Features LPC connector(s) ☺
——— 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.
