LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow
larger IDE hard disks; set it to Large for drives over 528MB that do not support
LBA. Large type of drive can only be used with MS-DOS and is very uncommon.
Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootup
For each field: Primary Master, Primary Slave, Secondary Master, and Secondary
Slave, you can select Auto under the TYPE and MODE fields. This will enable auto
detection of your IDE hard disk during bootup. This will allow you to change your
hard disks (with the power off) and then power on without having to reconfigure
your hard disk type. If you use older hard disks that do not support this feature, then
you must configure the hard disk in the standard method as described earlier by the
“User” option.
NOTE: After the IDE hard disk drive information has been entered into BIOS, new
IDE hard disk drives must be partitioned (such as with FDISK) and then formatted
before data can be read from and write on. Primary IDE hard disk drives must have
its partition set to active (also possible with FDISK).
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.
Drive A / Drive B (None)
These fields record the types of floppy disk drives installed in your system. The
available options for drives A and B are: 360KB, 5.25 in.; 1.2MB, 5.25 in.; 720KB,
3.5 in.; 1.44MB, 3.5 in.; 2.88MB, 3.5 in.; None
To enter the configuration value for a particular drive, highlight its corresponding
field and then select the drive type using the left- or right-arrow keys.
Floppy 3 Mode Support (Disabled)
This is the Japanese standard floppy drive. The standard stores 1.2MB in a 3.5inch

CPU Internal Core Speed (350MHz)
This function is reserved for future use and is currently disabled.
Boot Virus Detection (Enabled)
This field allows you to set boot virus detection, ensuring a virus-free boot sector.
This new antivirus solution is unlike native BIOS tools, which offer limited virus
protection typically by write-protecting the partition table. With this new solution,
your computer is protected against boot virus threats earlier in the boot cycle, that is,
before they have a chance to load into your system. This ensures your computer
boots to a clean operating system. The system halts and displays a warning message
when it detects a virus. If this occurs, you can either allow the operation to continue
or use a virus-free bootable floppy disk to restart and investigate your system. Be-
cause of conflicts with new operating systems, for example, during installation of
new softwares, you may have to set this to Disabled to prevent write errors.

CPU Level 1 Cache / CPU Level 2 Cache (Enabled)
These fields allow you to choose from the default of Enabled or choose Disabled to
turn on or off the CPU’s Level 1 and Level 2 built-in cache.
CPU Level 2 Cache ECC Check (Disabled)
This function controls the ECC check capability in the CPU level 2 cache.
BIOS Update (Enabled)
This functions as an update loader integrated into the BIOS to supply the processor
with the required data. The BIOS will load the update on all processors during
system bootup in the default position of Enabled.
Quick Power On Self Test (Enabled)
This field speeds up the Power-On Self Test (POST) routine by skipping retesting a
second, third, and forth time. Setup default setting for this field is Enabled. A
complete test of the system is done on each test.
HDD Sequence SCSI/IDE First (IDE)
When using both SCSI and IDE hard disk drives, IDE is always the boot disk using
drive letter C (default setting of IDE). This new feature allows a SCSI hard disk
drive to be the boot disk when set to SCSI. This allows multiple operating systems
to be used on both IDE and SCSI drives or the primary operating system to boot
using a SCSI hard disk drive.
Boot Sequence (A,C)
This field determines where the system looks first for an operating system. Options
are A,C; A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; C only; LS/ZIP, C; and C,A. The
setup default setting, A, C, is to check first the floppy disk and then the hard disk drive.
Boot Up Floppy Seek (Disabled)
When enabled, the BIOS will seek drive A once.
Floppy Disk Access Control (R/W)
This allows protection of files from the computer system to be copied to floppy
disks by allowing the setting of Read Only to only allow reads from the floppy disk
drive but not writes. The setup default R/W allows both reads and writes.
IDE HDD Block Mode Sectors (HDD MAX)
This field enhances hard disk performance by making multi-sector transfers instead
of one sector per transfer. Most IDE drives, except older versions, can utilize this
feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32.

