II. FEATURES
Introduction to ASUS TX97 Series of motherboards
Performance
•
SDRAM Optimized Performance - ASUS TX97 series of motherboards sup-
port the new generation memory - Synchronous Dynamic Random Access
Memory (SDRAM) which increases the data transfer rate from 264MB/s max
using EDO memory to 528MB/s max using SDRAM.
•
Double the IDE Transfer Speed - ASUS TX97 series of motherboards with
Intel 430TX PCIset improves IDE transfer rate using Bus Master UltraDMA/33
IDE which can handle data transfer up to 33MB/s. The best of all is that this
new technology is compatible with existing ATA-2 IDE specs so there is no
need to upgrade current hard drives or cables.
•
Concurrent PCI - Concurrent PCI allows multiple PCI transfers from PCI master
busses to memory to CPU.
•
ACPI Ready - ACPI (Advanced Configuration and Power Interface) is also
implemented on all ASUS 430TX series of motherboards. ACPI provide more
Energy Saving Features for the future operating systems (OS) supporting OS
Direct Power Management (OSPM) functionality. With these features imple-
mented in the OS, PCs can be ready around the clock everyday, yet satisfy all
the energy saving standards. To fully utilize the benefits of ACPI, an ACPI-
supported OS such as in the next release of Windows 95 must be used.
•
PC ’97 Compliant - Both the BIOS and hardware levels of ASUS TX97 series
of motherboards meet PC ’97 compliancy. The new PC 97 requirements for
systems and components are based on the following high-level goals: Support
for Plug and Play compatibility and power management for configuring and
managing all system components, and 32-bit device drivers and installation pro-
cedures for both Windows 95 and Windows NT.
Intelligence: (with optional LM78/75 Hardware Monitor only)
•
Fan Status Monitoring and Alarm - To prevent system overheat and system
damage, the CPU fan and system fans are monitored for RPM and failure. Each
fan can be set for its normal RPM range and alarm thresholds.
•
Temperature Monitoring and Alert - To prevent system overheat and system
damage, there is a heat sensor under the CPU and on the motherboard itself to
monitor CPU and system temperature to make sure the system is operating at a
safe heat level to avoid any failures triggered by extremely high temperature.
ASUS TX97-E User’s Manual

II. FEATURES
•
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 ResourcesAlert - Today’s operating systems such as Windows 95, Win-
dows NT, and OS/2, require much more memory and hard drive space to present
enormous user interfaces and run large applications. The system resource moni-
tor will warn the user before the system resources are used up to prevent pos-
sible application crashes. Suggestions will give the user information on manag-
ing their limited resources more efficiently.
•
•
Virus Write Protection - Normally, viruses can destroy data on storage media
such as hard drivers, floppy diskettes, and MO. Some new-generation viruses
will not only destroy data on storage media, but also clear BIOS data which is
usually unprotected. ASUS TX97 series of motherboards were designed to co-
operate with BIOS, chipset, and flash EPROM to disable write permission when
the system’s initialization stage is completed upon boot-up.
CPU Slow Down - When CPU fans or system fans are malfunctioning, 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 tem-
perature falls below a safe level.
•
•
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 a important feature to implement silent PC systems.
Dual Function Power Button (requires ATX power supply) - The system can
be in one of two states, one is Sleep mode and the other is the Soft-Off mode.
Pushing the power button for less than 4 seconds places the system into Sleep
mode. When the power button is pressed for more than 4 seconds, it enters the
Soft-Off mode.
•
•
Remote Ring On (requiresATX power supply) - This allows a computer to be
turned on remotely through a modem. With this benefit on-hand, any user can
access vital information from their computer from anywhere in the world!
Message LED - Chassis 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.

