Running or Accessing the CMOS Setup Program
If you want to run the BIOS Setup program, you usually have to reboot and press a par-
ticular key or key combination during the POST. Normally, the correct key to press is dis-
played onscreen momentarily during the POST. If it flashes past too quickly to read, try
pressing the Pause key on the keyboard when it appears. This key freezes the system, al-

lowing keystrokes to enter the BIOS Setup in recent systems:
• AMI BIOS —Press F1 or Del (Delete) during POST.
• Phoenix BIOS —Press F1 or F2 during POST.
• Award BIOS —Press Del (Delete or Ctrl+Alt+Esc during POST.
• Microid Research (MR) BIOS —Press Esc during POST.

when prompted.

Ctrl+Alt+Esc or Ctrl+Alt+S.
