The 586TXD, equipped with a 321-pin Zero Insertion Force (ZIF) CPU
socket, is a Pentium
processor-class system board supporting Intel
Pentium
processors with MMX™
technology - 166/200/233MHz, Intel
Pentium
processors running at 90MHz, 100MHz, 120MHz, 133MHz,
150MHz, 166MHz and 200MHz frequencies, and future Intel
Pentium
OverDrive
processors. The 586TXD also supports AMD
K5™
PR90/
PR100/PR120/PR133/PR166, and AMD
K6/166, K6/200 and K6/233.
The 586TXD system board can support 8MB to 256MB of system
memory. It is equipped with two DIMM sockets using x64 EDO, fast
page mode or SDRAM, and 4 SIMM sockets using EDO or fast page
mode x32 DRAM. This system board also supports 512KB pipeline
burst SRAM.
The 586TXD 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, 2 dedicated 16-bit ISA slots and 1
shared PCI/ISA slot.
The 586TXD is equipped with two NS16C550A-compatible serial con-
nectors, an SPP/ECP/EPP parallel connector, a shrouded floppy disk
header, and two shrouded PCI IDE headers with bus mastering capa-
bilities that highly reduce CPU use during disk transfer. This system
board is also equipped with one PS/2 mouse connector, one PS/2 or AT
keyboard port, two USB ports and one IrDA connector for wireless con-
nectivity between your computer and peripheral devices.
The 586TXD system board is a Baby AT form factor board designed to
fit into an ATX form factor case. Using an ATX power supply, you can
either shut down your computer 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 if you have power
management in the BIOS setup correctly enabled. Your system will then
enter the “Soft Off” state. With a modem connected to your system, you
can power on your system to remotely transmit or access data. An ATX
