Using the BIOS Configuration Manager
Setting the system board jumpers
The J1F2 configuration jumper on the system board lets you clear passwords
and recover the BIOS. (See the figure on page 6 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.
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 J1F2 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
Open the case by following the instructions on page 17. (See “Preventing
static electricity” on page 15.)
Caution
Moving the jumper while the computer’s power is on can
damage your computer. Always turn off the computer and
unplug the power cord from the computer before changing
the jumper.
