CPU: merom/penryn support (µPGA-478)
667/800/1066 MHz FSB
Intel Cantiga + ICH9M
2x DDR2 SO-DIMM
GPU on MXM-II slot (nvidia 9600M GT)
EC: ENE KB926 (datasheet under NDA, firmware description as part of 
service manual — very well documented)
———
Flash chips:
One on SMBus — contains some information which can be changed by 
retailer, re-branding is common practice
One on SPI bus connected to SB — ¿¿¿¿¿¿¿ for iTPM and HDCP in 8M (1MiB)
One on SPI bus connected to EC — Contains EC firmware, BIOS (PHOENIX) 
and VBIOS (NVIDIA) in 16M (2MiB)

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.
