BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the Phoenix-Award™
BIOS Setup program on this motherboard. The Setup program allows users to
modify the basic system configuration and save these settings to CMOS RAM.
The power of CMOS RAM is supplied by a battery so that it retains the Setup
inform ation when the power is turned off.
Basic Input-Output System (BIOS) determines what a computer can do without
accessing programs from a disk. This system controls most of the input and
output devices such as keyboard, mouse, serial ports and disk drives. BIOS
activates at the first stage o f the booting process, loading and executing the
operating system. Some additional features, such as virus and password
protection or chipset fine-tuning options are also included in BIOS.
The rest of this manual will to guide you through the options and settings in
BIOS Setup.
Plug and Pla y Support
This PHOENIX-AWARD BIOS supports the Plug and Play Version 1.0A
speci fication and ESCD (Extended System Configuration Data) write.
