What i want to do (for now):
· Connect second main spi flash on top of existing one with help of chip
select (only one resistor has to be removed from pcb for that!)
· Connect additional Super I/O (W83627THF/W83627THG) with hefras pin
active to get configuration register on 4Eh instead of 2Eh (which is
being used by EC). No conflicts have been found (yet). PCB with Super
I/O IC will reside in place of Optical Disk Drive (RepRapped in future,
for now from scrap HDPE).
· Run SerialICE thanks to the rs232 on that additional Super I/O
· Port flashrom if using phoenix tool will be not possible.

What i want to have:
· rw access to WikiPage about JHL90

Yes, i know that porting coreboot to this board will be hard and
painful, and could be even completely unsuccessful.
