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

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 and then press <Enter> to complete.
2-2 The Main Menu
Once you enter the BIOS Setup program, the Main Menu (as shown below) appears on the screen. Use arrow
keys to move among the items and press <Enter> to accept or enter a sub-menu.
