Great!

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?)