Security Option (System)
When you specify a Supervisor Password and/or User Password (explained later in
this section), the Security Option field determines when the system prompts for the
password. The default setting is System, where the system prompts for the User
Password every time you start your system. The other option is Setup, where the
system goes through its startup routine unless the Setup utility is called, when the
system prompts for the Supervisor Password.
PS/2 Mouse Function Control (Auto)
The default of Auto allows the system to detect a PS/2 mouse on bootup. If detected,
IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cards
if a PS/2 mouse is not detected. Enabled will always reserve IRQ12, whether on
bootup a PS/2 mouse is detected or not.
PCI/VGA Palette Snoop (Disabled)
Some display cards that are nonstandard VGAsuch as graphics accelerators or MPEG
Video Cards may not show colors properly. The setting Enabled should correct this
problem. Otherwise leave this on the setup default setting of Disabled.
OS/2 Onboard Memory > 64M (Disabled)
When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to set this option to Enabled otherwise leave this on Disabled.
......................................................................................................................................
Video ROM BIOS Shadow (Enabled)
This field allows you to change the video BIOS location from ROM to RAM. Relo-
cating to RAM enhances system performance, as information access is faster than
the ROM.
C8000-CBFFF to DC000-DFFFF (Disabled)
These fields are used for shadowing other expansion card ROMs. If you install
other expansion cards with ROMs on them, you will need to know which addresses
the ROMs use to shadow them specifically. Shadowing a ROM reduces the memory
available between 640K and 1024K by the amount used for this purpose.
Boot Up NumLock Status (On)
This field enables users to activate the Number Lock function upon system boot.
Typematic Rate Setting (Disabled)
When enabled, you can set the two typematic controls listed next. Setup default
setting is Disabled.
Typematic Rate (Chars/Sec) (6)
This field controls the speed at which the system registers repeated keystrokes.
Options range from 6 to 30 characters per second. Setup default setting is 6; other
settings are 8, 10, 12, 15, 20, 24, and 30.

Memory Hole At 15M–16M (Disabled)
Enabling this feature reserves 15MB to 16MB memory address space to ISA expan-
sion cards that specifically require this setting. This makes the memory from 15MB
and up unavailable to the system. Expansion cards can only access memory up to
16MB. The default is Disabled.

Parallel Port Mode (ECP+EPP)
This field allows you to set the operation mode of the parallel port. The setting
Normal, allows normal-speed operation but in one direction only; EPP allows bidi-
rectional parallel port operation at maximum speed; ECP allows the parallel port to
operate in bidirectional mode and at a speed faster than the maximum unidirectional
data transfer rate; ECP+EPP allows normal speed operation in a two-way mode.

This selection is available only if you select ECP or ECP+EPP in the Parallel Port
Mode. Select either DMA Channel 1, 3, or Disable.
UART2 Use Infrared (Disabled)
When enabled, this field activates the onboard infrared feature and sets the second
serial UART to support the infrared module connector on the motherboard. If your
system already has a second serial port connected to the onboard COM2 connector, it
will no longer work if you enable the infrared feature. By default, this field is set to

leave ISA MEM Block BASE to its default setting of No/ICU.
Onboard AHA BIOS (Auto)
The default uses Auto settings for the onboardAdaptec 7890 SCSI BIOS. If you do
not want to use the onboard Adaptec 7890 SCSI BIOS, choose Disabled.
ONB AHA BIOS First (No)
This field allows giving priority to the onboard SCSI BIOS for SCSI functions over
other SCSI controllers. The default is No.
ONB SCSI SE Term. (Enabled)
This allows you to enable or disable the onboard termination for single-ended (SE)
devices, such as scanners, CD-ROMS, or tape drives. The default is Enabled.
ONB SCSI LVD Term. (Enabled)
This allows you to enable or disable the onboard termination for Ultra2 devices,
such as disk drives, using low voltage differential (LVD) technology. LVD allows
the onboard SCSI chipset to support a maximum of 15 devices on a 12m cable, a
fourfold increase over UltraSCSI cable length. In a point-to-point configuration, the
cabling can be extended up tp 25m. This increased length allows greater flexibility
in your system configuration, especially in RAID and clustering applications. The
default for this field is Enabled.
USB IRQ (Enabled)
Enabled reserves an IRQ# for the USB to work, Disabled does not allow the USB to
have an IRQ# and therefore prevents the USB from functioning. If you are not using
any USB devices, you may set this feature to Disabled to save an extra IRQ# for
expansion cards.

