Jumpers
7.7.1 JP1 - Board Configuration Jumpers (Internal)
Jumpering pins 1-2 enable you to reset the BIOS CMOS settings to factory
defaults. The BIOS reads this pin during system boot and forces the
settings to reset if the pin is at ground.
To reset the BIOS CMOS parameters:
1. Remove power from the PPC12-427.
2. Place a jumper across 1-2.
3. Apply power to the computer, and let it boot into the BIOS.
4. Power off the PPC12-427, and remove the jumper at 1-2.
Jumpering pins 3-4 configures LVDS output as 24-bit. Removing the
jumper configures the output as 18-bit.
