The LPC port can be used to connect an additional super I/O device, or for an alternate flash
EPROM to start the board when on board flash is corrupted or blank. Unlike earlier SC1100 based
WRAP boards, this port cannot be used as GPIO pins. The on-board super I/O is configured at
I/O address 2Eh, please select a different configuration address for expansion devices...