Supervisor Password and User Password
These two options set the system passwords. “Supervisor Password” sets a pass-
word that will be used to protect the system and the Setup utility; “User Password”
sets a password that will be used exclusively on the system. By default, the system
comes without any passwords. To specify a password, highlight the type you want
and then press <Enter>. Apassword prompt appears on the screen. Taking note that
the password is case sensitive, and can be up to 8 alphanumeric characters long, type
in your password and then press <Enter>. The system confirms your password by
asking you to type it again. After setting a password, the screen automatically re-
verts to the main screen.
To implement password protection, specify in the “Security Option” field of the
BIOS Features Setup screen when the system will prompt for the password. If you
want to disable either password, press <Enter> instead of entering a new password
when the “Enter Password” prompt appears. A message confirms the password has
been disabled.

IDE HDD Auto Detection
This “IDE HDD Auto Detection” option detects the parameters of an IDE hard disk
drive, and automatically enters them into the Standard CMOS Setup screen.
Up to four IDE drives can be detected, with parameters for each listed inside the
box. To accept the optimal entries, press <Y> or else select from the numbers dis-
played under the OPTIONS field (2, 1, 3 in this case); to skip to the next drive, press
<N>. If you accept the values, the parameters will appear listed beside the drive
letter on the screen. The process then proceeds to the next drive letter. Pressing
<N> to skip rather than to accept a set of parameters causes the program to enter
zeros after that drive letter.
Remember that if you are using another IDE controller that does not feature En-
hanced IDE support for four devices, you can only install two IDE hard disk drives.
Your IDE controller must support the Enhanced IDE features in order to use Drive E
and Drive F. The onboard PCI IDE controller supports Enhanced IDE, with two
connectors for connecting up to four IDE devices. If you want to use another con-
troller that supports four drives, you must disable the onboard IDE controller in the
Chipset Features Setup screen.
When auto-detection is completed, the program automatically enters all entries you
accepted on the field for that drive in the Standard CMOS Setup screen. Skipped
entries are ignored and are not entered in the screen.
If you are auto-detecting a hard disk that supports the LBA mode, three lines will
appear in the parameter box. Choose the line that lists LBA for an LBA drive. Do
not select Large or Normal.
The auto-detection feature can only detect one set of parameters for a particular IDE
hard drive. Some IDE drives can use more than one set. This is not a problem if the
drive is new and empty.

VI. DESKTOP MANAGEMENT
Desktop Management Interface (DMI)
Introducing the ASUS DMI Configuration Utility
This motherboard supports DMI within the BIOS level and provides a DMI Con-
figuration Utility to maintain the Management Information Format Database (MIFD).
DMI is able to auto-detect and record information pertinent to a computer’s system
such as the CPU type, CPU speed, and internal/external frequencies, and memory
size. The onboard BIOS will detect as many system information as possible and
store those collected information in a 4KB block in the motherboard’s Flash EPROM
and allow the DMI to retrieve data from this database. Unlike other BIOS software,
the BIOS on this motherboard uses the same technology implemented for Plug and
Play to allow dynamic real-time updating of DMI information versus creating a new
BIOS image file and requiring the user to update the whole BIOS. This DMI Con-
figuration Utility also allows the system integrator or end user to add additional
information into the MIFD such as serial numbers, housing configurations, and ven-
dor information. Those information not detected by the motherboard BIOS and has
to be manually entered through the DMI Configuration Utility and updated into the
MIFD. This DMI Configuration Utility provides the same reliability as PnP updat-
ing and will prevent the refreshing failures associated with updating the entire BIOS.
System Requirements
The DMI Configuration Utility (DMICFG2.EXE) must be used in real mode in
order for the program to run, the base memory must be at least 180K. Memory
managers like HIMEM.SYS (required by windows) must not be installed. You can
boot up from a system diskette without AUTOEXEC.BAT and CONFIG.SYS files,
“REM” HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass
your AUTOEXEC.BAT and CONFIG.SYS files.

