      Ron asked:

Dave, can you check this out? Particularly raminit.inc, northbridge.c, and 
mainboard.c
mainboard.c has come errors, "dev" isn't declared in one of the functions,
nor is "i":

vgabios.c needs to have the vgarestart label defined:

So I'm not sure what the problem is...
BTW I got all kinds of warnings:

Don't know if these are related...
Hope this helps...
