VGA Mode
J25 on the system board enables or disables the VGA mode for the graphics accelerator. If the jumper
is not installed (default), the VGA mode is enabled. If the jumper is installed, the VGA mode is
disabled. You must remove the PCI option boards and the processor module (or P6 bus termination
card) to access J25.
NOTE The jumper is absent if the system board does not feature onboard G95.
BIOS Password Clear
J16 on the system board enables or disables the BIOS password stored in CMOS RAM. If the jumper
is not installed (default), the password (if present) is enabled. If the jumper is installed, the password
is cleared, allowing the AMIBIOS Setup program to be accessed without a password. You must
remove the PCI option boards and the processor module (or P6 bus termination card) to access J16.
