III. INSTALLATION  
Installation Steps  
Before using your computer, you must complete the following steps:  
1. Set Jumpers on the Motherboard  
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  
Several hardware settings are made through the use of jumper caps to connect jumper  
pins (JP) on the motherboard. See "Map of the Motherboard" on page 4 for loca-  
tions of jumpers. The jumper settings will be described numerically such as [----],  
[1-2], [2-3] for no connection, connect pins 1&2, and connect pins 2&3 respec-  
tively. A "1" is written besides pin 1 on jumpers with three pins. The jumpers will  
also be shown graphically such as  
to connect pins 1&2 and  
to connect  
for  
pins 2&3. Jumpers with two pins will be shown as  
for Short (On) and  
Open (Off). For manufacturing simplicity, the jumpers may be sharing pins from  
other groups. Use the diagrams 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  
diagramed.  
WARNING: Computer motheboards and components contain very delicate  
Integrated Circuit (IC) chips. To protect the motherboard and other  
components 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. Hold components by the edges and try not to touch the IC chips, leads, or  
circuitry.  
3. Use a grounded wrist strap before handling computer 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.

2. Real Time Clock (RTC) RAM  
The CMOS RAM is powered by the onboard button cell battery. To clear the  
RTC data: (1) Turn off your computer, (2) Short the two pads (Labeled: SHORT  
HERE TO CLEAR CMOS) momentarily with a metallic object (3) Turn on your  
computer, (4) Hold down <Delete> during bootup and enter BIOS setup to re-  
enter user preferences.  
Battery Test Jumper (JP1) (For Service Use Only)  
You can test the battery’s current by removing this jumper and attaching a cur-  
rent meter to the pins. WARNING: You must unplug the power cord to your  
power supply to ensure that there is no power to your motherboard. The  
CMOS RAM containing BIOS setup information may be cleared by this  
action. You should enter BIOS to “Load Setup Defaults” and re-enter any  
user information after removing and reapplying this jumper.

4. CPU External (BUS) Frequency Selection (FS0, FS1, FS2)  
These jumpers tell the clock generator what frequency to send to the CPU. These  
allow the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock  
times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).  
5. CPU to BUS Frequency Ratio (BF0, BF1)  
These jumpers set the frequency ratio between the Internal frequency of the CPU  
and the External frequency (called the BUS Clock) within the CPU. These must  
be set together with the above jumpers CPU External (BUS) Frequency Selection.

2. System Memory  
This motherboard supports four 72-pin SIMMs (Single Inline Memory Modules) of  
4MB, 8MB, 16MB, or 32MB to form a memory size between 8MB to 128MB. The  
DRAM can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Symmet-  
ric) or Enhanced Data Output (EDO). SIMMs must be installed in pairs so that each  
bank contains two of the same size memory modules. Maximum memory size of  
SIMM’s must be 128MB or less.  
IMPORTANT: Memory speed setup is required in BIOS Chipset Setup "Auto  
Configuration."  
Install memory in any or all of the banks in any combination as follows:

III. INSTALLATION  
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. Apply thermal jelly to the CPU top and then  
install the fan onto the CPU.  
WARNING: Without a fan circulating air on the CPU and heat sinks, the  
CPU and/or heat sinks can overheat and cause damage to both the CPU and the  
motherboard. (See "CPU Cooling Fan Connector” at the end of this section.)  
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.  
IMPORTANT: You must set jumpers for "CPU to BUS Frequency Ratio" and  
jumpers for "BUS Frequency Selection" depending on the CPU that you install.

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.  
First read your expansion card documentation on any hardware and  
software settings that may be required to setup your specific card.  
NOTE: PCI Slot 4 has a MediaBus extension 2.0 which allows the installation of a  
PCI card or a MediaBus card (optional multifunctional card) but not both.  
Expansion Card Installation Procedure:  
1. Read the documentation for your expansion 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 pos-  
sible 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 PNPAND  
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 an 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.  
ASUS VX97 User’s Manual  
19  
III. INSTALLATION  
Both ISA and PCI expansion cards may need to use IRQs. System IRQs are avail-  
able 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.  
To simplify this process this motherboard has complied 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 as-  
signed 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 does 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. 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 above. You can select a DMA channel in  
the PCI and PNP configuration section of the BIOS Setup utility.  
IMPORTANT: Choose "Yes" for those IRQ's and DMA's you wish to reserve  
for Legacy (Non-PnP) ISA expansion cards in “IRQ xx Used By ISA” and “DMA  
x Used By ISA” of the PNP and PCI Setup in the BIOS SOFTWARE section,  
otherwise conflicts may occur.