Installation Steps
Before using your computer, you must complete the following steps:
1. Set Jumpers on the Motherboard
2. Install System Memory Modules
3. Install the Central Processing Unit (CPU)
4. Install Expansion Cards
5. Connect Ribbon Cables, Cabinet Wires, and Power Supply
6. Setup the BIOS Software
1. Jumpers
Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the motherboard. See motherboard layout for locations of jumpers. The
jumper settings will be described numerically, such as [----], [1-2], [2-3] for no con-
nection, connect pins 1&2, and connect pins 2&3 respectively. Pin 1 for our mother-
Pin 1
Pin 1
boards is always on top
the keyboard connector away from yourself. 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 pins 2&3. Jumpers with two pins will be shown as
for Short (On) and for Open (Off). For manufacturing simplicity, the jump-
or on the left
when holding the motherboard with
ers 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 motherboards, baseboards and components, such as SCSI
cards, contain very delicate Integrated Circuit (IC) chips. To protect them against
damage from static electricity, you should follow some precautions whenever you
work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a
metal object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or
connectors, or other components.
4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

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, BF2)
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.
WARNING! Frequencies above 66MHz exceed the specifications for the
onboard Intel Chipset and are not guaranteed to be stable.

2. System Memory (SIMM & DIMM)
This motherboard supports four 72-pin, 32-bit SIMMs (Single Inline Memory Mod-
ules) of 4, 8, 16, 32, or 64MB to form a memory size between 8MB to 256MB. The
SIMMs can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Sym-
metric), or Enhanced Data Out (EDO) (BEDO & Parity are not supported). SIMMs
must be installed in pairs so that each Row (see motherboard layout for row loca-
tions) contains 64-bits of the same size and type of memory chips. One side (with
memory chips) of the SIMM module takes up half a row on the motherboard.
Dual Inline Memory Modules (DIMMs) can be used when the SIMM sockets are
not used. Two sockets are available for 3.3Volt (power level) Unbuffered Synchro-
nous DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB to form
a memory size between 8MB to 256MB. One side (with memory chips) of the
DIMM module takes up one row on the motherboard.
IMPORTANT: Memory speed setup is required through “Auto Configuration” in
BIOS Chipset Setup of the BIOS SOFTWARE. If both 60ns and 70ns memory are
used, set “Auto Configuration” to 70ns. Do not use memory modules with more than
24 chips per module. Modules with more than 24 chips exceed the design specifica-
tions of the memory subsystem and will be unstable.

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.
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 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 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 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.
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.
24
ASUS TX97-E User’s Manual
III. INSTALLATION
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 ISAcards, both legacy and PnP, may also need to use a DMA(Direct Memory
Access) channel. DMA assignments for this motherboard are handled the same way
as the IRQ assignment process described earlier. You can select a DMA channel in
the PCI and PnP configuration section of the BIOS Setup utility.
IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy
ISA cards (under PNPAND PCI SETUP of the BIOS SOFTWARE, choose Yes in IRQ
xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).
ISA Cards and Hardware Monitor
The onboard hardware monitor uses the address 290H-297H so legacy ISA cards
must not use this address or else conflicts will occur.

Managing & Updating your Motherboard’s BIOS
Upon first use of the computer system, you should:
1. Create a bootable system floppy diskette by typing [FORMAT A:/S] from the
DOS prompt without creating “AUTOEXEC.BAT” and “CONFIG.SYS” files.
2. Copy PFLASH.EXE to your new diskette.
3. Run PFLASH.EXE from your new diskette and select option 1 “Save Current
BIOS to File.” Enter the “Current BIOS Revision:” for the file name.
Updating BIOS Procedures (only when necessary)
IMPORTANT: If “unknown” is displayed after Flash Type — , the memory chip
is not programmable or is not supported with the PnP BIOS and therefore cannot be
programmed by the Flash Memory Writer utility.
1. Download an updated ASUS BIOS file from the internet (WWW), FTP, or a
BBS (Bulletin Board Service) and save to the diskette you created above. See
ASUS CONTACT INFORMATION on Page II of the User’s Manual for details.
2. Turn off your computer and open the system cabinet to Enable “Boot Block
Programming” jumper as shown in section III of the User’s Manual.
3. Boot from the floppy diskette you created above.
4. At the “A:\” prompt, type: [PFLASH] and then the <Enter> key.
5. Enter 2 “Update BIOS Main Block From File” from the Main Menu or option 2
“Update BIOS Including Boot Block and ESCD” from the Advanced Features
Menu if prompted by option 2 of the Main Menu.
6. The program displays a second screen prompting you for the name of the BIOS
file. Type in the complete file name and extension of the new BIOS, and then
press the <Enter> key. The utility then updates the BIOS file from disk.
WARNING! If you encounter problems while updating the new BIOS, DO
NOT turn off your system since this might prevent your system from booting up.
Just repeat the process, and if the problem still persists, update the original BIOS
file you saved to disk above. If the Flash Memory Writer utility was not able to
successfully update a complete BIOS file, your system may not be able to boot
up. If this happens, your system will need service.
7. After successfully updating the new BIOS file, exit the Flash Memory Writer
utility and then turn off your system. Set the jumper back to its default setting of
Programming “Disabled or Protected.”
8. Turn on your computer and hold down the <Delete> key to enter BIOS setup.

