Chapter 4 BIOS Utility
The BIOS Utility allows you to view your system’s configuration
settings.
Most systems are already configured by the manufacturer or the
dealer. There is no need to run Setup when starting the computer
unless you get a Run Setup message.
The Setup program loads configuration values into the battery-backed
nonvolatile memory called CMOS RAM. This memory area is not
part of the system RAM.
If you repeatedly receive Run Setup messages,
the battery may be bad. In this case, the
system cannot retain configuration values in
CMOS. Ask a qualified technician for
assistance.
