The P55-VP 2
mainboard is a high performance system hardware based
on Intel Pentium processor and is equipped with three PCI slots, four
standard ISA slots, Super Multi-I/O controller and dual port PCI-IDE
connectors for the future expansion. The hardware dimension is 220mm x
230mm with a four-layer-design technology.
Specification
VIA Apollo VPX PCIset chipset.
Intel
Pentium
Processor, AMD K5/K6 & Cyrix M1 operating at
75 ~ 200
MHz
and
P55C
with
321 ZIF socket 7
and scalability to accept faster
Processors in the future.
Supports up to 192 MegaBytes of DRAM (a minimum of 8 MB) on board
(72-pin SIMM x 4 & 168-pin DIMM x 1). BIOS will autometically detect and
configure FP/EDO and Synchronous DRAM (Refer to Chapter 2-3 System
Memory Configuration).
Supports Onboard Pipelined Burst (synchronous) L2
Write Back/Through
Cache
. The cache memory combination can be 256KB/512KB (32KB*32,
64KB*32 SRAM, respectively).
Supports four 16 bit ISA slots and three 32 bit PCI slots and provides two
independent high performance PCI IDE interfaces capable of supporting
PIO Mode 3/4 and Ultra-DMA33
devices. The
P55-VP 2
supports three PCI
Bus Masters and a jumperless PCI INT# control scheme which reduces
configuration confusion when plugging in PCI I/O controller card(s).
Supports
ATAPI
(e.g.
CD-ROM
) devices on both IDE interfaces.
Supports 1 floppy port, 1 parallel port (EPP,ECP port), 2 serial ports (16550
Fast UART compatible) and 1 USB Connector.
Supports a
PS/2
style mouse and standard AT style keyboard connectors.
Supports 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-VP 2
utilizes Lithium battery which provides environmental protection
and longer battery life.
