BIOS Recovery
Onboard there is a soldered SPI bios connected to an interface of the Super I/O IT8712.
Next to the PC104 header is a connector to plug in a recovery bios on the LPC bus.
If the system should boot from a connected FWH, the pin 6 "BIOS_DISABLE#" have to push to ground.
The mounted SPI BIOS will be disabled for booting activities and can be reprogrammed with a tool running in
DOS.
To program the SPI flash the FWH can be disconnected after the operation system is loaded successfully.
