2 AMIBIOS Setup
In ISA and EISA computers, the system parameters (such
as amount of memory, type of disk drives and video
displays, and many other elements) are stored in CMOS
RAM. Unlike the DRAM (dynamic random access
memory) that is used for standard system memory, CMOS
RAM requires very little power. When the computer is
turned off, a back-up battery provides power to CMOS
RAM, which retains the system parameters. Every time
the computer is powered-on, the computer is configured
with the values stored in CMOS RAM by the system
BIOS, which gains control when the computer is powered
on.
The system parameters are configured by a system BIOS
Setup utility. Historically, BIOS Setup utilities have been
character-based, required keyboard input, and have had
user interfaces that were not very intuitive.
