AB2x280 F1 System BIOS
Introduction
This chapter describes the BIOS for AB2x280 F1blade modules. The
AB2x280 F1blade modules use a AMI™ ROM BIOS that is stored in a
flash chip. This BIOS can be easily upgraded using a floppy disk-based
program.
BIOS
BIOS stands for Basic Input Output System. The AMI BIOS flash chip
stores the system parameters, types of disk drives, video displays, etc. in
the CMOS. The CMOS memory requires very little electrical power.
When the blade unit is turned off, a backup battery provides power to
the BIOS flash chip, enabling it to retain system parameters. Each time
the blade is powered on it 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
accessed by pressing the key at the appropriate time during
system boot. (See "Starting the Setup Utility" 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 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.
Warning! To prevent possible boot failure, do not shut
down or reset the system while updating the BIOS.
