Hi all,
Recently I have obtained a desktop/industrial motherboard
DFI-CA331-NR (Manual),
which uses Intel GM45 and ICH9M-E as master bridges, and DDR3 ram
modules, much like lenovo x200. Other than those, it uses a Winbond
W83627UHG (which is already supported by coreboot) as superio, and
has a pci-e 1 x16 socket export from the northbridge, a pci-e 1 x4
socket export from the southbridge, as well as a Realtek NIC
attached, 2 32/33 pci socket export from the southbridge, with a
IT8213 IDE Controller attached, all of which can be seen in the
manual mentioned above, and some further reports obtained via a live
system are attached.
It has a socketed, easily removed 4MiB soic-8 spi flash chip
(originally a SST25VF032B) to store its firmware, making
brick-rescue easy, and all region is rw for CPU, making it possible
to flash it internally. I am even curious whether its ME is active,
since I can read the whole content of the flash internally with
flashrom(1).
I want to port coreboot to this motherboard, and I have read Supporting
a new board with the same cpu family, chipset but different
superIO. What further information should be gathered
before I start porting?
Best Regard.
