BIOS Utility
BIOS Utility 2-1
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.
