Installation Steps

Before using your computer, you must complete the following steps:

1. Set Jumpers

2. Install 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

WARNING! Computer motherboards and expansion 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.

Jumpers

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. Keyboard Power Up (KBPWR)

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 300mA on the +5VSB lead and the new ACPI BIOS support. The default is
set to Disable because not all computers have the appropriate ATX power sup­ply. Your computer will not function if you set this to Enable and if you do not
have the right ATX power supply.

2. AGP Frequency Selection (AGPFS)

This option sets the frequency ratio between the AGP bus frequency and the

CPU bus frequency. The default sets the AGP frequency to 2/3 of the CPU bus
or host frequency.

IMPORTANT: Due to limitations in the VIA Apollo Pro Plus chipset, the AGP
frequency should only be set to twice that of the PCI frequency (AGP Frequency=2
x PCI Frequency). Thus AGP frequency must be set in conjunction with the CPU
bus frequency to avoid this limitation. (See next page for frequency settings.)

III. INSTALLATION

4. CPU Bus Frequency (FS0, FS1, FS2, FS3)

This option tells the clock generator what frequency to send to the CPU, DRAM, and
chipset. 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 frequency (the ad­vertised CPU speed).

5. 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 to 768MB. 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:

DIMM Location 168-pin DIMM Total Memory

Socket 1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256MB x1
Socket 3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256MB x1

Total System Memory (Max 768MB) =

NOTES

• At the time this User ’s Manual was written, 256MB DIMMs are only available as
registered memory.

• DIMMs that have more than 18 chips are not supported on this motherboard.

• For the system CPU bus to operate 100MHz, use only PC100-compliant DIMMs.
When this motherboard operates at 100MHz, most system will not even boot if non­compliant modules are used because of the strict timing issues involved under these

speeds. If your DIMMs are not PC100-compliant, set the CPU bus frequency to
66MHz for system stability.

• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.

• SDRAM chips are generally thinner with higher pin density than EDO (Extended
Data Output) chips.

• BIOS shows SDRAM memory on bootup screen.

• Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64, 128,
256MB.

intend to use. Keep the bracket for possible future use.

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 PCI audio onboard, an extra IRQ will be used, leaving 5 IRQs
free. If your motherboard has ISA 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 avail­able to cards installed in the ISA expansion bus first, then any remaining IRQs are
available to PCI cards. Currently , there are two types of ISA cards. The original ISA
expansion card design, now referred to as legacy ISA cards, requires that you con­figure the card’ s jumpers manually and then install it in any available slot on the ISA
bus. If you use W indows 98, selecting the Interrupt request (IRQ) button in Prop-
erties under Device Manager displays the resource settings being used by a par-
ticular device. In Windows 95, the Resources tab under Device Manager displays
these settings. (T o gain access to Device Manager in either W indows 98/95, double­click 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 P2V 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 when­ever 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. T o install a PCI card, you
need to set the INT (interrupt assignment). Since all the PCI slots on this mother­board use an INTA #, set the jumpers on your PCI cards to INT A.

Assigning DMA Channels for ISA Cards

Some ISA cards, 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 PNP AND 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.

6. BIOS Setup

The motherboard supports 5-Volt programmable Flash ROM chip. This memory
chip can be updated when BIOS upgrades are released. Use the Flash Memory W riter
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 sys­tem 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 com­puter, the system provides you with the opportunity to run this program. This ap­pears 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:

This “Standard CMOS Setup” option allows you to record some basic system hard­ware 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.

NOTE: You can bypass the date and time prompts by creating an AUTOEXEC.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 chan­nel 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 by any the BIOS. If you install either the
optional PCI-SC200 or PCI-SC860 SCSI controller card into the motherboard, see
section VI for instructions. If you install other vendor’s SCSI controller card, refer
to their respective documentations on how to install the required 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 auto­matically 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, Lar ge, 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).

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. Be­cause 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.

This “PNP and PCI Setup” option configures the PCI bus slots. All PCI bus slots on
the system use INTA#, thus all installed PCI cards must be set to this value.

NOTE: SETUP Defaults are noted in parenthesis next to each function heading.

Details of PNP and PCI Setup

PNP OS Installed (No)

This field allows you to use a Plug-and-Play (PnP) operating system to configure
the PCI bus slots instead of using the BIOS. Thus interrupts may be reassigned by

the OS when Yes is selected. When a non-PnP OS is installed or to prevent reassign­ing of interrupt settings, select the default setting of No.

