Overview
The VT82C580VPX mainboard combines the advanced
capabilities of the VIA Apollo VPX chipset with a high
performance concurrent PCI local bus architecture to provide
the ideal platform for unleashing the unsurpassed speed and
power of the Intel Pentium
processor, Cyrix
6x86 and
AMD
K5/K6 processors, and can be easily upgraded for 321
pin ZIF socket.
The processor's advanced performance is complemented by a
second level write back PB-SRAM up to 1024KB and main
memory up to 512MB RAM. The main memory is initialed
using the board's two 72-pin SIMM sockets and two 168-pin
DIMM sockets that accept either the new high performance
EDO, BEDO, Fast Page mode DRAM, or synchronous
DRAM(SDRAM).
The VT82C580VPX integrates a full set of I/O features on
board, including two 16550 UART compatible serial ports, one
EPP/ECP capable port, one floppy disk controller, and one
infra-red communication controller. On chip built in Enhanced
IDE controller provides convenient, high speed PCI bus Master
connection capable of four IDE devices, including Hard disk
and CD-ROM.
