Introduction to ASUS TX97 Series of Motherboards
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 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 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.

FEATURES .II Series) (TX97
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 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.

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 connection, connect pins 1&2, and connect pins 2&3 respectively. Pin 1 for our moth-

with three pins. The jumpers will also be shown graphically such as |

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- |
||||
|
||||||
|
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.

Jumper Settings
1.Real Time Clock (RTC) RAM (RTCLR)
The CMOS RAM is powered by the onboard button cell battery. To clear the RTC data: (1) Turn off your computer and remove the AC power , (2) Move this jumper to “Clear Data,” (3) Move the jumper back to “Operation,” (4) Turn on your computer, (5) Hold down <Delete> during bootup and enter BIOS setup to re-enter user preferences.
Battery Test Jumper (RTCLR)
You can test the battery’s current by removing this jumper and attaching a current meter to pins 1&2. 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.

DIMM Memory Installation Procedures:
Insert the module(s) as shown. Because the number of pins are different on either side of the breaks, the module will only fit in the orientation as shown. DRAM SIMM modules have the same pin contact on both sides. SDRAM DIMM modules have different pint contact on each side and therefore have a higher pin density.

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 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.

III.INSTALLATION
4.Expansion Cards
WARNING! Make sure that you unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.
Expansion Card Installation Procedure:
1.Read your expansion card documentation on any hardware and software settings that may be required to setup your specific card.
2.Set any necessary jumpers on your expansion card.
3.Remove your computer system’s cover.
4.Remove the bracket on the slot you intend to use. Keep the bracket for possible future use.
5.Carefully align the card’s connectors and press firmly.
6.Secure the card on the slot with the screw you removed in step 4.
7.Replace the computer system’s cover.
8.Edit the BIOS settings 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 gives you the “Resources” tab, which shows the Interrupt number and address. Make sure that no two devices use the same IRQs or your computer will experience problems when those two devices are in use at the same time.

III. 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.
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 earlier. You can select a DMA channel in the PCI and PnP configuration section of the BIOS Setup utility.
IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy ISA cards (under PNP AND PCI SETUP of the BIOS 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.
