If You Cannot Access Setup
If the diskette drive is misconfigured so that you cannot access it to run a
utility from a diskette, you may need to clear CMOS memory. You will
need to open the system, change a jumper setting, use Setup to check and
set diskette drive options, and change the jumper back. For a step-by-step
procedure, see "CMOS Jumper" in Chapter 4.
How to Enter and Start Setup
You can enter and start Setup under several conditions:
•
When you turn on the system, after POST completes the memory test
•
When you reboot the system by pressing <Ctrl+Alt+Del> while at the
DOS operating system prompt
•
When you have moved the CMOS jumper on the motherboard to the
"Clear CMOS" position (enabled); for the procedure, see Chapter 4,
under the heading "CMOS Jumper"
In the three conditions listed above, after rebooting, you will see this
prompt:
Press <F2> to enter SETUP
If the <F2> prompt does not appear
If the <F2> prompt does not appear, the display of the
prompt has been disabled in the SCU. You can enter Setup
anyway by pressing <F2> right after the system memory
size is shown.
For the procedure to enable the prompt, see "Press <F2>
Key to Enter Setup: Prompt Does Not Display" on page 50.
In a fourth condition, when CMOS/NVRAM has been corrupted, you will
see other prompts but not the <F2> prompt:
•
Warning:
•
Warning:
In this condition, the BIOS will load default values for CMOS and attempt
to boot.