connector (see the figure below) 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. May  
require one or two pushes depending on the position of the switch. Wake-up can  
be controlled by settings in the BIOS but the keyboard will always allow wake-  
up (the SMI lead cannot wake-up the system). If you want to use this connector,

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 the <Delete> key 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 simultaneously pressing the <Ctrl>, <Alt>  
and <Delete> keys, or by pushing 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.

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 by any the BIOS. If you install the  
optional PCI-SC200 SCSI controller card into the motherboard (see section VI for  
instructions). If you install other vendor’s SCSI controller card, please refer to their  
respective documentations on how to install the required SCSI drivers.  
To enter specifications for a hard disk drive, you must select first a “type”. You can  
select “User” and specify the specifications yourself manually, or you can select  
from the provided predefined drive specifications. To select, simply press the <Page  
Up> or <Page Down> key to change the option listed after the drive letter.

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 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 uncom-  
mon. 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 drives during bootup. This will allow you to change your  
hard drives (with the power off) and then power on without having to reconfigure  
your hard drive type. If you use older hard drives which do not support this feature,  
then you must configure the hard drive in the standard method as described above  
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.

Virus Warning (Disabled)  
This field protects the boot sector and partition table of your hard disk against acci-  
dental modifications. Any attempt to write to them will cause the system to halt and  
display a warning message. If this occurs, you can either allow the operation to  
continue or use a bootable virus-free floppy disk to reboot and investigate your  
system. This setting is recommended because conflicts with new operating sys-  
tems. Installation of new operating systems require that you disable this to prevent  
write errors.

External Cache (Enabled)  
These fields allow you to Enable or Disable the CPU’s “Level 2” secondary cache.  
Caching allows better performance.  
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 (New Feature!)  
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 (C,A)  
This field determines where the system looks first for an operating system. Options  
are C,CDROM,A; CDROM,C,A; A,C; C,A The setup default setting is to check first  
the hard disk and then the floppy drive; that is, C, A.  
Swap Floppy Drive (Disabled)  
When enabled, the BIOS swaps floppy drive assignments so that Drive A becomes  
Drive B, and Drive B becomes Drive A under DOS.  
Boot Up Floppy Seek (Disabled)  
When enabled, the BIOS will seek the floppy "A" drive one time.  
Floppy Disk Access Control (R/W)  
This allows protection of files from the computer system to be copied to floppy  
drives by allowing the setting of Read Only to only allow reads from the floppy but  
not writes. The setup default R/W allows both reads and writes.  
Boot Up NumLock Status (On)  
This field enables users to activate the Number Lock function upon system boot.  
Boot Up System Speed (High)  
This has no function and should be left on the setup default.  
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.

Typematic Rate Setting (Disabled)  
When enabled, you can set the two typematic controls listed next. Setup default  
setting is Disabled.  
Typematic Rate (Chars/Sec)  
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) (250ms)  
This field sets the time interval for displaying the first and second characters. Four  
delay rate options are available: 250ms, 500ms, 750ms and 1000ms.  
Security Option (System)  
This field determines when the system prompts for the password. The default set-  
ting is System, where the system prompts for the User Password every time you boot  
up. The other option is Setup, where the system always boots up, and prompts for  
the Supervisor Password only when the Setup utility is called up. You can specify a  
password by using the Supervisor Password or User Password option from the main  
screen as explained later in this section.  
PS/2 Mouse Function Control (Auto)  
The default of Auto allows the system to detect a PS/2 Mouse on bootup. If de-  
tected, IRQ12 will be used for the PS/2 Mouse. IRQ12 will be reserved for expan-  
sion cards if a PS/2 Mouse is not detected. Disabled will reserve IRQ12 for expan-  
sion cards and therefore the PS/2 Mouse will not function.  
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 Enable this option otherwise leave this on the setup default of Disabled.  
......................................................................................................................................  
Video 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 640KB and 1024KB by the amount used for this purpose.

