Chapter 2 BIOS Setup
• Because BIOS ashing is potentially risky, if you do not encounter problems using the current
version of BIOS, it is recommended that you not ash the BIOS. To ash the BIOS, do it with
caution. Inadequate BIOS ashing may result in system malfunction.
•It is recommended that you not alter the default settings (unless you need to) to prevent system
instability or other unexpected results. Inadequately altering the settings may result in system's
failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
(Refer to the "Load Optimized Defaults" section in this chapter or introductions of the battery/
clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)

The Functions of the <F11> and <F12> keys (For the Main Menu Only)

F11: Save CMOS to BIOS
This function allows you to save the current BIOS settings to a prole. You can create up to 8 proles
(Prole 1-8) and name each prole. First enter the prole name (to erase the default prole name, use
the SPACE key) and then press <Enter> to complete.
F12: Load CMOS from BIOS
If your system becomes unstable and you have loaded the BIOS default settings, you can use this
function to load the BIOS settings from a prole created before, without the hassles of reconguring the
BIOS settings. First select the prole you wish to load, then press <Enter> to complete.
