II. FEATURES

• Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards or other

Symbios SCSI cards through the onboard SYMBIOS firmware.

Performance Features

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter busses to the memory and processor.

• High-Speed Data T ransfer Interface: This motherboard with its chipset and sup-

port for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to 66.6MB/s.
UltraDMA/66 is backward compatible with both DMA/33 and DMA and with
existing DMA devices and systems so there is no need to upgrade current EIDE/
IDE drives and host systems. (UltraDMA/66 requires a 40-pin 80-conductor cable
to be enabled and/or for UltraDMA Mode 4.)

• SDRAM Optimized Performance: Supports the new generation memory —

Synchronous Dynamic Random Access Memory (SDRAM) — which increases
the data transfer rate to 800MB/s max using PC100-compliant SDRAM.

Intelligent Features

• Fan Status Monitoring and Alarm: To prevent system overheat and system

damage, the CPU and chassis fans are monitored for RPM and failure. Each fan
can be set for its normal RPM range and alarm thresholds.

• T emperature Monitoring and Alert: T o avoid any failures triggered by extremely

high temperature, there is a heat sensor under the CPU to make sure your system
is operating at a safe heat level.

II. FEATURES

Smart Series

II. FEATURES

• Auto Fan Off: The system fans will power off automatically even in sleep mode.
This function reduces both energy consumption and system noise, and is an im­portant feature in implementing silent PC systems.

• Dual Function Power Button (requir es A TX power supply): Pushing the power
button for less than 4 seconds when the system is in the working state places the
system into one of two states: sleep mode or soft-off mode, depending on the
BIOS setting (see Power Management Setup under BIOS SETUP). When the
power button is pressed for more than 4 seconds, the system enters the soft-off
mode regardless of the BIOS setting.

• Keyboard Power Up: Keyboard Power Up can be enabled or disabled to allow
the computer to be powered on by pressing the keyboard’s spacebar.

• Voltage Monitoring and Alert: System voltage levels are monitored to ensure
stable current to critical motherboard components. Voltage specifications are more
critical for future processors, so monitoring is necessary to ensure proper system
configuration and management.

• System Resources Alert: Today’s operating systems, such as Windows 95/98/
NT and OS/2, require much more memory and hard drive space to present enor ­mous user interfaces and run large applications. The system resource monitor
will warn the user before the system resources are used up to prevent possible
application crashes. Suggestions on managing the user’s limited resources more
efficiently are provided.

• CPU Slow Down: When CPU fans or system fans malfunction, the system will
deactivate the CPU Clock line to decrease CPU utilization to the speed upon
detection of system overheat. This will prevent CPU damage from system over­heat. The CPU utilization will restore normal operations when temperature falls
below a safe level.

• Remote Ring On (requires external modem): This feature allows a computer to
be turned on remotely through an external modem. With this benefit on hand, any
user can access vital information from their computer from anywhere in the world!

• Message LED (requires ACPI-supported OS): Turbo LEDs now act as infor­mation providers. Through the way a particular LED illuminates, the user can
determine the stage the computer is in. A simple glimpse provides useful infor­mation to the user.

This section explains how to change your motherboard’s function settings through
the use of switches and/or jumpers.

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 o r

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.

The onboard voltage regulator allows you to select the voltage supplied to the
DRAM, chipset, AGP, and the CPU’s I/O buffer. IMPORTANT! Setting this
function switch to 3.6V or 3.8V may reduce system life. It is strongly recom­mended that you leave your switch on its default setting of 3.5V.

2. System Memory (DIMM)

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 to form a memory
size between 8MB and 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 in Chipset Features Setup under BIOS SETUP.

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

IMPORT ANT! (see Notes below)

• To make using bus speeds ≥95MHz possible, SDRAMs used must be com-

patible with the current Intel PC100 SDRAM specification..

Install memory in any combination as follows:

DIMM Location 168-pin DIMM Total Memory

DIMM1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256MB x1

NOTES

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

• To make using bus speeds ≥95MHz possible, use only PC100-compliant

DIMMs. Most systems will not even boot if non-compliant modules are used
because of the strict timing issues involved with speeds ≥95MHz.

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

• BIOS shows SDRAM memory on bootup screen.

