You can enable or disable the on-board VGA by setting J8.
* default
J9 provides a way to clear the CMOS setting which may be useful
whenever the current setting is causing trouble. An example is
when you forget the password. By clearing the CMOS data, the
system can be entered and re-established again.

*Normal Operation
Be very careful that, in all cases, J9 should
remain in the Normal Operation position to avoid
the battery current linkage.
Should you set J9 to clear CMOS, you need to
put J9 back to Normal Operation before the next
system boot-up.
