The following was designed to provide you with basic assistance only in handling motherboard Bios related issues. For more detailed instructions, see either our Award or AMI Bios pages.

You should only enter the BIOS during the boot process of the computer and never from within an operating system (i.e. Windows). On some computers you can still enter the BIOS from a DOS prompt.

There are several  ways can be used to enter the BIOS/CMOS, and the video monitor will usually indicate the method or key to use (but not always) at the bottom of the screen just as the computer is turned on.

To enter the BIOS during boot up hold down or tap one of the following keys:

  • Hold down the <Del> key (AMI and Award)
  • Hold down the <F1> key
  • Hold down the <F10> key

To enter the BIOS from a DOS prompt...( ...NOT from inside windows)

  • <Alt><Cntrl><Esc>
  • <Alt><Cntrl><Enter>
