System Memory Configuration

This 82430TX motherboard supports 72-pin SIMMs and
168pin DIMM (3.3V unbuffered type) of 4MB, 8MB, 16MB,
or 32MB to form a memory size between 4MB to 256MB
(total of 6 rows are supported).

The 82430TX chipset supports ÒTable FreeÓ configuration so
that DRAM module can be installed at any capacity except

SIMM1, 2 and SIMM 6 canÕt be installed at the same time.

receiving. Pin 6 through 10 are Transmit, GND, Receive

(low speed), Receive (high speed), and Vcc, respectively.

J1 pin12, 13: Power Switch

Connect the ATX power switch to this connector.

SMI Switch (J1 pin14, 15)

Toggle this jumper forces the system to sleep and the system
wonÕt wake up until the hardware event is coming. (The
BIOS Power Management setting muse be Enabled.)

Speaker Connector (J2 pin1–4)

The speaker connector is a 4-pin connector for connecting
the system and the speaker. (See the following drawing for
jumper position.)

Reset Switch (J2 pin5, 6)

The system board has a 2-pin connector for rebooting your
computer without having to turn off your power switch.
This prolongs the life of the systemÕs power supply.

Power LED and Keylock Switch (J2 pin8–12)

The keylock switch is a 5-pin connector for locking the
keyboard for security purposes. (See the following drawing
for jumper position, and pin1~3 is connected to power LED
and pin 4~5 is connected to keylock switch.)

DRAM Leadoff
Timing

Use the default setting. This sets the
point of time that the CPU is
allowed to read and write to DRAM
and then perform.

DRAM Read Burst
DRAM Write Burst
Timing
(EDO/FPM)

Use the default setting. Burst
read/write requests are generated
by the CPU in four separate parts.
The 1st part provides the location
within the DRAM where the read or
write is to take place while the
remaining three parts provide the
actual data. The lower the timing
number is, the faster the system
memory will be addressed.

Fast EDO Lead Off Use the default setting. This

function allows you to enhance the
performance by selecting the Fast
EDO Lead Off.

Refresh RAS#

type of DRAM refresh clock delay.

Use the default setting. This setup
option allows you to determine the
delay time in completing the
transition from RAS to CAS.

Use the default setting. Choices are
2, 4, 6, or 8 clk.

This function allows you to
determine either to keep the page
open until a page/row missing or to
use the additional information to
keep the DRAM page open when
the host may be right back.

8 Bit I/O Recovery
Time Select Item

16 Bit I/O Recovery

Use the default setting. This
function allows a DRAM read
request to be generated slightly
before the address has been fully
decoded.

Choose Enabled or Disabled
(default). When Enabled, the access
to the system BIOS ROM addressed
at F0000H-FFFFFH is cached.

Choose Enabled or Disabled
(default). When Enabled, the access
to the VGA BIOS ROM addressed at
C0000H-C7FFFH is cached.

This delay happens when the CPU
is running so much faster than the
I/O bus that the CPU must be
delayed to allow for the completion
of the I/O.

The choices for 8 bit I/O are NA, 1
to 8 CPU clock. Default is 3.
The choices for 16 bit I/O are NA, 1
to 4 CPU clock. Default is 2.

Memory Hole At
15M-16M

Choose Enabled or Disabled
(default). In order to improve
performance, certain space in
memory can be reserved for ISA
cards. This memory must be
mapped into the memoryÕs space
below 16MB.

PCI 2.1

functions, choose No otherwise.

Video Off Method Choose Blank , DPMS, or V/H

Sync+Blank (default). You can
chose either DPMS or V/H
Sync+Blank when the monitor has
the Green function. You need to
choose Blank when the monitor
does not have the Green function.

Note: Some VGA cards donÕt allow

V/H Sync to be turned off
directly.

Video Off After Choose N/A (default), Doze,

Standby, or Suspend. This function
determines the timing of the
monitor closed down functions.

Doze Mode This option sets the CPU speed

down to 33MHz during this mode.

Standby Mode
Suspend Mode

These two options allow you to
choose the mode for the different
timers. The Standby Mode turns off
the VGA monitor, and the Suspend
Mode turns off the CPU and saves
the energy of the system.

HDD power Down Time is adjustable from 1 to 15

minutes. When the set time has
elapsed, the BIOS sends a command
to the HDD to power down, which
turns off the motor.

Throttle Duty

Choose the duty cycle time: 12.5%,
25%, 37.5%, 50%, 62.5% (default),
75%, or 87.5%. The bigger of the
