J11 / J6
The LPC port is used in the factory to connect an alternate flash BIOS to start the board when the
on-board flash is corrupted or blank. Use PC Engines adapter LPC.1A for this purpose if needed.
The LCP port can also be used to connect a super I/O device. Unlike SC1100 based WRAP boards,
this port cannot be reprogrammed as GPIO pins.
