III. H/W SETUP

NOTES: Overclocking your processor is not recommended. It may result in a slower

speed. Voltage Regulator Output Selection (VID) is not required for Pentium III/II/
Celeron processors because they send VID signals directly to the onboard power
regulator.

2. System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are

available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM) of either 8, 16, 32, 64, 128MB, or 256MB.

The Intel 440ZX AGPset does not support ECC function. ECC memory modules
may be used but the ECC function will not be available.

Memory speed setup is recommended through SDRAM Configuration under “Chipset
Features Setup” in BIOS SETUP.

Install memory in any combination as follows:

General DIMM Notes

• For the system CPU bus to operate at 100MHz, use only PC100-compliant
DIMMs. When this motherboard operates at 100MHz, most system will not

even boot if non-compliant modules are used because of the strict timing issues
involved under this speed. If your DIMMs are not PC100-compliant, set the
CPU bus frequency to 66MHz RAM to ensure system stability.

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

• 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.

cards or other system components. Failure to do so may cause severe damage to
both your motherboard and expansion cards.

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. You may use the Microsoft Diagnostics (MSD.EXE) utility located in the W in­dows directory to see a map of your used and free IRQs. If you use W indows 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.

26 ASUS P2-99 User’s Manual

III. HARDWARE SETUP

To simplify this process, this motherboard has complied 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 of the BIOS setup utility can be used to indicate which IRQs are being
used by Legacy cards. For older Legacy cards that do not work with the BIOS, you
can 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 PCI cards that require an IRQ. To install a PCI card, you need to set
something called the INT (interrupt) assignment. Since all the PCI slots on this
motherboard use an INTA #, be sure that the jumpers on your PCI cards are set 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 SETUP, 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 optional 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 (AGP)

the system is powered on and blinks when it is in sleep or soft-off mode.

18. Keyboard Lock Switch Lead (2-pin KEYLOCK)

This 2-pin connector connects to the case-mounted key switch to allow keyboard
locking. NOTE: When the keyboard is locked, the mouse can still be used.

19. System Warning Speaker Connector (4-pin SPEAKER)

This 4-pin connector connects to the case-mounted speaker.

20. System Message LED Lead (2-pin MSG.LED)

This indicates whether a message has been received from a fax/modem. The
LED will remain lit when there is no signal and blink when there is data re­ceived. This function requires an ACPI OS and driver support.

21. System Management Interrupt Lead (2-pin SMI)

This allows the user to manually place the system into a suspend mode or “Green”
mode where system activity will be instantly decreased to save electricity and
expand the life of certain components when the system is not in use. This 2-pin
connector (see the preceding figure) connects to the case-mounted suspend
switch. If you do not have a switch for the connector, you may use the “Turbo
Switch” since it does not have a function. SMI is activated when it detects a
short to open moment and therefore leaving it shorted will not cause any prob­lems. This may require one or two pushes depending on the position of the switch.

22. ATX Power Switch / Soft-Off Switch Lead (2-pin PWR.SW)

The system power is controlled by a momentary switch connected to this lead.
Pushing the button once will switch the system between ON and SLEEP or ON
and SOFT OFF, depending on your BIOS or OS setting. Pushing the switch
while in the ON mode for more than 4 seconds will turn the system off. The
system power LED shows the status of the system’s power.

23. Reset Switch Lead (2-pin RESET)

This 2-pin connector connects to the case-mounted reset switch for rebooting
your computer without having to turn off your power switch. This is a preferred
method of rebooting to prolong the life of the system’s power supply.

The motherboard supports a 5V programmable Flash ROM chip. Either of these
memory chips can be updated when BIOS upgrades are released. 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 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:

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 the BIOS. If you install other SCSI
controller cards, 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.

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 software, you may have to set this to Disabled to prevent write errors.

PM Timers

This section controls the time-out settings for the Power Management scheme. The
fields included in this section are “HDD Power Down”, which places the hard disk
into its lowest power consumption mode, and the “Suspend Mode” which suspends
the CPU.

The system automatically “wakes up” from any power saving mode when there is
system activity such as when a key is pressed from the keyboard, or when there is
activity detected from the enabled IRQ channels.

HDD Power Down (Disable)

Power Up Control

This section determines the ways the system can be controlled when it is started or
restarted, when modem activity is detected, or when power to the computer is inter­rupted and reapplied. The Soft-Off mode refers to powering of f the system through
a momentary button switch (ATX switch) or through the software as opposed to
disconnecting the AC power by way of a rocker switch or other means.

PWR Button < 4 Secs (Soft Off)

When set to Soft Off, the ATX switch can be used as a normal system power-off
button when pressed for less than 4 seconds. Suspend allows the button to have a
dual function where pressing less than 4 seconds will place the system in sleep
mode. Regardless of the setting, holding the ATX switch for more than 4 seconds
will power off the system.

ASUS P2-99 User’s Manual52

IV. BIOS SETUP

PWR Up On Modem Act (Enabled)

This allows either settings of Enabled or Disabled for powering up the computer (turns the
ATX power supply on) when the modem receives a call while the computer is Soft-off.
NOTE: The computer cannot receive or transmit data until the computer and appli­cations are fully running, thus connection cannot be made on the first try. Turning
an external modem off and then back on while the computer is off causes an initializa­tion string that will also cause the system to power on.

