Introduction

This chapter describes the PhoenixBIOS™ Setup utility for the motherboard.
The Phoenix ROM BIOS is stored in a flash chip and can be easily upgraded
using a floppy disk-based program.
Note: Due to periodic changes to the BIOS, some settings may have been
added or deleted and might not yet be recorded in this manual. Please refer
to our web site (http://service.advantech.com.tw/eservice) for any changes
to BIOS that may not be reflected in this manual.
System BIOS
The BIOS is the Basic Input Output System used in all IBM
®
PS/2 compatible computers. The PhoenixBIOS flash chip stores the system
parameters, such type of disk drives, video displays, etc. in the CMOS. The
CMOS memory requires very little electrical power. When the computer is
turned off, a back-up battery provides power to the BIOS flash chip, en-
abling it to retain system parameters. Each time the computer is powered-on
the computer is configured with the values stored in the BIOS ROM by the
system BIOS, which gains control at boot-up.
How To Change the Configuration Data
The CMOS information that determines the system parameters may be
changed by entering the BIOS Setup utility. This Setup utility can be ac-
cessed by pressing the <Delete> key at the appropriate time during system
boot, see below.
Starting the Setup Utility
Normally, the only visible POST (Power On Self Test) routine is the memory
test. As the memory is being tested, press the <Delete> key to enter the
main menu of the BIOS Setup utility. From the main menu, you can access
the other setup screens, such as the Security and Power menus.
ning with Section 4-3, detailed descriptions are given for each parameter
setting in the Setup utility.
