Introduction

The P55-VP 2mainboard is a high performance system hardware based

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

standardISAslots,SuperMulti-I/O controlleranddual portPCI-IDE

connectorsforthefutureexpansion.Thehardwaredimensionis220mmx

Specification

VIAApolloVPXPCIsetchipset.

Intel Pentium Processor, AMD K5/K6 & Cyrix M1 operating at75 ~ 200

MHz andP55C with321 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-pinSIMMx4&168-pinDIMMx1). BIOSwillautometicallydetectand

configure FP/EDO and Synchronous DRAM (Refer to Chapter 2-3 System

MemoryConfiguration).

Supports Onboard Pipelined Burst (synchronous) L2WriteBack/Through

Cache.Thecachememorycombinationcanbe256KB/512KB(32KB*32,

64KB*32SRAM,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

PIOMode3/4andUltra-DMA33devices.TheP55-VP2supportsthreePCI

Bus Masters and a jumperless PCI INT# control scheme which reduces

configurationconfusion whenplugging in PCI I/O controller card(s).

SupportsATAPI(e.g.CD-ROM)devicesonbothIDEinterfaces.

Supports1floppyport,1parallelport(EPP,ECPport), 2 serial ports (16550

FastUARTcompatible)and1USB Connector.

Supports a PS/2 style mouse and standard AT style keyboard connectors.

SupportsAwardPlug & Play BIOS . TheBIOS is stored in Flash EPROM

form. It provides better upgradeability for the system.

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

P55-VP2utilizes Lithiumbatterywhichprovidesenvironmentalprotection

TherearefourinterruptsineachPCIslot:INTA#,INTB#,INTC#,andINTD#.Since

the P55-VP 2adapts the PCI auto-configuration with the system BIOS Setup utility.

Whenthesystemis turned on after adding a PCI add-incard,theBIOS automatically

configure interrupts, DMA channels, I/O space, and other paramaters. You do not

have to configure jumpers or worry about potential resource conflicts. Because PCI

cards use the same interrupt resource as ISA cards, you must specify the interrupt

used by ISA add-in cards in the BIOS Setup utility.

However, if a "Legacy card" (such as plugging a paddle card and cable into an ISA

slot)ispluggedinthesystem,modificationinthe ROMSETUPUTILITYbecomes

necessary.Firstofall,youmustenterPCICONFIGURATIONSETUPutilityfrom

You can set the system interrupt request (IRQ) on some "Legacy cards" which have

on paddle card and cable. (refer to user's manual of the card) to a proper system IRQ

level (In general, card's Primary is assigned to INTA and Secondary is assigned to

INTB). If the card is plugged into slot 1(marked PCI#1), you cannot use second slot

(markedPCI#2) becausetheSecondaryINTsignaltakesINTBfromtheslot(refer to
