Page: 5 / 67

The G586VPS Pro design is based on the VLSI Lynx system controller

chipset. It is equipped with a 321-pin Zero Insertion Force (ZIF) CPU

socket to support various Intel

Pentium and Cyrix

6x86 CPUs.

The G586VPS Pro supports 8MB to 256MB of system memory using

EDO or fast page mode DRAM. It is equipped with 4 SIMM sockets

allowing you to install x32 or x36 SIMM. The x36 SIMM supports parity

checking which informs the user of memory failure and prevents error

accumulation. The system board also supports 256KB or 512KB fast

pipeline burst cache.

The G586VPS Pro system board has two PCI IDE connectors with bus

mastering capabilities that highly reduce CPU use during disk transfer.

This system board is also equipped with two NS16C550A-compatible

serial ports, an SPP/ECP/EPP parallel port, a floppy disk drive control-

ler, one PS/2 mouse port, one PS/2 or AT keyboard connector and one

IrDA connector for wireless connectivity between your computer and pe-

ripheral devices.