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

3. Central Processing Unit (CPU)

The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible
with ZIF Socket 5 processors. The CPU that came with the motherboard should
have a fan attached to it to prevent overheating. If this is not the case then purchase
a fan before you turn on your system.

WARNING! Without a fan circulating air on the CPU, the CPU can overheat
and cause damage to both the CPU and the motherboard.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree right angle. Insert the CPU with the correct orientation as
shown. Use the notched corner of the CPU with the white dot as your guide. The
white dot should point towards the end the of the lever. Notice that there is a blank
area where one hole is missing from that corner of the square array of pin holes and
a “1” printed on the motherboard next to that corner . Because the CPU has a corner
pin for three of the four corners, the CPU will only fit in the one orientation as
shown. The picture is for reference only; you should have a CPU fan that will cover
the face of the CPU. With the added weight of the CPU fan, no force is required to
insert the CPU. Once completely inserted, hold down on the fan and close the
socket’s lever.

4. Expansion Cards

WARNING! Make sure that you 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 your expansion card documentation on any hardware and software set­tings that may be required to setup your specific card.

2. Set any necessary jumpers on your expansion card.

3. Remove your computer system’s cover.

4. Remove the bracket on the slot you intend to use.
Keep the bracket for possible future use.

5. Carefully align the card’s connectors and press firmly.

6. Secure the card on the slot with the screw you removed in step 4.

7. Replace the computer system’s cover.

8. Setup the BIOS if necessary
(such as “IRQ xx Used By ISA: Yes” in PNP AND PCI SETUP)

9. 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 by parts of the system which leaves 6 free for
expansion cards.

Both ISA and PCI expansion cards may need to use IRQs. System IRQs are avail­able to cards installed in the ISA expansion bus first, and any remaining IRQs are
then used by 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 Microsoft’s Diagnostic (MSD.EXE)
utility included in the Windows directory to see a map of your used and free IRQs.
For Windows 95 users, the “Control Panel” icon in “My Computer,” contains a
“System” icon, which gives you a “Device Manager” tab. Double clicking on a
specific device give you “Resources” tab which shows the Interrupt number and
address. Make sure that no two devices use the same IRQs or your computer will
experience problems when those two devices are in use at the same time.

III. H/W SETUP

Expansion Cards

ASUS P5S-B User’s Manual 29

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 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 a PCI slot that has a card in it that requires an IRQ. T o install a PCI card, you need
to set something called the INT (interrupt) assignment. Since all the PCI slots on this

Expansion Cards

III. H/W SETUP

motherboard use an INT A #, be sure that the jumpers on your PCI cards are set to INT A.

Assigning DMA Channels for ISA Cards

III. HARDWARE SETUP

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 (in PNP AND P C I SETUP under 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 onboard hardware monitor uses the address 290H-297H, so legacy ISA cards
must not use this address or else conflicts will occur.

5. External Connectors

WARNING! Some pins are used for connectors or power sources. These are
clearly separated from jumpers in the motherboard layout. Placing jumper caps
over these will cause damage to your motherboard.

IMPORTANT! Ribbon cables should always be connected with the red stripe on the
Pin 1 side of the connector. The four corners of the connectors are labeled on the
motherboard. Pin 1 is the side closest to the power connector on hard drives and some
floppy drives. IDE ribbon cable must be less than 18in. (46cm), with the second drive
connector no more than 6in. (15cm) from the first connector.

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.

Hard Disk Drives

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, Large, LBA , or Auto (see be-
low). 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 sup-
port 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.

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.

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; CDROM A,C; D,A; E,A; F,A; C only; LS/ZIP,C;
LAN,A,C; LAN,C,A; and C,A. The setup default setting, A,C, checks first the floppy
disk and then the hard disk drive.

Boot Up Floppy Seek (Disabled)

When enabled, the BIOS will seek drive A one time.

Floppy Disk Access Control (R/W)

This allows protection of files from the computer system to be copied to floppy disk
drives 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.

HDD S.M.A.R.T. capability (Disabled)

This field enables or disables S.M.A.R.T. (Self-Monitoring Analysis and Reporting
Technology) support for S.M.A.R.T.-capable hard disk drives. This technology re­quires an application that can display S.M.A.R.T. warning messages.

