7-1 Introduction
This chapter describes the Phoenix BIOS™ Setup utility for the NovaScale R422 X7DBT/
X7DBT-INF motherboard. The Phoenix ROM BIOS is stored in a fl ash chip and can be
easily upgraded using a fl oppy disk-based program.
System BIOS
The BIOS is the Basic Input Output System used in all IBM
®
PC, XT™, AT
®
, and PS/2
®
compatible computers. The Phoenix BIOS stores the system parameters, types of disk
drives, video displays, etc. in the CMOS. The CMOS memory requires very little electrical
power. When the computer is turned off, a backup battery provides power to the CMOS
logic, enabling it to retain system parameters. Each time the computer is powered on the
computer is con fi gured with the values stored in the CMOS Logic by the system BIOS,
which gains control at boot up.
How To Change the Con fi guration Data
The CMOS information that determines the system parameters may be changed by entering
the BIOS Setup utility. This Setup utility can be accessed 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. Beginning with Section 7-3 , detailed descriptions are given for each
parameter setting in the Setup utility.
WARNING:
To prevent possible boot failure, do not shut down or reset the system while updating BIOS.
!
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.
