Introduction

The EP-5ATXA-M mainboard is a high performance system hardware

based on Intel Pentium processor and is equipped with four PCI slots, four

standard ISA slots, a PnP Super I/O controller and two dual-port PCI-IDE

connectors for the future expansion. The hardware dimension is an ATX

form-factor that is 208mm x 305mm with a four-layer design technology.

Specification

Intel 82430TX PCIset chipset.

Intel Pentium Processor, Pentium Processor with MMX

technology,

AMD K5/K6 and Cyrix 6x86/6x86L/6x86MX operating at 90 ~ 333 MHz(Easy

CPU CLK Setting JP3 : One Jumper Only) with 321ZIF socket 7 provides

scalability to accept faster processors in the future.

Supports an onboard Switching Voltage Regulator to increase CPU and

systems reliability.

Supports CPU Vcore Voltage 2.0V/2.2V/2.8V/2.9V/3.2V selection.

Supports up to 256 MegaBytes of DRAM (a minimum of 8 MB) on board (72-

Pin SIMM x 2 and 168-Pin DIMM x 3). BIOS will autometically detect and

configure FP DRAM, EDO DRAM and SDRAM (Refer to Chapter 2-4,

System Memory Configuration).

Supports Onboard Pipelined burst synchronous L2 Write Back Cache. The

cache memory is 512KB (64KB*32 SRAM).

Supports four 16-bit ISA slots and four 32-bit PCI slots and provides two

independent high performance PCI IDE interfaces capable of supporting PIO

Mode 3 and Mode 4 devices.

Supports ATAPI (e.g. CD-ROM) devices and Ultra DMA 33 Harddisk for

both IDE interfaces.

Supports 1 floppy port, 1 parallel port (EPP,ECP port), and 2 serial ports

(16550 Fast UART compatible) with PnP Super I/O chip.

Supports both PS/2 style mouse and PS/2 style AT keyboard connectors.

Supports Award Plug & Play BIOS. The BIOS is stored in Flash EPROM

form. It provides better upgradeability for the system.

Supports a CPU Hardware sleep and SMM (System Management Mode)

function.

Supports a PWR/ON connector with an ATX power supply for a Remote ON/

OFF controller, a Ring-in (External Modem only) Power-ON and a Keyboard

Power-ON and Mouse Power-ON function.
