Using the BIOS Setup Program
Using the BIOS Setup Program
This chapter explains how to use the BIOS Setup program. You can use the Setup program to
change the computer’s configuration information and boot-up sequence, etc.
Your system uses a Phoenix BIOS, which is stored in flash memory on the motherboard. This
enables you to run the program at any time when you turn on or reset your computer.
The configuration you define through the Setup program is stored in a special area of memory
called C OS RA . The battery on the motherboard backs up this memory, so the memory is not
erased when you turn off or reset the computer. Whenever you reboot the computer, it checks the
settings, and if it discovers a difference between the information in the C OS RA and its actual
hardware configuration, it prompts you to run the Setup program.
