Configuration Data
AT-Compatible systems, also called ISA (Industry Standard Architecture), must have a place to
store system information when the computer is turned off. The original IBM AT had 64 bytes of
nonvolatile memory storage in CMOS RAM. All AT-Compatible systems have at least 64 bytes of
CMOS RAM, which is usually part of the Real Time Clock. Many systems have 128 bytes of
CMOS RAM.
How Data Is Configured
AMIBIOS provides a Setup utility in ROM that is accessed by pressing <Del> at the appropriate
time during system boot. Setup configures data in CMOS RAM.
The AMIBIOS Setup utility included in the AMIBIOS for the Intel Triton II ISA Chipset can also
be executed via a hot key.
