BIOS recovery mode

If you are trying to update the BIOS and have a problem such as a power
outage, the update may not be successful. You can then try to recover the
BIOS by setting the Boot Option jumper.
When you are trying to recover the BIOS, no image appears on your monitor.
To recover the BIOS:
1
Turn off the system and disconnect the power cord, modem cord (if
installed), and all external peripheral devices.
2
Remove the left side cover panel. (See "Removing the side panels" on
page 18 and "Preventing static electricity discharge" on page 15.)
3
Remove the jumper from pins 9-10 of jumper J9F2 (see "System board"
on page 6 for location) and place it on pins 10-11.
