4-1 Introduction
This chapter describes the Phoenix BIOS™ Setup utility for the X7SBi-LN4/X7SBi-
LN4-TM. The Phoenix ROM BIOS is stored in a flash chip and can be easily up -
graded 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 the Manual Download area of the Supermicro web site <http://www.
supermicro.com> for any changes to the BIOS that may not be reflected
in this manual.
System BIOS
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 when
the computer is powered on, the computer is configured with the values stored in
the CMOS logic 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 accessed by pressing
the <Delete> key at the appropriate time during system boot. 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. Beginning
with Section 4-3, detailed descriptions are given for each parameter setting in the
Setup utility.
