Form factor

These boards use the SSI EEB 3.61 form factor; make sure that your case supports this. This form factor is similar to E-ATX in that the size is identical, but the position of the screws are different.

Flash chips

These boards use LPC flash (not SPI), in a PLCC socket. The default flash size 1MiB (8Mbits), and can be upgraded to 2MiB (16Mbits). SST49LF080A is the default that the board uses. SST49LF016C is an example of a 2MiB (16Mbits) chip, which might work. It is believed that 2MiB (16Mbits) is the maximum size available for the flash chip.

DO NOT hot-swap the chip with your bare hands. Use a PLCC chip extractor. These can be found online. See http://www.coreboot.org/Developer_Manual/Tools#Chip_removal_tools

Native graphics initialization

Native graphics initialization exists (XGI Z9s) for this board. Framebuffer- and text-mode both work. A serial port is also available.

Memory

DDR2 533/667 Registered ECC. 16 slots. Total capacity up to 64GiB.

Hex-core CPUs

PCB revision 1.05G is the best version of this board (the revision number will be printed on the board), because it can use dual hex-core CPUs (Opteron 2400/8400 series). Other revisions are believed to only support dual quad-core CPUs.