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

Load Defaults
The Load BIOS Defaults option loads the minimum settings for troubleshooting.
Load Setup Defaults, on the other hand, is for loading optimized defaults for regu-
lar use. Choosing defaults at this level will modify all applicable settings.
A section at the bottom of the preceding screen displays the control keys for this
screen. Take note of these keys and their respective uses.
Standard CMOS Setup
Standard CMOS Setup allows you to record some basic system hardware configu-
ration and set the system clock and error handling. If the motherboard is already
installed in a working system, you will not need to select this option anymore. How-
ever, if the configuration stored in the CMOS memory on the board gets lost or
damaged, or if you change your system hardware configuration, you will need to
respecify the configuration values. The configuration values usually get lost or
corrupted when the power of the onboard CMOS battery weakens.
The preceding screen provides you with a list of options. At the bottom of this screen
are the control keys. Take note of these keys and their respective uses.
User-configurable fields appear in a different color. If you need information on the
selected field, press <F1>. The help menu will then appear to provide you with the

NOTE: You can bypass the date and time prompts by creating anAUTOEXEC.BAT
file. For information on how to create this file, refer to the MS-DOS manual.
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 chan-
nel can support up to two hard disks; the first of which is the “master” and the
second is the “slave”.
Specifications for SCSI hard disks need not to be entered here since they operate
using device drivers and are not supported 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 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 hard disk during bootup. This will allow you to change your
hard disks (with the power off) and then power on without having to reconfigure
your hard disk type. If you use older hard disks that do not support this feature, then
you must configure the hard disk in the standard method as described earlier by the
“User” option.
NOTE: After the IDE hard disk drive information has been entered into BIOS, new
IDE hard disk drives must be partitioned (such as with FDISK) and then formatted
before data can be read from and write on. Primary IDE hard disk drives must have
its partition set to active (also possible with FDISK).
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.
Drive A / Drive B (None)
These fields record the types of floppy disk drives installed in your system. The
available options for drives A and B are: 360KB, 5.25 in.; 1.2MB, 5.25 in.; 720KB,

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 (C,A)
This field determines where the system looks first for an operating system. Options are
C,A; A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; A,C and C only; The setup default
setting is to check first the hard disk and then the floppy disk drive; that is, C, A.
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.
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 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.
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.

SDRAM Speculative Read (Disabled)
If Enabled, the CPU will issue predict commands to access the DRAM, if a miss
occurs, the CPU will cancel this command. Some operating systems under certain
situations have a problem utilizing this feature so it is normally Disabled.
Passive Release (Enabled)
This is a mechanism that allows concurrency of ISA/EISA cycles and CPU-to-PCI
cycles. When this feature is enabled, the TXC will be possible to re-arbitrate PCI
bus and allow the CPU to access PCI even when the PCEB has been granted the bus.
Delayed Transaction (Disabled)
If Enabled, this frees the PCI Bus during CPU accessing of 8-bit ISA cards which
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.

