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+.)
Simple features:
²Intel 430 TX PCISET. 82439TX System Controller (MTXC),
82371AB PIIX4 PCI to ISA / IDE Xcelerator, 82093AA I/O
Advanced Programmable Interrupt Controller (IOAPIC).
²Compatible SMC 669 super I/O on board.
²Supports full range of Pentium Processor Family, up to Intel
Pentium MMX-233Mhz, AMD K6-PR-233, CX 6x86 200+. There
is an auto- switching mode from 3.3v to 2.8v.
²Installing (option) 82093AA to let the board supports two
Intel Pentium or MMX CPU at the same board for ATX586.
It is perfect to run the same voltage CPU!
²Support SDRAM/EDO/Fast page DRAM, 72-pin SIMM socket *
4pcs, 168-pin DIMM socket * 2pcs. 2 pairs/4 banks up to
256MB. 6-1-1-1 for SDRAM; 5-2-2-2 for EDO; 6-3-3-3 for FP.
²64-MB DRAM cacheability. Direct Mapped organization-write
back only. Supports 256K and 512K Pipelined Burst SRAM.
²PCI V2.1 compatible. Concurrent PCI, enhanced CPU/PCI/ISA
performance.
²Provides Multiprocessor Interrupt Management: dynamic interrupt
distribution routing interrupt to the lowest priority processor;
software programmable control of interrupt inputs; off loads
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.
²4 * 32-bit PCI, 4 * 16 bit ISA Slots for ATX586
²2 * Ultra EIDE,support 4 IDE devices. EPP/ECP/SPP printer port.
2 * 16550 UART serial ports. PS/2 mouse port. IR, infrared, port,
option for FIR, fast infrared. 2 * USB, universal serial bus, ports.
²IDE controller: Independent timing of up to 4 drives. PIO mode
4 transfers up to 14 Mbytes/sec. Supports “Ultra 33”synchronous
DMA mode transfers up to 33 Mbytes/sec. Integrated 8*32-bit
buffer for IDE PCI Burst transfers.
²Dual Power Supply. Has both AT and ATX power connectors
on board to support AT or ATX power supply with soft-on/off
features.
²Built-in AWARD PCI/ISA Plug and Play Flash BIOS GREEN
BIOS
²Two-mega flash recovery BIOS ROM.

Hardware
Installation For ATX586
1.1 One Jumper to Set CPU , Simple Jumper
No more CPU jumper setting when you use Single Processor
Intel 133Mhz,
CYRIX 166+,
AMD K5-133 CPU.
You just install CPU directly and Power On. (At the moment, JP6: 1-
2 and JP7: 2-3 SHORT; JP8/JP9: 1-2 SHORT )
A: Using Intel CPU (Ensuring JP8/JP9: 1-2 SHORT)
CPU Speed JP6 JP7
Intel 100Mhz 1-2 SHORT 1-2 SHORT
Intel 166Mhz 2-3 SHORT 2-3 SHORT
Intel 200Mhz 2-3 SHORT 1-2 SHORT
Intel 233Mhz 1-2 SHORT 1-2 SHORT
B: Using AMD K5/K6 (Ensuring JP8/9: 1-2 SHORT)
CPU Speed JP6 JP7
AMD K5-100 1-2 SHORT 1-2 SHORT
AMD K5/K6-PR-166 2-3 SHORT 2-3 SHORT
AMD K6-PR200 2-3 SHORT 1-2 SHORT
AMD K6-PR233 1-2 SHORT 1-2 SHORT
C: Using CYRIX 6x86 CPU ( Ensuring JP6: 1-2 and JP7: 2-3 SHORT)
CPU Speed JP8 JP9
CX 133+, 55Mhz 2-3 SHORT 2-3 SHORT
CX 150+, 60Mhz 2-3 SHORT 1-2 SHORT
CX 200+, 75Mhz 1-2 SHORT 2-3 SHORT
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!
