Thanks for the runthrough. I will redo with V2 coreboot and looks like I
will have to port in some low-level VGA startup according to your patches.
I will keep the list posted with my results and problems, my goal here is to
boot Windows 2000/XP/CE on the AMD Geode LX800.

Windows support is still a WIP. I have booted WinXP with corebootv2 and
seabios on one of my boards - so it is possible. (BTW, you are probably
better off trying corebootv2 + seabios.) However, it will require some
tweaking. I posted the tweaks I used at:
Unfortunately, your board will require slightly different tweaks.
Because you're seeing a vga rom checksum issue, I'm guessing you are not
seeing any vga output from seabios. Is this correct? If you don't have vga
output you'll need to fix that first. In the above patch, you'll see that I
tweaked how coreboot initializes vga (I have coreboot copy the vga rom, but
not call it).
Where did you obtain coreboot and seabios from? (Was it from svn/git or one
of the released packages?)