8-bit I/O Recovery Time (1 BUSCLK)
Timing for 8-bit ISA cards
Video BIOS Cacheable (Enabled)
Allows the Video BIOS to be cached to allow faster execution. Leave on default
setting of Enabled for better performance, otherwise Disabled.
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 allows you to reverse the hardware drive letter assignments of your floppy
disk drives. Two 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 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, or 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 Disabled.
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.
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 Ultra DMA Mode (Auto)
This sets the IDE UltraDMA to be active when using UltraDMA-capable IDE de-
vices. The BIOS will automatically adjust or disable this setting for slower IDE
devices so that Auto or high settings will not cause problems for older IDE devices.
Choose Disable if you do not want this feature for all devices.
IDE 0 Master/Slave PIO/DMA Mode, IDE 1 Master/Slave PIO/DMA 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. PIO and DMAtimings can be independently set. The default
setting of Auto will allow autodetection to ensure optimal performance.

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 inter-
rupted and reapplied. The Soft-Off mode refers to powering off 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. No Function disables the ATX switch function when the button is pressed
under 4 seconds. Regardless of the setting, holding the ATX switch for more than 4
seconds will power off the system.
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 off.
NOTE: The computer cannot receive or transmit data until the computer and appli-
cations 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 initializa-
tion string that will also cause the system to power on.

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 (RIGHT) IRQ to Slot 4 (LEFT) 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, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot.
PCI Latency Timer (32 PCI Clock)
The default setting of 32 PCI Clock enables maximum PCI performance.
IRQ xx Used By ISA (No/ICU)
These fields indicate whether or not the displayed IRQ for each field is being used
by a legacy (non-PnP) ISA card. Two options are available: No/ICU and Yes. The
first option, the default value, indicates either that the displayed IRQ is not used or
an ISA Configuration Utility (ICU) is being used to determine if an ISA card is using
that IRQ. If you install a legacy ISA card that requires a unique IRQ, and you are not
using an ICU, you must set the field for that IRQ to Yes. For example: If you install
a legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA to Yes.
......................................................................................................................................
DMA x Used By ISA (No/ICU)
These fields indicate whether or not the displayed DMA channel for each field is
being used by a legacy (non-PnP) ISAcard. 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.
SYMBIOS SCSI BIOS (Auto)
The default uses Auto settings for the onboard SCSI BIOS. If you do not want to use
the onboard SCSI BIOS, choose Disabled.

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

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

IMPORTANT: If your hard disk was already formatted on an older previous system,
incorrect parameters may be detected. You will need to enter the correct parameters
manually or use low-level format if you do not need the data stored on the hard disk.
If the parameters listed differ from the ones used when the disk was formatted, the
disk will not be readable. If the auto-detected parameters do not match the ones that
should be used for your disk, do not accept them. Press <N> to reject the presented
settings and enter the correct ones manually from the Standard CMOS Setup screen.
Save & Exit Setup
Select this option to save into the CMOS memory all modifications you specified
during the current session. To save the configuration changes, highlight the “Save
& Exit Setup” option on the main screen, type “Y”, and then press <Enter>.
Exit Without Saving
Select this option to exit the Setup utility without saving the modifications you specify
during the current session. To exit without saving, highlight the “Exit Without Sav-
ing” option on the main screen and then press <Enter>.

Desktop Management Interface (DMI)
Introducing the ASUS DMI Configuration Utility
This motherboard supports DMI within the BIOS level and provides a DMI 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 used in real mode in order
for the program to run, the base memory must be at least 180K. Memory managers
like HIMEM.SYS (required by windows) must not be installed. You can boot up
from a system diskette without AUTOEXEC.BAT and CONFIG.SYS files, “REM”
HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass your
AUTOEXEC.BAT and CONFIG.SYS files.

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, 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 INTA 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.
60
ASUS TX97-E 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 active
resistors to terminate the devices at the ends automatically. Automatic termination
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 formations 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.

Terminated (Default)
Not Terminated
Terminator Setting (Terminated / Not Terminated)
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.
