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 might need to clear CMOS memory. You must 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 Clear Jumper” on page 74.

Starting 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 system board to the “Clear CMOS” position (enabled); for a step-by-step procedure, see “CMOS Clear Jumper” on page 74.

In the three conditions listed above, after rebooting, the system displays this prompt:

Press <F2> to enter SETUP

In a fourth condition, when CMOS/NVRAM has been corrupted, the system displays other prompts but not the F2 prompt:

Warning: cmos checksum invalid

Warning: cmos time and date not set

In this condition, the BIOS loads default values for CMOS and attempts to boot.
