Setting the system board jumpers
The J6C1 configuration jumper on the system board lets you clear passwords and recover the BIOS. (See the figure on page 7 for the location of the jumper.) The table below shows the settings required to perform those tasks. Make sure you turn off the computer and unplug the power cord before moving the jumper.
Caution Moving the jumper while the computer power is on can damage your computer. Always turn off the computer and unplug the power cord from the computer before changing the jumper.

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 attempt to recover the BIOS by setting the J6C1 jumper.
When you are attempting to recover the BIOS, no image appears on your monitor.
