Introduction
The PCI 430 TX system board is a high-performance personal computer
system board based on a 3.3v version of the PentiumTM micrprocessor--the
P54C and P55C, K6 and M2 with MMX microprocessor . The system board
supports the Peripheral Component Interconnect (PCI) Local Bus Standard
and provide four 32-bit PCI bus master slots.
A cache subsystem can be configured for 256k or 512K cache memory to
improve overall throughput.
The system board uses the highly integrated Intel 82439TX chipset to
support the PCI/ISA and green standards, and to provide the Host/PCI
bridge. The 82437AB chipset also support the ACPI soft power off and
Modem Ring wake-up function, it also integrates all system control functions.

Hardware Installation
2.1 Central Processing Unit: CPU
The 430 TX motherboard operates with Intel® P54C/P55C, Cyrix® 6x86/
M2 and AMD ® 5K86/K6 processors. It could operates with 2.8V to 3.52V
processors. The motherboard provides a 321-pin ZIF Socket 7 for easy CPU
installation, a DIP switch (SW1) to set the proper speed for the CPU and a
Jumper block (JV3 - JV7) for setting the CPU voltage. The CPU should
always have a cooling fan attached to prevent overheating.
2-1
1. Pull the lever sideways away
from the socket then raise
the lever up to a 90-degree
angle.
3. Press the lever down to
complete the installation.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU, match
Pin 1 with the white dot/cut
edge then insert the CPU. It
should insert easily.
2.1-1 CPU Installation Procedure

CHAPTER 2 HARDWARE INSTALLATION
1. The 3 CPU clock frequencies that the system supports are 55MHz, 60MHz,
66MHz and 75MHz (To adjust SW1 pin 4, 5, and 6 ). See the following
chart to set the different Host Clock Frequencies.
4 5 6 Clock
ON ON OFF 55MHz
ON OFF OFF 60MHz
OFF OFF OFF 66MHz
OFF ON OFF 75MHz
SW1
CPU
2 . The DIP Switch SW1 (1,2, and 3) is used to set the Core/Bus (Fraction)
ratio of the CPU. The actual core speed of the CPU is the Host Clock
Frequency multiplied by the Core/Bus ratio. For example:
If CPU Clock = 66MHz
Core/Bus ratio = 3 / 2
then CPU core speed = Host Clock x Core/Bus ratio
= 66MHz x 3/2
= 100MHz
3. The PCI Bus Clock is the CPU Clock Frequency divided by 2.

2.5-2 Memory Installation Procedures:
1. The SIMM slot has a “Plastic Safety
Tab” and the SIMM memory module
has a “Notched End”, so the SIMM
memory module can only fit in one
direction.
2. Insert the SIMM memory modules into
the socket at 45-degree angle, then
push into a vertical position so that it
will snap into place.
3. The Mounting Holes and Metal Clips
should fit over the edge and hold the
SIMM memory modules in place.

1. Make sure that the SIMM banks are using the same type and equal size
density memory.
2 . To operate properly at least two 72-pin SIMM module must be installed in
the same bank or one 168-pin DIMM module must be installed.
3. Look at the table below:
4 . Before using SIMM and DIMM modules, look at the chart next page.
5 . Each RAS can not exceed 16 pcs of DRAM.
6. It is not recommended to mix 3V SDRAM with 5V EDO/FP , for it may
cause unreliability.
6 . If SDRAM and EDO/FPM are mixed in a system, then the configuration is
limited to a miximum of four RAS(two RAS of x4 EDO/FPM and two RAS
of x8 or x16 SDRAM). If only x8 or x16 EDO/FPM and SDRAM devices
are used(i.e. not x4’ s), then five RAS can be supported.
7 . If you use a 64M DRAM of SDRAM, then Bank0 can not be use.

Security Option
This category allows you to limit access to the system and Setup, or
just to Setup.
System The system will not boot and access to Setup
will be denied if the correct password is not
entered at the prompt.
Setup(default) The system will boot, but access to Setup will
be denied if the correct password is not entered
at the prompt.
Note: T o disable security , select P ASSWORD SETTING at Main Menu and
then you will be asked to enter password. Do not type anything and
just press <Enter>, it will disable security. Once the security is
disabled, the system will boot and you can enter Setup freely.
PCI VGA Palette Snooping
Choose Disabled or Enabled. Some graphic controllers which are not
VGA compatible, take the output from a VGA controller and map it to their
display as a way to provide the boot information and the VGA compatibility .
However, the color information coming from the VGA controller is
drawn from the palette table inside the VGA controller to generate the proper
colors, and the graphic controller needs to know what is in the palette of the
VGA controller . T o do this, the non-VGA graphic controller watches for the
Write access to the VGA palette and registers the snoop data. In PCI based
systems, where the VGA controller is on the PCI bus and a non-VGA graphic
controller is on an ISA bus, the W rite Access to the palette will not show up
on the ISA bus if the PCI VGA controller responds to the W rites.
3-13
Page 47
CHAPTER 3 AWARD BIOS SETUP
In this case, the PCI VGA controller should not respond to the W rite, it
should only snoop the data and permit the access to be forwarded to the ISA
bus. The non-VGA ISA graphic controller can then snoop the data on the ISA
bus. Unless you have the above situation, you should disable this option.
Disabled (default) Disables the function

CHAPTER 3 AWARD BIOS SETUP
Resources Controlled By
By Choosing “Auto” the system BIOS will detect the system resource and automatically assign the relative IRQ and DMA Channel for each
peripheral.
By Choosing “Manual”(default), the user will need to assign IRQ &
DMA for add-on cards. Be sure that there is no conflict IRQ/DMA and I/O
ports.
Note: when choosing “Auto” you must be sure that all of the system add-
on cards are PnP type.
Reset Configuration Data
The system BIOS supports the PnP feature so the system needs to
record which resource is assigned and protect resources from conflict.
Every peripheral device has a node which is called ESCD. This node records
which resources are assigned to it. The system needs to record and update
ESCD to the memory locations. These locations (4K) are reserved at the
system BIOS.
If Disabled (default) is chosen the system’ s ESCD will update only
when the new configuration varies from the last one.
If Enabled is chosen the system will be forced to update ESCDs if the
system configuration has changed and then auto set this option to the
“Disabled” mode.

The above settings will be shown on the screen only if “Manual” is
chosen for the Resources Controlled By function.
Legacy is the term which signifies that a resource is assigned to the
ISA Bus and provides for non PnP ISA add-on card. PCI/ISA PnP signifies
that a resource is assigned to the PCI Bus or provides for ISA PnP add-on
cards and peripherals.

to set up the passwords for both Supervisor and User are as follow:
1. Choose “Change Password” in the Main Menu and press <Enter>.
The following message appears:
“Enter Password:”
2 .The first time you run this option, enter your password up to only 8
characters and press <Enter>. The screen does not display the entered
characters. For no password just press <Enter>.
3. After you enter the password, the following message appears prompting
you to confirm the password:
“Confirm Password:”
4 .Enter exact the same password you just typed again to confirm the
password and press <Enter>.
5. Move the cursor to Save & Exit Setup to save the password.
6. If you need to delete the password you entered before, choose the
Supervisor Password and press <Enter>. It will delete the password that
you had before.
7. Move the cursor to Save & Exit Setup to save the option you did, other-
wise the old password will still be there when you turn on your machine
next time.
