Introduction to ASUS TX97 Series of motherboards
II. FEATURES
(TX97 Series)
Performance:
• SDRAM Optimized Performance - ASUS TX97 series of motherboards support 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.
• 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 implemented 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 ACPIsupported 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 procedures for both Windows 95 and Windows NT.
Intelligence:
• 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.

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, Windows NT, and OS/2, require much more memory and hard drive space to present
enormous 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 will give the user information on managing 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 cooperate 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 temperature 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 (requires ATX 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.

III. INSTALLATION
(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 locations 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 respecor on the left
when
tively. Pin 1 for our motherboards is always on top
holding the motherboard with 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 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.

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.)
III. INSTALLATION
(CPU)
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.
Expansion Card Installation Procedure:
III. INSTALLATION
(Expansion Cards)
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 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 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.
24
ASUS TX97-X User’s Manual
III. INSTALLATION
To simplify this process this motherboard has complied with the Plug and Play (PNP)
specification which was developed to allow automatic system configuration whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available.
If the system has both Legacy and PNP ISA cards installed, IRQs are
assigned to PNP cards from those not used by Legacy cards. The PCI and PNP
configuration of the BIOS setup utility can be used to indicate which IRQs are being
used by Legacy cards. For older Legacy cards that does not work with the BIOS,
you can contact your vendor for an ISA Configuration Utility.
III. INSTALLATION
(DMA
(Connectors)
Channels)
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.

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 the
optional ASUS 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

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 below). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set
it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to
allow larger IDE hard disks; set it to Large for drives over 528MB that do not support LBA. Large type of drive can only be used with MS-DOS and is very uncommon. Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootup
For each field: Primary Master, Primary Slave, Secondary Master, and Secondary
Slave, you can select Auto under the TYPE and MODE fields. This will enable auto
detection of your IDE 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).

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 which logical drive (not partitions) the system looks first for
an operating system. Options are A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; C
only, A,C. The setup default setting is to check first the hard disk and then the floppy

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

DMA x Used By ISA (No/ICU)
These fields indicate whether or not the displayed DMA channel for each field is
being used by a Legacy (non-PnP) ISA card. 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 C800, CC00, D000, D400, D800, and DC00
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.

drive, press the <N> key. 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 the <N> key to skip rather than to accept a set of parameters causes
the program to enter zeros after that drive letter.
Remember that if you are using another IDE controller that does not feature Enhanced IDE support for four devices, you can only install two IDE hard disk drives.
Your IDE controller must support the Enhanced IDE features in order to use Drive E
and Drive F. The onboard PCI IDE controller supports Enhanced IDE, with two
connectors for connecting up to four IDE devices. If you want to use another controller that supports four drives, you must disable the onboard IDE controller in the
Chipset Features Setup screen.
When auto-detection is completed, the program automatically enters all entries you
accepted on the field for that drive in the Standard CMOS Setup screen. Skipped
entries are ignored and are not entered in the screen.
If you are auto-detecting a hard disk that supports the LBA mode, three lines will
appear in the parameter box. Choose the line that lists LBA for an LBA drive. Do
not select Large or Normal.
The auto-detection feature can only detect one set of parameters for a particular IDE
hard drive. Some IDE drives can use more than one set. This is not a problem if the
drive is new and there is nothing on it.

Desktop Management Interface (DMI)
Introducing the ASUS DMI Configuration Utility
This motherboard supports DMI within the BIOS level and provides a DMI Configuration Utility to maintain the Management Information Format Database (MIFD).
DMI is able to auto-detect and record information pertinent to a computer’s system
such as the CPU type, CPU speed, and internal/external frequencies, and memory
size. The onboard BIOS will detect as many system information as possible and
store those collected information in a 4KB block in the motherboard’s Flash EPROM
and allow the DMI to retrieve data from this database. Unlike other BIOS software,
the BIOS on this motherboard uses the same technology implemented for Plug and
Play to allow dynamic real-time updating of DMI information versus creating a new
BIOS image file and requiring the user to update the whole BIOS. This DMI Configuration Utility also allows the system integrator or end user to add additional
information into the MIFD such as serial numbers, housing configurations, and vendor information. Those information not detected by the motherboard BIOS and has
to be manually entered through the DMI Configuration Utility and updated into the
MIFD. This DMI Configuration Utility provides the same reliability as PnP updating and will prevent the refreshing failures associated with updating the entire BIOS.

VI. ASUS PCI-SC200
(SCSI BIOS)
SCSI BIOS and Drivers
Aside from the system BIOS, the Flash memory chip on the motherboard also contains the SCSI BIOS. This SCSI BIOS works in conjunction with the optional ASUS
PCI-SC200 SCSI controller card to provide a complete PCI Fast SCSI-2 interface.
All SCSI devices you install to your system require driver software to function. The
SCSI BIOS directly supports SCSI hard disks under the DOS, Windows and OS/2
environments. It also uses device drivers from the DOS floppy disk included in the
PCI-SC200 controller card package to support hard disks and other SCSI devices
working under DOS, Windows, Windows NT, Novell NetWare and OS/2. These
drivers provide 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 is a Plug and Play adapter that is auto detected by
BIOS and current operating systems that support Plug and Play features.
For information about these drivers and their usage, see the Readme files included
in the driver packages. You can print out the contents of these files using any text
editor program.
The next few pages will instruct you on the installation of the ASUS PCI-SC200
Fast SCSI Card.

(Setup)
The ASUS PCI-SC200 SCSI Interface Card
Your motherboard may have come with an optional SCSI (Small Computer System
Interface) controller card, the PCI-SC200. The card is also available separately. This
card works with the SCSI BIOS on the motherboard. Together, they provide a complete PCI Fast SCSI-2 interface. With the card installed in your system you can
connect SCSI devices installed in your system case to the internal connector on the
card. You also have the additional option of connecting external SCSI devices to the
external SCSI-2 connector on the card.
If you get the ASUS PCI-SC200 later on as an option, you will need to install it
yourself. The setup procedure is explained here.
Setting Up the ASUS PCI-SC200
There are two jumper settings you may need to make on the card to set it up. One
setting assigns the PCI INT interrupt, the other sets the card’s termination.

ASUS TX97-X User's Manual
VI. ASUS PCI-SC200 SCSI Card

(Jumpers)
Setting the INT Assignment
You must use PCI INT A setting in order to properly assign the card'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 Settings
SCSI devices are connected together in a “chain” by cables. Internal devices connect to the ASUS PCI-SC200 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.” The SCSI chain must be “terminated” at both ends, or the devices in the
chain will not work properly.
Many SCSI devices use a set of terminating resistors to terminate the device. The
ASUS PCI-SC200 has “active” termination that you set using jumper JP5. If you
need to terminate the ASUS PCI-SC200, you do it by setting the jumper. The are two
settings, "terminated" and "not terminated," as shown below.

(SCSI ID Numbers)
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
All SCSI devices, including the ASUS PCI-SC200 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 has a fixed SCSI ID of 7.
You can connect up to seven SCSI devices to the interface card. You must set a SCSI
ID number 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.
