1) When you install ATX power supply, please connect CASE
STANDBY to front panel connector CN9/JP9 , pin 19-20
Power On. Then turn on ATX power supply.
2) The difference between TX2 and TX3 is that TX3 is without
SCSI port/chip. Others are the same.

Preface
Inside the Document
This document describes setup ATX586 Dual Pentium Main Board with
Intel 430TX PCI CHIPSET, resulting in Ultra IDE performance.
ATX586 is for ATX platform with dual processors design, including
Enhance I/O chip (SMC 669 compatible). There is an option that
installing “82093AA”supports two Intel Pentium (MMX) CPU, said
Dual Processors. Under single processor, the user installs Intel
Pentium 75-233Mhz, MMX, AMD K5/K6-PR 233, CYRIX CX6x86 200+.
Excepting above mentioned, ATX586 is designed with Auto
Switching between 3.3v and 2.8v CPU (when you use single CPU
only), front panel connector and Smart Jumper Setting for
different CPU.
The package for ATX586 including:
þATX586 mother board
þTwo IDE drive ribbon cable for 4 devices
þOne Floppy ribbon cable for 2 devices
þOne Ultra IDE device disk
þThis user’s manual
Chapter 1 is about positions, jumpers and connectors for
ATX586. Due to the board supports full range of Pentium CPU MMX
75Mhz-233Mhz, AMD K5/K6-PR233, CYRIX 6x86 CX 200+.
Chapter 2 is for BIOS setup. If you want to use external I/O card,
you can disable the I/O function in BIOS and then install a card on slot.
You also modify the COM1 and COM2 as COM3 and COM4 in
BIOS. Finally, the BIOS is PnP function. It auto detects the PCI
IRQ, ISA IRQ and HDD mode. Chapter 3 is for IDE DRIVER
installation and how to upgrade BIOS.

(Chapter 4 is about positions, jumpers and connectors for TX2.
Due to the board supports full range of Pentium CPU MMX 75Mhz-
233Mhz, AMD K5/K6-PR233, CYRIX 6x86 CX 200+.)

interrupt related traffic from the memory bus.

8
²24 Programmable Interrupts: 13 ISA supported; 4 PCI; 1 interrupt/
SMI# rerouting; 2 motherboard ; 1 interrupt used for INTR input; 3
general purpose; independently programmable for edge/level
sensitivity interrupts; each interrupt can be programmed to
respond to active high or low inputs.

When you want to install two CPU, they are perfect are the same
voltage 2.8v (P55C) or 3.3v(P54C). Different voltage can’t be
used together. Installing the 1st CPU at U4 socket!

1.4 Install System DRAM Memory
The board supports 2pcs 72-pin, 32-bit SIMMs (Single Inline Memory
Modules) and 2pcs 168-pin, 64-bit DIMM (Dual Inline Memory Modules)
of 4, 8, 16, 32MB to form a memory size between 8MB to 128MB.
The SIMMs can be 60ns or 70ns Fast Page Mode (FPM), or Enhanced
Data Out (EDO) (BEDO & Parity are not supported). SIMMs must
be installed in pairs so that each bank (see Map of ATX-586)contains
64-bit of same memory chips.
DIMM can be used as one bank. It is available for 3.3v (power level)
Unbuffered Synchronous DRAM (SDRAM) or EDO DRAM of either 8,
16, 32, 64, 128MB, to form a memory size between 8MB to 128MB.
SIMM and DIMM can be used together, but the limitations are two
banks and max memory size 128MB. 2pcs 72-pin SIMM is one bank
and 1pce DIMM is one bank too.
