Chapter 3: Configuring the System
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
Chapter 5, under the heading, “CMOS Jumper.”
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 system board
to the “Clear CMOS” position (enabled); for the procedure, see
Chapter 5, 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 Chapter 7 under the heading,
“Press <F2> Key to Enter Setup: Prompt Does Not Display.”
In a fourth condition, when CMOS/NVRAM has been corrupted, you will see
other prompts but not
the <F2> prompt:
❏
Warning: cmos checksum invalid
❏
Warning: cmos time and date not set
In this condition, the BIOS will load default values for CMOS and attempt to
boot.
