Overview
The BIOS records basic system operating parameters, such as the amount of memory, the
boot sequence, and the type of video display. The operating parameters are set in the BIOS
before shipment.
The BIOS is stored in flash erasable-programmable memory (EPROM) on the system board,
and reads the system parameters in the system’s complementary metal-oxide semiconductor
(CMOS) random-access memory (RAM). When you power off the system, a lithium battery
provides power to CMOS RAM to retain the operating parameters. Each time you power on
the system, the BIOS uses stored parameters to configure the system.
The AMIBIOS Setup program, which is also stored in the flash EPROM on the system
board, allows you to manually change the system operating parameters. The Flash
Programming Utility (FPU or FLASHPROG) allows you to update the BIOS.
The AMIBIOS Setup menus and options discussed in this chapter are for BIOS 841xx.
ROM, where xx is the version. The BIOS version number displays as the system starts. The
message is similar to the following:
AMIBIOS (C) 1997 American Megatrends Inc.,
(C) 1997 Intergraph Corporation (841xx)
For a summary list of all the parameters and their settings, refer to the section “Summary of
Default and Fail-Safe Settings” at the end of this chapter.