Memory Hole at Address (None)  
This features reserves either 14MB-16MB or 15MB-16MB memory address space to  
ISA expansion cards that specifically require this setting. Memory from 14MB and up  
or 15MB and up will be unavailable to the system because expansion cards can only  
access memory up to 16MB.  
....................................................................................................................................  
Onboard FDC Controller (Enabled)  
When enabled, this field allows you to connect your floppy disk drives to the on-  
board floppy drive connector instead of a separate controller card. If you want to  
use a different controller card to connect the floppy drives, set this field to Disabled.  
Onboard FDC Swap A: B: (No Swap)  
This field reverses the drive letter assignments of your floppy disk drives. Two  
options are available: No Swap and Swap AB. If you want to switch drive letter  
assignments, set this field to Swap AB, and the swap will be controlled in hardware.  
This works separately from the BIOS Features floppy disk swap feature. It is func-  
tionally the same as physically interchanging the connectors of the floppy disk drives.  
Onboard Serial Port 1 (3F8H/IRQ4)  
Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for  
the onboard serial connector.  
Onboard Serial Port 2 (2F8H/IRQ3)  
Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for  
the onboard serial connector.  
Onboard Parallel Port (378H/IRQ7)  
This field sets the address of the onboard parallel port connector. You can select  
either: 3BCH / IRQ 7, 378H / IRQ 7, 278H / IRQ 5, Disabled. If you install an I/O  
card with a parallel port, ensure that there is no conflict in the address assignments.  
The PC can support up to three parallel ports as long as there are no conflicts for  
each port.  
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 data transfer  
rate; ECP+EPP allows normal speed operation in a two-way mode.

ECP DMA Select (3)  
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 Disabled, which leaves the second serial port UART to support the COM2 serial  
port connector. See section III of the baseboard manual for the IrDA-compliant  
infrared module connector.  
Onboard PCI IDE Enable (Both)  
You can select to enable the Primary IDE channel, Secondary IDE channel, Both, or  
Disable both channels (for systems with only SCSI drives).  
IDE 0 Master/Slave Mode, IDE 1 Master/Slave Mode (Auto)  
Each channel (0 and 1) has both a master and a slave making four IDE devices  
possible. Because each IDE device may have a different Mode timing (0, 1, 2, 3, 4),  
it is necessary for these to be independent. The default setting of Auto will allow  
auto-detection to ensure optimal performance.

Power Management Setup  
This “Power Management Setup” option allows you to reduce power consumption.  
This feature turns off the video display and shuts down the hard disk after a period  
of inactivity.  
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.  
Details of Power Management Setup  
Power Management (User Defined)  
This field acts as the master control for the power management modes. Max Saving  
puts the system into power saving mode after a brief period of system inactivity;  
Min Saving is almost the same as Max Saving except that this time the system inac-  
tivity period is longer; Disabled disables the power saving features; User Defined  
allows you to set power saving options according to your preference.  
IMPORTANT: Advanced Power Management (APM) should be installed to  
keep the system time updated when the computer enters suspend mode acti-  
vated by the BIOS Power Management. For DOS environments, you need to  
add DEVICE=C:\DOS\POWER.EXE in you CONFIG.SYS. For Windows 3.x  
and Windows 95, you need to install Windows with the APM feature. Abattery  
and power cord icon labeled "Power" will appear in the "Control Panel."  
Choose "Advanced" in the Power Management Field.  
Video Off Option (Susp, Stby->Off )  
This field determines when to activate the video off feature for monitor power manage-  
ment. The settings are Susp, Stby->Off, Suspend->Off, Always on, and All modes->off.

