82 Maintaining and Troubleshooting the Gateway ALR 9200 Server
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
C
TRL
+A
LT
+D
EL
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
F
2
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.
