Chapter 1 System Board
Introduction
System Overview
The board incorporates system board, ISA I/O and PCI IDE in one board that provides all the PC solutions. The mainboard is a PentiumTM micro processor based PC/AT system, supports 512KB to 1M cache with ISA Bus and PCI Local Bus to upgrade your system performance. It is ideal for multi-tasking and fully supports MS-DOS, Windows, Windows NT, Novell, OS/2, Windows95, UNIX, SCO UNIX etc. This manual also explains how to install the mainboard for operation, and how to setup your CMOS configuration with BIOS setup program.

Provides 321-pin ZIF socket (socket 7).
Green Function
Supports power management operation via BIOS.Power down timer from 1 Min to 1 Hour.Wakes up by any keypress or mouse activity.
Speed
Supports CPU bus clock 60/66/75/83 MHz.Supports 30/33 MHz PCI Bus speed.
(when processors running at 75/83MHz, the clock generator divided it by 2.5 which makes PCI bus speed become 30/33 MHz respectively)
I/O clock 8 MHz for ISA Bus.

1. The SIMM slot has an “ Iron
Safety Tab” and the SIMM memory
module has a “Notched End”, so the SIMM memory module can only fit in one direction.
2. Insert the SIMM memory modules into the socket at 45-degree angle, then push
into a vertical position so that it snaps into place.
3. The Mounting Holes and Metal Clips should fit over the edges and hold the
SIMM memory modules in place.

Chapter 1 System Board
1. The DIMM slot has a “ Plastic Safety Tab” and the DIMM memory module has a “an asymmetrical notch”, so the DIMM memory module can only fit in one direction.
2. Push the tabs out. Insert the DIMM memory modules into the socket at 90-degree angle, then push down a vertical position so that it will snap into place.
3. The Mounting Holes and plastic tabs should fit over the edge and hold the DIMM memory modules in place.