PS/2 Mouse Function Control (Auto)

The setting of Auto allows the system to detect a PS/2 Mouse on bootup. If detected,
IRQ12 will be used for the PS/2 Mouse. If not detected, IRQ12 will be reserved for
expansion cards. Enabled will reserve IRQ12 for the PS/2 Mouse.

OS/2 Onboard Memory > 64M (Disabled)

When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to Enable this option otherwise leave this on the setup default of Disabled.

PCI/VGA Palette Snoop (Disabled)

Some display cards that are nonstandard VGA, such as graphic accelerators or MPEG
video cards may not show colors properly. Setting this to Enabled should correct
this problem. Otherwise, leave this on the default setting of Disabled.

ASUS P5S-B User’s Manual52

IV. BIOS SETUP

Video ROM BIOS Shadow (Enabled)

This field allows you to change the video BIOS location from ROM to RAM. Relocat­ing to RAM enhances system performance, as information access is faster than the ROM.

C8000 - CBFFF Shadow to DC000 - DFFFF Shadow (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 640KB and 1024KB 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 Typematic Rate and Delay.

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.

Typematic Delay (Msec) (250)

This field sets the time interval for displaying the first and second characters. Four
delay rate options are available: 250, 500, 750, and 1000.

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.

Memory Hole At Address (None)

This allows you to specify the memory address space to be reserved for ISA expan­sion cards that specifically require this setting. Setting the address space to a par­ticular setting (available settings: 15M-16M, 14M-16M, 12M-16M) will make that
memory space unavailable to the system. Expansion cards can only access memory
up to 16M. The default is None.

Delayed Transaction (Enabled)

If Enabled, this frees the PCI Bus during CPU accessing of 8-bit ISA cards that
normally consume about 50-60 PCI Clocks without PCI delayed transaction. If PCI
Bus Masters cannot use the PCI Bus, leave this on the default setting of Disabled for
some ISA cards that are not PCI 2.1 compliant.

VGA Shared Memory Size (4MB)

This allows you to specify the memory size (available settings: 2MB, 4MB, 8MB) to
be shared with the onboard VGA controller. Default setting is 4MB.

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

Onboard FDC Controller (Enabled)

When enabled, this field allows you to connect your floppy disk drives to the onboard
floppy drive connector instead of a separate controller card. If you want to use a differ­ent controller card to connect the floppy disk drives, set this field to Disabled.

Onboard FDC Swap A & B (No Swap)

This field allows you to reverse the hardware drive letter assignments of your floppy
disk drives. T wo options are available: Swap AB and No Swap (default). If you want
to switch drive letter assignments, set this field to Swap AB, and the swap will be
controlled by the onboard chipset.

Onboard Serial Port 1 (3F8H/IRQ4)

Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for

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.

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 Function (Disabled)

This motherboard supports Universal Serial Bus (USB) devices. Set to Enabled if
you want to use USB devices. Your system must support USB function. The default
setting is Disabled.

USB IRQ (Auto)

This field allows you to reserve an IRQ# (3, 4, 5, 7, 9, 10, 11, 12, 14, or 15) for the
USB to work. Auto assigns an IRQ# automatically to your USB device. If you are
not using a USB device, you may disable this feature by setting it to NA to save an

fer data to and from the disk drive. PIO Mode 4, which is the mode installed, differs only
from the standard PIO transfer in how often the drive issues interrupts. In PIO Mode 4, each
interrupt indicates the drive is ready for 4 sectors of data (read) or has completed the trans­fer of 4 sectors of data (write), compared with the one interrupt required in standard PIO for
each sector. This eliminates some of the system overhead involved in a PIO transfer.

equipped systems. This mode is capable of very fast transfer rates using Bus Mastering.
The advantage of using the Bus Master DMA is that it uses less CPU resources than PIO
and therefore, it is useful in multitasking environments, where the CPU can work on a
different program while data is transferred to or from IDE devices, such as hard disk or
CD-ROM drives. Ultra DMA, which is the mode installed, is also known as Ultra-ATA
(AT A is the “official” name for what the computer industry calls IDE or Integrated Drive
Electronics) or Ultra-DMA/33. It is the latest advancement to the ATA specifications.
Ultra-DMA, among others, almost doubles the maximum transfer speed of the ATA-3

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 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.

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
