Introduction

The P55TV2mainboard is a high performance system hardware based on

Intel Pentium processor and is equipped with four PCI slots, four standard

ISAslots, Ultra I/O controllerand dual port PCI-IDEconnectors for the

futureexpansion.Thehardwaredimensionis220mmx260mmwithafour-

layer-design technology.

Specification

Intel 82430VX PCIset chipset.

Intel Pentium Processor, Pentium Processor with MMX technology,

AMD K5/K6 and Cyrix M1/M2 operating at 90 ~ 266 MHz with 321 ZIF

socket 7 provides scalability to accept faster processors in the future.

Supports up to 128 MegaBytes of DRAM (a minimum of 8 MB) on board

(72 Pins SIMM x 4, 168 Pins DIMM x 2). BIOS will autometically detect

and configure FP DRAM, EDO DRAM and SDRAM (Refer to Chapter 2-

3, System Memory Configuration).

Supports Onboard Pipelined Burst synchronous L2 Write Back Cache.

The cache memory combination can be 256KB/512KB (32KB*32 and

64KB*32 SRAM, respectively).

Supports four 16 bits ISA slots, four 32 bits PCI slots, and provides two

independent high performance PCI IDE interfaces capable of supporting

PIOMode3andMode 4 devices. TheP55TV2supportsfourPCIBus

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

rationconfusionwhenpluggingin PCII/Ocontrollercard(s).

Supports AT API (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 2 USB ports.

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 upgradability for the system.

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

The P55TV2 supports two 168-pin DIMM module sockets to extpand system

memory size.You can install (3.3V/Unbuffered) Fast Page, EDO or

Synchronous DRAM. Besides, to support 5V FP and EDO DRAM with DIMM

socket, the P55TV2 provides JP1 to allow user using 3.3V/Unbuffered DIMM

module with 5V FP and EDO DRAM chips. The setting of the JP1 as follow:

When you plug a DIMM module into a 168-pin dual readout socket, you must

make sure that the key zoom of the DIMM module is 3.3V/Unbuffered and

supports Intel Pentium Processor System.
