Section 1
Running AMIBIOS Setup
A record of the computer's system
parameters (such as amount of memory, disk
drives, video displays, and numeric
coprocessors) is stored in CMOS
(Complementary Metal Oxide Semiconductor)
RAM.
When the computer is turned off, a back-up
battery provides power to CMOS RAM, which
retains the system parameters.
Each time the system is powered-on, it is
configured with these values, unless CMOS
RAM has been corrupted. AMIBIOS Setup
resides in the ROM BIOS (Read Only Memory
Basic Input/Output System) and is
available each time the computer is turned
on.
If, for some reason, CMOS RAM becomes
corrupted, the system is configured with
the default values stored in this ROM
file. There are two sets of BIOS values
stored in the ROM file: the BIOS Setup
default values and the Power-On default
values.
