Dual BIOS support

The SBC-iTC platform supports two BIOS chips - one is installed on the core (CM-iTC) and second is installed on the base (SB-iTC) for safe backup. Jumper E11 controls which one of the two chips is used.

BIOS Source E11 Jumper Position
BIOS on SB-iTC 1-2
BIOS on CM-iTC 2-3

It is allowed to boot from one BIOS source, switch the E11 jumper position and update the other BIOS chip.
