4-1 Introduction
This chapter describes the Phoenix BIOS™ Setup utility for the C2SBM-Q.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 the Manual Download area of the Super Micro web site
<http://www.supermicro.com> for any changes to the BIOS not reflected
in this manual.
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 pro-
vides power to the CMOS logic, enabling it to retain system parameters. Each time
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 during the POST (Power On Self Test) routine. From the main menu,
you can access the other setup screens, such as the Security and Power menus.
Beginning with Section 4-3, detailed descriptions are given for each parameter
setting in the Setup utility.
Warning:
Do not shut down or reset the system while updating the BIOS
to prevent possible boot failure.
