Introduction

The P55-KVmainboard is a high performance system hardware based on

Intel Pentium processor and is equipped with two PCI slots, three standard

ISAslots,SuperMulti-I/OcontrolleranddualportPCI-IDEconnectorsfor

thefutureexpansion.Thehardwaredimensionis220mmx190mmwitha

four-layer-design technology.

Specification

VIAVT82C580VPXPCIsetchipset.

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

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

(72PinsSIMMx2). BIOSwillautometicallydetectandconfigureFPDRAM

andEDODRAM(RefertoChapter 2-4SystemMemoryConfiguration).

Supports Onboard Pipelined Burst (synchronous) L2WriteBack Cache.

Thecachememorycombinationcanbe256KB/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

PIOMode3andMode4devices.TheP55-KVsupportstwoPCIBus

Masters and a jumperless PCI INT# control scheme which reduces configu-

rationconfusion whenplugginginPCII/Ocontrollercard(s).

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

Supports 1 floppy port, 1 parallel port (EPP,ECP port), and 2 serial ports

(16550FastUARTcompatible).

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).

TheP55-KVisdesignedwithVIA82C580VPXPCIsetchipsetwhichisdeveloped

by VIA Corporation to fully support Pentium Processor PCI/ISA system. The VIA

82C580VPXPCIsetchipsetprovidesincreasedintegrationandimprovedperformance

designs. The chipset provides an integrated IDE controller with two high perfor-

mance IDE interfaces for up to four IDE devices (hard devices, CD-ROM device, etc).

The Winbond W83877F Super I/O controller provides the standard PC I/O functions

including:floppyinterface,two16ByteFIFOserialportsandEPP/ECPcapable

parallel port. TheP55-KV layout is shown in the previous page (left page) for user's

reference.Caremustbetakenwheninsertingmemorymodules,insertingCPUor

even plugging PCI cards into the associated slots to avoid damaging any circuits or

sockets on board. A cooling fan is strongly recommended when installing P54C/

The P55-KV supports standard Fast Page and EDO (Extended Data Out or Hyper

Page Mode) .TheP55-KVprovides two 72-pin SIMM for memory expansion. The

socketssupport1Mx32(4MB),2Mx32(8MB),4Mx32(16MB),and8Mx32(32MB)

single-sided or double-sided memory modules. The memory timing requires 70 ns

Fast page devices or 60 ns EDO DRAM. (DRAM Modules may be parity[x 36] or

non-parity[x32].

TheP55-KV supportsOnboardtwoPCIIDEconnectorsandBIOSdetectsIDE

The P55-KVsupports Award Plug & Play BIOS for ISA and PCI cards. The BIOS

can be located in Flash EPROM which is a technology to easily revise/upqrade BIOS

through software.

MemoryConfigurationTable

NOTE : 1. P55-KV supports both Fast Page DRAM and EDO DRAM SIMMs, but

they cannot be used in different SIMM at the same time.

2-3 System Memory Configuration

The P55-KV supports different type of settings for the system memory. The

following table provides all possible memory combinations.

SIMM1

SIMM2

Note 1 : If the Cyrix M1(6x86) is installed on the P55-KV mainboard, one of

the two types of cooling fans(Model NO. 20750 is a normal /standard fan/

heatsink. Model NO. 20832 is a 90 degree rotated fan.) must be selected

correctly to match the regulator heatsink direction. The P55-KV requires the

use of Model NO : 20832.(Customer should request a NMB-B50 fan). Please

Contact the Cyrix CPU suppliers for the details.

Note 2 : If the Cyrix 6x86L-P200+ is installed on the P55-KV mainboard,

there is a limitation : It cannot work properly with the PCI 2.0 SCSI card,such

as Adaptec AHA-2940/3940. For instance, the system will hang up or the data

in the harddisk winn be damage. However, you may use PCI 2.1 SCSI card, such

as AHA-2940AU/UW, because it work well with the CPU.

2-6 P55-KV

2-4 Cache Memory Configuration

The second level (L2) of cache is installed in the mainboard to increase the system

performance. The P55-KV supports two types of combinations for the cache

installation. Please refer to the following configurations for the details.

TheP55-KV utilizesVIA82C580VPXPCIsetchipset to supportIntelPentium

Processor PCI/ISA system. The VIA 82C580VPX PCIset chipset consists of one

82C585VPXsystemcontroller(TSC),two82C587VPDataPath(TDP)devices,and

one82C586APCIISA/IDE Acceleratorbridgechip.Itprovides aninterfacewhich

translates CPU cycle into PCI bus cycle and PCI burst read/write capability. In

addition, it provides high performance PCI arbitor to support two PCI Masters,

RotatingPriorityMechanism,andHiddenArbitrationSchemeMinimizesArbitration

Overhead.

Therearefourinterruptsin eachPCIslot:INTA#,INTB#, INTC#,andINTD#.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. You do not

have to configure jumpers or worry 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 plug paddle card and cable into the ISA slot.)

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

no paddle card and cable (refer to user's manual of the card) to a proper system IRQ

level (In general, the 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 (marked PCI#2) because the Secondary INT signal takes INTB from the slot

(refertoPage3-12forcircuitdiagram).TheuserthenentersPCICONFIGURATION

The menu displays all the major selection items. Select the item you need to

reconfigure. The selection is made by moving cursor (press any direction key ) to the

item and press the 'Enter' key. An on-line help message is displayed at the bottom of

the screen as the cursor is moving to various items which provides a better under-

standing of each function. When a selection is made, the menu of selected item will

appear so the user can modify associated configuration parameters.
