Introduction
System Overview
This manual was written to help you start using this product
as quickly and smoothly as possbile. Inside, you will find
the answers to solve most problems. In order for this
reference material to be of greatest use, refer to the
“expanded table of contents” to find relevant topics.
This board provides a total PC solution by incorporating the
System , I/O , and PCI IDE. The mainboard support single
Intel P4 processors base PC ATX system, PCI Local Bus,
and AGP Bus to upgrades your system performance.
It is ideal for multi-tasking and fully supports MS-DOS,
Windows, Windows NT , Windows ME, Windows 2000,
Novell, OS/2, Windows95/98, Windows 98SE, Windows XP,
Liunx, UNIX, SCO UNIX etc.
This manual also explains how to install the mainboard for
operation, and how to setup your CMOS configuration with
the BIOS setup program.
