BIOS Setup Utility
The BIOS (basic input/output system) contains important information
used to configure the hardware and system software settings. Your
computer reads the BIOS when it first starts up, before it loads the
operating system.
Your computer's BIOS includes a built-in setup utility called Insyde Soft-
ware SCU (system configuration utility). It can be started shortly after
you turn the computer on, by pressing the F2 key during POST.
The BIOS setup utility displays summary information on your computer,
its devices, processor and memory.
Your computer is already configured for optimal performance, so you
should not need to run this utility. However, you may need to change
the BIOS settings if you encounter configuration problems in the
future. Refer to “Frequently asked questions” on page 75.