IV. BIOS SOFTWARE  
Video Off Method (V/H SYNC + Blank)  
This field defines the video off features. Three options are available: V/H SYNC +  
Blank, DPMS, and Blank Only. The first option, which is the default setting, blanks  
the screen and turns off vertical and horizontal scanning; DPMS (Display Power  
Management System) allows the BIOS to control the video display card if it sup-  
ports the DPMS feature; Blank Screen only blanks the screen. Use the latter for  
monitors that do not support the “Green” (no power management) feature. NOTE:  
Screen saver software does not work with this feature. While the monitor is shut off,  
this software cannot display.  
Suspend Switch (Enabled)  
This field enables or disables the SMI connector on the motherboard. This connec-  
tor connects to the lead from the Suspend switch mounted on the system case.  
Doze Speed, Stdby Speed  
These two fields set the CPU speed during each mode. The number indicates what  
the normal CPU speed is divided by.  
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 Doze, Standby and Suspend sys-  
tem inactivation modes.  
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 shuts down any IDE hard disk drives in the system after a pe-  
riod of inactivity. This time period is user-configurable to 1-15 Mins or Disable.  
This feature does not affect SCSI hard drives.  
The Doze Mode, Standby Mode, and Suspend Mode fields set the period of time  
after which each of these modes activate. At Max Saving, these modes activate  
sequentially (in the given order) after one minute; at Min Saving after one hour.  
PM Events  
This section sets the wake-up call of the system. If activity is detected from any  
enabled IRQ channels in the left-hand group, the system wakes up from suspended  
mode. You can enable power management for IRQs 3 ~ 15 individually in the list at  
the right of the screen. The power management feature will work on the enabled  
IRQ channels.  
Take note that a Microsoft serial mouse or compatible will use either COM1 (IRQ4)  
or COM2 (IRQ3), and a PS/2 mouse will use IRQ12. If you know which IRQ your  
mouse is using, you can enable the Wake-up Event for that IRQ here and the system  
will wake up when you move the mouse or click its button.  
.......................................................................................................................................  
Sleep Items (IRQ3-IRQ15)  
You can individually Enable or Disable each IRQ to include in the sleep function.  
IRQ8 (Real Time Alarm) is usually set to Disable so that any software alarm clock  
or event calendar can wake up the system.

[Slot Interrupts] (Auto)  
The first four fields on the screen set how IRQ use is determined for each PCI slot.  
Slot 1 (Right) is nearest the memory sockets. The default setting for each field is  
Auto, which uses auto-routing to determine IRQ use. The other options are manual  
settings of NA, 9, 10, 11, 12, 14, or 15 for each slot.  
PCI Latency Timer (32 PCI Clock)  
"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 ISAcard 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. Available 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, 36K, or 64K. If you are using an ICU to accomplish this task,  
leave ISA MEM Block BASE to its default setting of No/ICU.

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

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 (DMICFG.EXE) must be ran 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.

VI. ASUS PCI SCSI Cards  
Symbios SCSI BIOS and Drivers  
Aside from the system BIOS, the Flash memory chip on the motherboard also con-  
tains the Symbios SCSI BIOS. This Symbios SCSI BIOS works in conjunction with  
the optionalASUS PCI-SC200 controller card to provide Fast SCSI-2 interface when  
using compatible SCSI devices or the ASUS PCI-SC860 SCSI controller cards to  
provide Ultra-Fast SCSI-2 interface when using Ultra-Fast SCSI-2 devices.  
All SCSI devices you install on your system require driver software to function.  
The Symbios SCSI BIOS directly supports SCSI hard disks under the DOS, Win-  
dows and OS/2 environments. It also uses device drivers from the DOS floppy disk  
included in the ASUS PCI-SC200 and ASUS PCI-SC860 controller card packages  
to support hard disks and other SCSI devices working under DOS, Microsoft Win-  
dows, Microsoft Windows NT, Novell NetWare and IBM OS/2. These drivers pro-  
vide higher performance than the direct BIOS support. To use these drivers, you  
must install them into your system and add them to your system configuration files.  
Driver support for SCSI devices used with SCO UNIX is also provided. These  
drivers are included in the second SCO UNIX floppy disk. Windows 95 support is  
also available using the device drivers included within the Windows software. The  
ASUS PCI-SC200 and ASUS PCI-SC860 are Plug and Play adapters that are auto  
detected by BIOS and current operating systems that support Plug and Play features.  
For information about these drivers and their usage, please view the Readme files  
included in the driver packages.  
ASUS PCI-SC200 & PCI-SC860 SCSI Cards  
The ASUS PCI-SC200 or the ASUS PCI-SC860 may be bundled with your mother-  
board or purchased separately. Both cards provide the option of connecting internal  
or external SCSI devices for a total of 7 devices on each SCSI card.

