Ok. Under the excellent guidance of Ron I finally got LinuxBIOS to boot
on our custom 440bx board by hardcoding the right values into the DRB
and page size registers.
The problem seems to be that linuxBIOS dosen't detect the RAM properly
in row 0. Its seems to be setting it up at row 1.
I've been trying to use dump_spd_registers to see if I can figure out
whats going on but all I seem to get is something more or less like the
following:
dimm 50
dimm 51

I've played with SMBUS_MEM_DEVICE_START but I still just get 04's.
What's the standard adress for the spd info?
If this is truly what linuxbios is getting back from the spd then I can
see why its confused.
