The C586HX, equipped with a 321-pin Zero Insertion Force (ZIF) CPU
socket, is a Pentium processor-class system board supporting Intel
Pentium CPUs running at 75MHz, 90MHz, 100MHz, 120MHz, 133MHz,
150MHz, 166MHz and 200MHz frequencies. The C586HX also supports
Cyrix P120+/P133+/P150+/P166+ and AMD-K5 PR75/PR90/PR100
CPUs.
The C586HX 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 SIMMs. The x36 SIMM supports parity check-
ing which informs the user of memory failure and prevents error accu-
mulation. The system board also supports 256KB or 512KB pipeline
burst SRAM and provides easy cache upgrades using a 256KB cache
module.
The C586HX design is based on the Peripheral Component Intercon-
nect (PCI) local bus and Industry Standard Architecture (ISA) stan-
dards. It is equipped with 3 dedicated PCI slots, 3 dedicated 16-bit ISA
slots and 1 shared PCI/ISA slot.
The C586HX 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 USB connectors and one IrDA
header for wireless connectivity between your computer and peripheral
devices.