Q: What is Wake-On-LAN ?
A: The Wake-On-LAN feature provides the capability to remotely power on sys-
tems supporting Wake-On-LAN by simply sending a wake-up frame. With this
feature, remotely uploading/downloading data to/from systems during off-peak
hours will be feasible.
Q: What can Wake-On-LAN do for you ?
A: Wake-On-LAN is a remote management tool with advantages that can reduce
system management workload, provide flexibility to the system administrator’s
job, and then of course save you time-consuming efforts and costs.
Q: What components does Wake-On-LAN require to be enable?
A: To enable Wake-On-LAN function, your system requires Ethernet LAN adapter
card that can activate Wake-On-LAN function, a client with Wake-On-LAN capa-
bility, and software such as LDCM Rev. 3.10 or up that can trigger wake-up frame.

Format Disk - low-level formats your SCSI hard disks. In general, SCSI hard disks
have already been low-level formatted when you get them, so you generally do not
need to use this function.
Verify Media - scans the selected drive media for defects, notifies you of any de-
fects found and gives you the option of reassigning bad blocks so that data will not
be written to them. This utility is only necessary if you suspect that your SCSI disk
drive has a problem.

Welcome to Adaptec EZSCSIVI, ADAPTEC EZ-SCSI UTILITY 4.03. Adaptec
®
EZSCSI gives you what you need to use DOS, Windows 3.1x, or Windows for
Workgroups3.1x.
Note: TheADAPTEC EZ-SCSI UTILITYdoes not provide drivers for Windows®95
and WindowsNT™.
Quick Start Instructions
First, install SCSI devices (see the hardware documentation for details). Then fol-
low the instructions for your operating system software in one of the following sec-
tions. We recommend that after you install Adaptec EZSCSI, you run SCSITutor to
learn more about the features of SCSI.
Windows95 or WindowsNT
If you want to install Windows95 or WindowsNT on a new computer system, you

Troubleshooting Tips
SCSI Device Troubleshooting
Review this checklist if your newly-installed SCSI disk drives, CDROM drives, and
other devices do not seem to work properly:
• Be sure that termination is correctly set for all devices on the SCSI bus, as
described in your host adapter documentation.
• Be sure there are no hardware conflicts such as devices in your computer try-
ing to use the same interrupts (IRQs) or DMA channels.
• Be sure the cables connecting the external and internal SCSI devices and the
host adapter are attached securely. Also be sure the pin-1 orientation is correct
for internal cables. See the host adapter documentation for more information.
• Be sure that each SCSI device connected to the host adapter has a unique SCSI ID.
• Be sure CD-ROM drives and other SCSI devices are attached to a power source
and are turned ON.
Windows95/WindowsNT Troubleshooting
What is a miniport driver, and how do I make sure that the miniport driver is
installed correctly?
Miniport drivers are a new kind of 32bit protect mode device driver used by Win-
dows95 and WindowsNT to control host adapters and other kinds of devices. Win-
dows95 and WindowsNT include a set of miniport drivers for various types of SCSI
host adapters. The host adapter miniport driver is automatically installed and con-
figured during Windows95 and WindowsNT installation if your host adapter is al-
ready installed. To make sure the driver is installed correctly in systems running
Windows95, open the Control Panel, double-click on System, and click the Device
Manager tab. Then double-click the SCSI Controllers icon; you should see the model
name of the SCSI host adapter(s) installed in your system.
What if there is no SCSI controllers icon under Device Manager, or the model
name of the SCSI chipset does not appear under Device Manager?
If the SCSI controllers icon or your host adapter’s model name do not appear, open
Control Panel and double-click the Add New Hardware icon. Let Windows search
for the host adapter by selecting Yes on the second screen of theAdd New Hardware
Wizard.
If Windows does not detect the host adapter, run the Add New Hardware Wizard
again. This time, select No on the second screen of the wizard, then select SCSI
controllers on the next screen. Select the name of your host adapter when it appears.
68
ASUS P2B-D/P2B-DS User’s Manual
IX. ADAPTEC EZ-SCSI
If the name of your SCSI chipset does not appear, you may be able to find its
miniport driver on the Windows95 CD-ROM. Follow these steps:
1 Place the Windows95 CD-ROM in your CDROM drive and run the Add New
Hardware wizard.
2 Select No on the second screen, and select SCSI controllers on the next screen.
3 Click on the Have Disk button, then click the Browse button.
4 Look in the \drivers\storage directory of the CDROM and select the name of
your SCSI host adapter if it appears.
What if a yellow exclamation point or a red X appears in Device Manager in
front of my host adapter?
This means there is some kind of resource problem. First, see if the names of any
host adapters appear that are not actually installed in your computer. If so, select the
name and click Remove. If a red X appears in front of your host adapter name,
remove all the host adapter references under SCSI Controllers and run Add New
Hardware, as described in the previous question/answer. If a yellow exclamation
point appears in front of your host adapter name, the resources that the driver uses
probably do not match the resources used by the hardware. Double-click the host
adapter name, then click on the Resource tab. Deselect the Use automatic settings
box and edit the resources (Interrupt Request, Direct Memory Access, etc.) so they
match those used by the host adapter. If the problem still remains, there is probably
a hardware resource conflict between the host adapter and other hardware in your
computer. You can fix this by changing the hardware resource settings. (See your
hardware documentation.)
What do I need to do if I want to use another host adapter?
1 Open the Control Panel, double-click on System, and click the Device Man-
ager tab.
2 Double-click the SCSI Controllers icon, select the name of the old host adapter,
and click Remove.
3 Turn OFF the computer and physically remove the currently installed host
adapter.
4 Install the new host adapter according to the instructions in the hardware docu-
mentation.
5 Turn the computer ON. If the new host adapter supports Plug and Play, Win-
dows will install and configure it automatically. Otherwise, runAdd New Hard-
ware to make sure the new driver is loaded.

