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
mod ify the bas ic s ystem co nfigur ation and save t hese settings to CMOS RAM.
The power of CMOS RAM is supplied by a battery so that it retains the Setup
info rmatio n when the po wer 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
outp ut devices suc h as keyboard, mous e, s erial po rts and disk drives . BIOS
activates at the first stage of the boo ting process, loading and executing the
operating system. Some additional features, such as virus and password
protectio n or c hipset 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 Play Support
This PHOENIX-AWARD BIOS supports the Plug and Play Version 1.0A
specification and ESCD (Extended System Configuration Data) write.
EPA Green PC Support
This PHOENIX-AWARD BIOS supports Version 1.03 of the EPA Green PC
specification.
APM Support
This PHOENIX-AWARD BIOS supports Version 1.1&1.2 of the Advanced
Power Management (APM) spec ific ation. Power management features are
implemented via the Sys tem Management Interrupt (SMI). Sleep and Suspend
power management modes are supported. Power to the hard disk drives and
video monito rs can also be managed by this PHOENIX-AWARD BIOS.

1 Main Menu
Once you enter Phoenix-Award BIOS™ CMOS Setup Utility, the Main Menu
will appear o n the screen. The Main Menu allo ws you to select from several
setup f unct ions. Use the arrow keys to select amo ng t he items and press <Enter>
to accept and enter the sub-menu.
!! WARNING !!
For better system performance, the BIOS firmware is being
continuously updat ed. The BIOS inf or mat ion d esc ribed in
this manual (Figure 1, 2, 3, 4, 5, 6, 7, 8, 9) is for yo ur
reference only. The actual BIOS information and settings on
board may be slightly different from this manual.
