The P55-TH
motherboard is a high performance system hardware
based on Intel Pentium processor and is equipped with four PCI slots, four
standard ISA slots, Super Multi-I/O controller and dual ports PCI-IDE
connectors for the future expansion. The hardware dimension is 220mm x
280mm with four layer design technology.
Specification
Intel
Pentium
Processor operating at
50/75, 60/90, 66/100, 60/120, 66/
133, 60/150, 66/166 MHz
and
P54C/P54CTB/P55C
with
321 ZIF
socket 7
and scalability to accept faster Pentium Processors in the feature.
Supports up to 512 MegaBytes DRAM(minimum of 8 MB) on board(72
Pins SIMM x 4), and BIOS auto DRAM/EDO RAM configuration.(Refer
to Chapter 2-3 System Memory Configuration)
Supports both Fast Page DRAM or
EDO
DRAM SIMM. Optional DRAM
Parity or Error Checking and Correction (ECC) with 72-bit Wide memory.
Intel 82430HX PCIset chipset.
Supports Onboard Pipelined burst synchronous and the
COAST(v2.0) or
later Version
solusion L2
Write Back
Cache. The cache memory
combination could be 256KB/512KB (32KB*32 or 64KB*32 SRAM
respectively).
Support four 16 bits ISA slots, four 32 bits PCI slots, and provides two
independent high performance PCI IDE interface capable of supporting
PIO Mode 3 and Mode 4
devices. The
P55-TH
supports four PCI Bus
Masters and a jumperless PCI INT# control scheme which reduces
configuration confusion when plug in PCI I/O controller card(s).
Supports
ATAPI
(e.g.
CD-ROM
) devices on both IDE interface.
Supports 1 floppy port(up to 2.88 MB), 1 parallel port (EPP,ECP port), and
2 serial port (16550 Fast UART compatible).
Supports a
PS/2
style mouse and standard AT style keyboard connectors.
Support Award Plug & Play BIOS . The BIOS is stored in Flash EPROM
form. It provides better upgradeability for the system.
Supports CPU Hardware sleep and SMM (System Management Mode).
P55-TH
utilizes Lithium battery which provides environmental protection
and longer life time.
