SYSTEM BIOS AND SETUP
The basic input-output system (BIOS) is permanently encoded in
an area of read-only memory (ROM). It can be modified or
upgraded if necessary, but this is recommended to be undertaken by
an authorised engineer. It requires specialist software.
BIOS Setup is a utility within the computer BIOS. Its main
purpose is to allow you to view and alter the computer hardware
configuration. It is also used to configure various security and
power-saving options.
The current configuration is kept in a special area of memory, called
CMOS memory, and maintained by a small battery, so the
configuration is preserved while the computer is switched off, along
with other settings like the date and time.
Caution

appears at the top right hand side of the screen:
While this symbol is displayed and the memory is counting, you can

the setup utility at this time and by this method. It will take a few
seconds for the utility to load.
