The P55-KV
mainboard is a high performance system hardware based on
R
Intel Pentium processor and is equipped with two PCI slots, three standard
ISA slots, Super Multi-I/O controller and dual port PCI-IDE connectors for
the future expansion. The hardware dimension is 220mm x 190mm with a
four-layer-design technology.
Specification
VIA VT82C580VPX PCIset chipset.
R
Intel Pentium Processor, AMD K5 & 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 128 MegaBytes of DRAM (a minimum of 4 MB) on board
(72 Pins SIMM x 2). BIOS will autometically detect and configure FP DRAM
and EDO DRAM (Refer to Chapter 2-4 System Memory Configuration).
Supports Onboard Pipelined Burst (synchronous) L2 Write Back Cache.
The cache memory combination can be 256KB/512KB (32KB*32, 64KB*32
SRAM, respectively).
Supports three 16 bit ISA slots, two 32 bit PCI slots, and provides two
independent high performance PCI IDE interfaces capable of supporting
PIO Mode 3 and Mode 4 devices. The P55-KV supports two PCI Bus
Masters and a jumperless PCI INT# control scheme which reduces configu-
ration 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), and 2 serial ports
(16550 Fast UART compatible).
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-KV utilizes Lithium battery which provides environmental protection
and longer battery life.

    There are four interrupts in each PCI slot : INTA#, INTB#, INTC#, and INTD#. Since the P55-KV adapts the PCI auto-configuration with the system BIOS Setup utility. When the system is turned on after adding a PCI add-in card, the BIOS automatically configure interrupts, DMA channels, I/O space, and other paramaters.
