BIOS
5-1 Introduction
This chapter describes the BIOS for Intel SuperBlade modules. The Intel Blade modules
use a 16 Mb SPI Flash EEPROM with AMI® BIOS™ that is stored in a flash chip. This
BIOS 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 http://
www.supermicro.com/products/SuperBlade/module/ web site for further details on BIOS
setup and the BIOS menus for your SuperBlade blade module.
System BIOS
BIOS stands for Basic Input Output System. The 16 Mb SPI Flash EEPROM with AMI®
BIOS BIOS flash chip stores the system parameters, types of disk drives, video
displays, 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
<D
ELETE> 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 <D
ELETE> 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.
Caution: To prevent possible boot failure, do not shut down or reset the system while
updating the BIOS.