AC PWR Loss Restart (Disabled)

This allows you to set whether you want your system to boot up after the power has
been interrupted. Disabled leaves your system off after reapplying power and En-
abled boots up your system after reapplying power.

Wake On LAN (Disabled)

This allows you to remotely power up your system through your network by send­ing a wake-up frame or signal. W ith this feature, you can remotely upload/download
data to/from systems during off-peak hours. Enabled sets this feature.
IMPORTANT: This feature requires the optional network interface and an ATX power
supply with at least 720mA +5V standby power.

Automatic Power Up (Disabled)

This allows you to have an unattended or automatic power up of your system. You may
configure your system to power up at a certain time of the day by selecting Everyday,
which will allow you to set the time or at a certain time and day by selecting By Date.

PNP and PCI Setup

The “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 reassign-

ing of interrupt settings, select the default setting of No.
Slot 1 / Slot 2 / Slot 3 / 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, 1 1, 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.

......................................................................................................................................

ASUS P2-99 User’s Manual54

IV. BIOS SETUP

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 BIOS to detect whether you have a Symbios SCSI card, if detected
the onboard Symbios BIOS will be enabled, if not then it will be disabled. Disabled
prevents the onboard Symbios BIOS to be enabled so that the external Symbios
SCSI card’ s own BIOS can be used instead. Note: 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)

You can select the search order for your VGA card(s). PCI/AGP will detect PCI
VGA cards before AGP, and AGP/PCI will detect AGP cards before PCI VGA.

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

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

IDE HDD Auto Detection

The “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

IV. BIOS SETUP

Hard Disk Detect

<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.
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 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.

IV. BIOS SETUP

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

DMI Utility

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 EEPROM
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.

VI. SOFTWARE REFERENCE

Starting the ASUS DMI Configuration Utility

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

ASUS CIDB Chassis Intrusion Sensor Module

The optional ASUS CIDB is a module for providing audio alarm and logging when
there is an intrusion into the chassis of a computer system. The module detects a chas­sis intrusion by either light striking its photo sensor or by contact when its switch
connectors are shorted by chassis-mounted momentary toggle switches. An intrusion
memory function allows detection by BIOS and LDCM on the next bootup.

Using the ASUS CIDB

1. You must have an ASUS motherboard with a chassis connector.

2. Connect the CIDB directly to the chassis connector or use the provided extension
cable and mount the CIDB to the chassis using a double-sided foam adhesive tape.

CAUTION! The CIDB component pins and metallic points must not come in

contact with another metallic surface or else shorting will occur!

VII. APPENDIX

ASUS CIDB Module

3. Check the hardware settings:

• JP1 jumper should be enabled to use the photo sensor

• MS1 and MS2 connectors should be connected to momentary toggle switches

mounted on the chassis to use the contact method for triggering alarms.

• SW jumper should be enabled to allow the hardware monitoring compo-

nents to receive signals from the CIDB.

4. T o stop the alarm from sounding, use the LDCM software or place a jumper on
(or short manually) the CLR jumper momentarily.

5. If you have an updated BIOS with intrusion support, booting the computer after
an intrusion will require a password which is configured through BIOS.

ASUS CIDB Additional Considerations

1. All motherboards with CIDB: If there is no power to the motherboard (i.e. re­moving the power cord or turning the power supply’s switch off) the alarm will
not sound but the CIDB will still remember an intrusion event which BIOS and
LDCM will detect on the next bootup.

2. Motherboard with chassis intrusion components: Photo sensor, switch, and
memory will not operate with power removed. Power is required to send a signal
to the motherboard’s intrusion memory and buzzer. When using the CIDB on
these motherboards, all the CIDB functions will be disabled, the motherboard’s
intrusion components must still be used. The CIDB can benefit these mother­boards by providing a chassis switch which will operate even when the power is
removed. Pins [2-3] of the SW jumper can be used for a momentary toggle switch
and the CIDB’ s battery will be used to send an intrusion signal to the motherboard’s
intrusion memory.

The ASUS S370 CPU Card

The optional ASUS S370 CPU card allows Slot 1 motherboards to accept socket 370
processors. The ASUS S370 CPU card gives Slot 1 motherboard owners an inexpen­sive way to upgrade their Pentium II computers using lower costing socket 370 pro­cessors. Since socket 370 processors are based on the Pentium II design, the only
difference is the connector and the amount of internal cache within the processor.

The following picture shows the ASUS S370 CPU card with a plastic retainer at­tached to the edge. The retainer is used to hold the ASUS S370 CPU card in place
using the motherboard’s Slot 1 retention mechanism.

Using the ASUS S370

The general procedure for using the ASUS S370 CPU card:

1. Check the voltage setting for your socket 370 processor using the jumpers on
the card if necessary . For current socket 370 processors, the default setting should
be used. See the reverse side of the ASUS S370 CPU card or the next page for
voltage settings.

2. Install the socket 370 processor . Installation of socket 370 processors is exactly
like socket 7 processors. Lift the brown lever to 90° to install the processor and
lower the brown lever to lock the processor.

3. Insert the ASUS S370 CPU card into Slot 1 on the motherboard. The two fins
on the sides of the ASUS S370 CPU card must catch on the retention mecha­nism so that it locks in place.

4. Connect the socket 370 processor’s fan connector to the motherboard.

5. Make sure that no wires or objects come in contact with the fan.
