The 586IHX, 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 586IHX also supports
future Pentium OverDrive processors, Cyrix
6x86 and 6x86L P120+/
P133+/P150+/P166+ and AMD-K5 PR75/PR90/PR100/PR120/PR133
CPUs.
The 586IHX 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 checking
which informs the user of memory failures and prevents error accumula-
tion. The system board also supports 256KB or 512KB pipeline burst
SRAM and provides easy cache upgrades using a 256KB cache
module.
The 586IHX design is based on the Peripheral Component Interconnect
(PCI) local bus and Industry Standard Architecture (ISA) standards. It is
equipped with 3 dedicated PCI slots, 3 dedicated 16-bit ISA slots and 1
shared PCI/ISA slot.
The 586IHX is equipped with two NS16C550A-compatible serial ports,
an SPP/ECP/EPP parallel port, a floppy disk drive controller, and two
PCI IDE connectors with bus mastering capabilities that highly reduce
CPU use during disk transfer. This system board is also equipped with
one PS/2 mouse port, one PS/2 keyboard port, two connectors for ex-
ternal USB ports and one IrDA connector for wireless connectivity be-
tween your computer and peripheral devices.
The 586IHX system board is designed to fit into an ATX form factor
case. Using an ATX power supply, you can either shut down your com-
puter by pressing the Power button located on the front bezel of your
computer or by executing the Shut Down command under the Windows
95 operating system.