IX. ADAPTEC EZ-SCSI
If I am running under Windows95, do I need lines for the Adaptec real mode
ASPI drivers and mscdex in my CONFIG.SYS and AUTOEXEC.BAT files?
Usually, you do not need to use these real mode ASPI drivers, because the new
Windows miniport drivers support most SCSI host adapters and SCSI devices. How-
ever, you need to load the drivers (including mscdex, if you have a CDROM drive)
if any of the following is true:
• You are running in MSDOS mode
• You are using a scanner or another SCSI device with CONFIG.SYS- or
AUTOEXEC.BAT-based drivers, such as HP’s sjiix.sys
• You have an older model SCSI-1 CDROM drive that Windows95 does not
support
• You are using a CD-Recorder drive (however, some newer models of CD-
Recorder drives can use the embedded Windows miniport drivers)
To install the Adaptec EZSCSI DOS drivers, click the Start button and select Re-
start the computer in MS-DOS mode. When the DOS prompt appears, follow the
Quick Start instructions for DOS.
My CDROM drive doesn’t work properly under Windows95.
Some older models of SCSI CDROM drives are not compatible with the embedded
Windows95 CDROM driver. You can add support for the CDROM drive by doing
the following:
1 Click the Start button and select Restart the computer in MS-DOS mode.
2 When the DOS prompt appears, follow the Quick Start instructions for DOS.
3 When you are finished running Adaptec EZSCSI for DOS, find the file named
cdtsd.vxd in the windows\system\iosubsys directory and rename it cdtsd.sav.
My CDROM drive shows up as more than one icon under My Computer.
The mapping between mscdex, which runs in real mode, and the Windows95 CDROM
driver does not match. You can correct this in one of two ways:
• Comment out the line that loads mscdex.exe in the AUTOEXEC.BAT file.
• Change the /Lswitch on the line that loads mscdex.exe in the AUTOEXEC.BAT
file so it assigns the CDROM drive the next highest logical drive letter after
the hard disk drives.

