[Dave Ashley]

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:

When I build and attach my payload and my vgabios.bin, I get into linux
...
ip_conntrack version 2.1 (1016 buckets, 8128 max) - 292 bytes per conntrack

So I'm not sure what the problem is...
BTW I got all kinds of warnings:
/ram/freebios/src/cpu/p6/mtrr.c: In function `set_var_mtrr':

Don't know if these are related...

Hope this helps...
