BOOT Option jumper

The BOOT Option jumper on the system board (pins 9 through 11 of jumper J9F2) lets you recover the BIOS. (See the figure on page 13 for the location of the jumper.)

The following table shows the settings required to perform those tasks. Make sure you turn off the server and unplug the power cord before moving the jumper.

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:

1Turn off the server and disconnect the power cord, modem cord (if installed), and all external peripheral devices.

2Remove the back top panel. (See “Removing the back top panel” on page 28 and “Preventing static electricity discharge” on page 25.)

3Remove the jumper from pins 9-10 of jumper J9F2 (see “System board” on page 13 for location) and place it on pins 10-11.
