The EP-5BTXA-E
mainboard is a high performance system hardware
based on Intel Pentium processor and is equipped with three PCI slots, three
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 AT form-
factor that is 220mm x 200mm with a four-layer design technology.
Specification
Intel 82430TX PCIset chipset.
Intel
Pentium
Processor operating at
90 ~ 333 MHz
(Easy CPU CLK
Setting JP3 : One Jumper Only) and
P55C
with
321 ZIF socket 7
for
scalability to accept faster processors in the future.
Supports an onboard Switching Voltage Regulator to increase CPU and
System's reliability.
Supports CPU Vcore Voltage 2.0V/12.1V/2.8V/2.9V/3.2V selection.
Supports up to 256 MegaBytes of DRAM(a minimum of 8 MB) on board
(168-Pin DIMM x 2), BIOS auto EDO DRAM and SDRAM
configuration.(Refer to Chapter 2-4 System Memory Configuration)
Supports Onboard Burst/Pipelined burst synchronous L2
Write Back
Cache. The cache memory is 512KB (64KB*64 SRAM).
Supports three 16-bit ISA slots and three 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 for both IDE
interface.
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 Header and AT keyboard connector
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 USB header
Utilizes a Lithium battery which provides environmental protection and
longer life-time