Information for DOS/Windows 3.1x Users
The following information may be useful if you install Adaptec EZSCSI on a com-
puter running DOS, Windows 3.1x, or Windows for Workgroups3.1x.
NOTE: The Windows95/WindowsNT Troubleshooting section on page 6 de-
scribes a few situations when you may need to use the DOS/Windows3.1x driv-
ers and ASPI managers under Windows95 or WindowsNT.
DOS and Windows3.1x Device Drivers
Device drivers are software programs that enable your computer to communicate
with SCSI devices such as hard disk drives, CDROM drives, and scanners. Each
kind of device requires a different device driver. Adaptec EZSCSI includes several
DOS/Windows3.1x device drivers that are copied to your hard disk during installa-
tion. Adaptec EZSCSI adds command lines to your CONFIG.SYS and
AUTOEXEC.BAT files to load these device drivers if it finds these kinds of devices
on your computer.
To learn more about the Adaptec EZSCSI device drivers, including their command
line option information, see the online Adaptec EZSCSI Online Reference, a Win-
dows Help application.
DOS and Windows3.1x ASPI Managers
ASPI (Advanced SCSI Programming Interface) managers are software programs
that enable the SCSI device drivers, your host adapter, and your SCSI devices to
communicate with each other. ASPI managers are written for a specific operating
system, such as DOS, and a specific family of Adaptec host adapters.
Adaptec EZSCSI includes several ASPI managers for DOS/Windows3.1x. When
you install Adaptec EZSCSI on these operating systems, it detects what kind of host
adapter is installed in your computer and automatically configures your system with
the correct ASPI manager. To learn more about these ASPI managers, including
their command line option information, see the Adaptec EZSCSI Online Reference,
a Windows Help application.

IX. ADAPTEC EZ-SCSI
DOS Formatting Utilities
Adaptec EZSCSI includes several DOS-based formatting utilities:
Low-level Formatter (scsifmt)
Use the DOS-based scsifmt utility for low-level formatting of SCSI hard disk drives,
®
removable media, Floptical drives, and magneto-optical drives. You can also use
it to scan a disk device for surface defects before you store data on it.
Run scsifmt from the DOS prompt, not from the Windows MSDOS prompt. Before
you run it, be sure the disk devices you want to format are connected to the host
adapter and that they are powered. Then follow these steps:
1. Change to the directory where scsifmt.exe is located (usually c:\scsi), type
scsifmt at the DOS prompt, and press Enter.
NOTE: If you are formatting a SCSI disk device that supports more than one
LUN (for example, Iomega’s Bernoulli dual multidrive) type scsifmt /L at the
command line.
2. When the first screen appears, read it and press Enter to continue. (Press F1 at
any time to view Help.) Information about your SCSI disk devices appears on
the screen.
3. Use the arrow keys to move the highlight bar to a disk device you want to
format or verify, then press Enter.
4. When the next screen appears, select either Format or Verify (to verify that the
disk is free of surface defects), then press Enter.
WARNING! Back up important data before you format the disk device!
A low-level format erases all data from the disk.
5. If you select Format, confirm that you want to format the disk, then wait while
the disk device is formatted. This may take a long time if the disk is large.
If you select Verify, you can press Esc at any time to stop the verification
process. (This does not damage the disk.) If the utility finds bad blocks on the
disk, it displays information about them. You can reassign the bad block(s) to
prevent data from being stored there.
6. Repeat steps 3, 4, and 5, as needed, to format or verify other disk devices.
When you are finished, press Esc to exit.

ASUS P2B-D/P2B-DS User’s Manual
IX. ADAPTEC EZ-SCSI
Formatter and Partitioner (afdisk)
Use the DOS-based afdisk utility to partition and format SCSI hard disk drives,
Floptical drives, and magneto-optical drives. You can also use afdisk to remove
DOS and non-DOS partitions from a disk drive and to format removable media in
standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format.
NOTE: Use afdisk only if the disk device is not controlled by the host adapter BIOS—
that is, if the host adapter does not have a BIOS or if its BIOS is not enabled. If the disk
device is controlled by the host adapter BIOS, use the DOS fdisk utility to partition and
format the disk device. (See the MSDOS documentation.)
Run afdisk from the DOS prompt only, not from the Windows MSDOS prompt.
Before you run it, be sure the disk devices you want to format and partition are
connected to the host adapter and that they are powered. Then follow these steps:
1. Change to the directory where afdisk.exe is located (usually c:\scsi), type afdisk
at the DOS prompt, and press Enter.
Information about your SCSI disk devices appears on the screen. (The number
that appears after Target is the device’s SCSI ID.)
2. Use the arrow keys to move the highlight bar to the disk device you want to
partition, then press Enter.
-
If the selected disk device is controlled by the host adapter BIOS, you can
view information about it but you cannot partition it with afdisk (Use the DOS
fdisk and format utilities.)
