BIOS won't reset, Dell Optiplex

Postby msinger » Wed Nov 27, 2002 3:43 pm

I have 4 Dell Optiplex GX110's that won't boot. The Dell BIOS Revision A02 screen comes up, and stops. If you reboot 3 times you get the message "Alert ! Previouse attempts at booting this system have failed at checkpoint [krst]". It looks like it is trying to boot Phoenix ROM BIOS Version 1.10. I purchased these systems used, from a Dot.Com Busted Company. I believe they were running Linux and possibly booting from a server. They each had two NIC cards. There is no BIOS reset jumper on the motherboard that I can find. F2 won't bring up BIOS Setup. I have even pulled the backup battery and unplugged the system to see if that would reset the BIOS. Nothing seems to work. Any ideas would be appreciated. I am sure Dell wants alot of money for replacement motherboards.

Is your BIOS chip removable in the system?

There appear to be no removable rom chips at all.

If there is only one jumper on the entire board:

make a bootable bios flash disk.
power down
pull jumper off
insert disk
power on
wait for one beep, starts reading, two beeps, stops reading. power down. put jumper on pins 1-2
power on.

There is one removable jumper. I copied the bios executable from Dell for the Optiplex GX110 to a floppy. When I recycle the power on the Dell, it does not even appear to read the floppy drive, so nothing has changed in the boot process. It remains to stop during the boot.

Other ideas?

Thanks in advance.

Isn't that an executable that builds a bootable bios disk? Execute it, don't just copy it...

The BIOS update is designed for flashing at bootup. The PC does not appear to access the floppy drive at all. The light on the CD drive flashes briefly at bootup.

OK, This has to be the strangest thing I have ever come accross. When I plugged the Optiplex into a KVM box and powered it up, I got thru the BIOS boot process, and was able to get into BIOS Setup. I checked it out on another of the same systems with the same problem, and got the same result. I am now able to load a new O/S.

I wonder if after I load the O/S, will it boot without the KVM?

I'll let you all know.

:D :D :D
