The 586VXD, equipped with a 321-pin Zero Insertion Force (ZIF) CPU
socket, is a Pentium processor-class system board supporting Intel
Pentium
processor with MMX
TM
technology - 166/200/233MHz and
Intel Pentium
processors running at 75MHz, 90MHz, 100MHz,
120MHz, 133MHz, 150MHz, 166MHz and 200MHz frequencies. The
586VXD also supports Cyrix
6x86
TM
PR120+/PR133+/PR150+/PR166+
and AMD-K5
TM
PR75/PR90/PR100/PR120/PR133/PR166 and K6/166
processors.
The 586VXD can support 8MB to 128MB of system memory. It is
equipped with 4 SIMM sockets using EDO or fast page mode x32
DRAM. Your system board may also come with a DIMM socket that
uses x64 EDO, fast page mode or SDRAM. The 586VXD also supports
256KB or 512KB pipeline burst SRAM and provides easy cache
upgrades using a 256KB cache module.
The 586VXD design is based on the Peripheral Component Intercon-
nect (PCI) local bus and Industry Standard Architecture (ISA) stan-
dards. It is equipped with 4 dedicated PCI slots and 3 dedicated 16-bit
ISA slots.
The 586VXD board has two bus master PCI IDE connectors. Bus mas-
tering reduces 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 controller, one PS/2 mouse port,
one PS/2 or AT keyboard connector, two connectors for external USB
ports and one IrDA connector for wireless connectivity between your
computer and peripheral devices.