VI. ASUS PCI SCSI Cards  
Setting Up the ASUS PCI-SC200 & PCI-SC860  
There are two jumper settings you may need to make on theASUS PCI-SC200 to set  
it up. One setting assigns the PCI INT interrupt, the other sets the card’s termination.  
The ASUS PCI-SC860 has no jumper settings but you should read the “Terminator  
Requirements.”  
Setting the INT Assignment for the ASUS PCI-SC200  
You must use PCI INT A setting in order to properly assign the ASUS PCI-SC200's  
interrupt. On the ASUS PCI-SC200, you assign the INT by setting jumper JP1 or  
JP2. The default setting for the card already is INT A, so you do not need to change  
the setting to use the ASUS PCI-SC200 with this motherboard.

Terminator Requirements for SCSI Devices  
SCSI devices are connected together in a “chain” by cables. Internal devices con-  
nect to theASUS PCI-SC200 orASUS PCI-SC860 with a fifty-pin flat ribbon cable.  
External devices connect to the external port with a SCSI-2 cable. If there are more  
than one internal or external devices, additional devices are connected with cables  
to form a “daisy chain.” Terminating the devices on the ends of the SCSI Bus “chain”  
is necessary for SCSI devices to work properly. Termination of the devices between  
the ends must be Disabled.

ASUS VX97 User's Manual  
VI. ASUS PCI SCSI Cards  
Terminator Settings for the ASUS PCI-SC860  
Many SCSI devices including the ASUS PCI-SC860 use a set of onboard terminat-  
ing resistors to terminate the devices at the ends automatically. Automatic termina-  
tion requires that the SCSI devices be connected in a straight linear connection or  
“chain.” Connect SCSI devices to one or two of the SCSI connectors in a linear  
“chain” for auto termination of the ASUS PCI-SC860 to be effective. Other forma-  
tions will cause your SCSI devices to not mount properly. You must use the end of  
the ribbon cable when using the internal connector(s) to keep a linear path.  
Additional Note: The Symbios Logic SCSI Configuration Utility is a powerful  
tool. If, while using it, you somehow disable all your controllers or cannot enter  
the configuration utility, pressing “Ctrl-A” after memory count during reboot  
allows you to recover and reconfigure.  
Terminator Settings for the ASUS PCI-SC200  
The ASUS PCI-SC200, on the other hand, has “active” termination that you must  
set using jumper JP5. There are two settings, "terminated" and "not terminated," as  
shown below.  
Decide whether or not you need to terminate the ASUS PCI-SC200 based on its  
position in the SCSI chain. Only the devices at each end of the chain need to be  
terminated. If you have only internal or only external devices connected to the  
ASUS PCI-SC200, then you must terminate the ASUS PCI-SC200. If you have  
both internal and external devices connected, you must not terminate the card. See  
the following example which illustrates this concept.

SCSI ID Numbers for SCSI Devices  
All SCSI devices, including the ASUS PCI-SC200 and ASUS PCI-SC860 interface  
card must have a SCSI identification number that is not in use by any other SCSI  
device. There are eight possible ID numbers, 0 through 7. The ASUS PCI-SC200 and  
ASUS PCI-SC860 cards have fixed SCSI IDs of 7. The SCSI ID serves two purposes:  
It uniquely defines each SCSI device on the bus.  
It determines which device controls the bus when two or more devices try to use  
it at the same time.  
SCSI IDs on one channel do not interfere with the IDs on another channel. This ap-  
plies to two SCSI host adapters that implement different buses as well as dual channels  
on a single host adapter. You can connect up to seven SCSI devices to the interface  
card. You must set a SCSI ID number (ID 0 to ID 6) for each device. SCSI devices  
vary in how they set the ID number. Some use jumpers, others have some kind of  
selector switch. Refer to the manual for any device you install for details on how to set  
its ID number.  
SCSI ID Priority  
The ASUS PCI-SC200 and ASUS PCI-SC860 are 8bit single-channel SCSI cards.  
SCSI ID 7 has the highest priority, and SCSI ID 0 has the lowest priority.