Slot 1 IRQ to Slot 4 IRQ (Auto)
These fields set how IRQ use is determined for each PCI slot. The default setting for
each field is Auto, which uses auto-routing to determine IRQ use. The other options are
manual settings of NA, 3, 4, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot.

PCI Latency Timer (32 PCI Clock)

The default setting of 32 PCI Clock enables maximum PCI performance for this
motherboard.

IRQ xx Used By ISA (No/ICU)

These fields indicate whether or not the displayed IRQ for each field is being used
by a legacy (non-PnP) ISA card. Two options are available: No/ICU and Yes. The
first option, the default value, indicates either that the displayed IRQ is not used or
an ISA Configuration Utility (ICU) is being used to determine if an ISA card is
using that IRQ. If you install a legacy ISA card that requires a unique IRQ, and you
are not using an ICU, you must set the field for that IRQ to Yes. For example: If you
install a legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA to Yes.

DMA x Used By ISA (No/ICU)

These fields indicate whether or not the displayed DMA channel for each field is
being used by a legacy (non-PnP) ISA card. A vailable options include: No/ICU and
Yes. The first option, the default setting, indicates either that the displayed DMA
channel is not used or an ICU is being used to determine if an ISA card is using that
channel. If you install a legacy ISA card that requires a unique DMA channel, and
you are not using an ICU, you must set the field for that channel to Yes.

ISA MEM Block BASE (No/ICU)

This field allows you to set the base address and block size of a legacy ISA card that
uses any memory segment within the C800H and DFFFH address range. If you
have such a card, and you are not using an ICU to specify its address range, select a
base address from the six available options; the ISA MEM Block SIZE field will
then appear for selecting the block size. If you have more than one legacy ISA card
in your system that requires to use this address range, you can increase the block
size to either 8K, 16K, 32K, or 64K. If you are using an ICU to accomplish this task,
leave ISA MEM Block BASE to its default setting of No/ICU.

SYMBIOS SCSI BIOS (Auto)

Auto allows the motherboard’s BIOS to detect whether you have a Symbios SCSI
card. If a Symbios SCSI card is detected, the motherboard’ s Symbios BIOS will be
enabled; if no Symbios SCSI card is detected, the onboard Symbios SCSI BIOS will
be disabled. Disabled will disable the motherboard’s Symbios SCSI BIOS so that
the BIOS on an external Symbios SCSI card can be used. (If your Symbios SCSI
card does not have a BIOS, the Symbios SCSI card will not function.)

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.

VGA BIOS Sequence (PCI/AGP)

If your computer has both PCI and AGP VGA cards, this field allows you to select
which of the cards will act as your primary card. The default, PCI/AGP, allows your
PCI card to take precedent when detected. AGP/PCI uses the AGP card as your
primary card.

Supervisor Password and User Password

These two options set the system passwords. “Supervisor Password” sets a pass­word 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>. A password 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 re­verts 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.

Forgot the password?

If you forgot the password, you can clear the password by erasing the CMOS Real
Time Clock (RTC) RAM. The RAM data containing the password information is
powered by the onboard button cell battery. To erase the RTC RAM: (1) Unplug
your computer, (2) Short the solder points, (3) Turn ON your computer, (4) Hold
down <Delete> during bootup and enter BIOS setup to re-enter user preferences.

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 dis­played 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 En­hanced IDE support for four devices, you can only install two IDE hard disk drives.
Y our 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 con­troller 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.

ASUS P2V User’s Manual54

IV. BIOS SOFTWARE

IMPORTANT: If your hard disk was already formatted on an older previous system,
incorrect parameters may be detected. You will need to enter the correct parameters
manually or use low-level format if you do not need the data stored on the hard disk.

If the parameters listed differ from the ones used when the disk was formatted, the
disk will not be readable. If the auto-detected parameters do not match the ones that
should be used for your disk, do not accept them. Press <N> to reject the presented
settings and enter the correct ones manually from the Standard CMOS Setup screen.

Save & Exit Setup

Select this option to save into the CMOS memory all modifications you specified
during the current session. To save the configuration changes, highlight the “Save
& Exit Setup” option on the main screen, type “Y”, and then press <Enter>.

Exit Without Saving

Select this option to exit the Setup utility without saving the modifications you specify
during the current session. To exit without saving, highlight the “Exit W ithout Sav­ing” option on the main screen and then press <Enter>.

Desktop Management Interface (DMI)

Introducing the ASUS DMI Configuration Utility

This motherboard supports DMI within the BIOS level and provides a DMI Con­figuration 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 Con­figuration Utility also allows the system integrator or end user to add additional
information into the MIFD such as serial numbers, housing configurations, and ven­dor 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 updat­ing 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.
