Hi Guy's if thet don't work try this recommended by IBM
BIOS Setup
Most systems have the setup program built right in to the ROM BIOS software. These built-in setup programs are activated by a key sequence usually entered during the POST. Most systems show a prompt on the screen during the POST indicating which key to press to enter the BIOS Setup.
The major vendors have standardized on the following keystrokes to enter the BIOS Setup:
- For AMI BIOS, press Del during POST.
- For Phoenix BIOS, press F2 during POST.
- For Award BIOS, press Del or Ctrl+Alt+Esc during POST.
- For Microid Research BIOS, press Esc during POST.
