Running a checked build of Windows is needed for understanding its various BIOS related BSODs. Win7 checked build complains when running coreboot+seabios:

 FADT revision inconsistent with length.
     Revision:        0x1
     Length:          0xf4
     Expected Length: 0x74

Change the FADT revision from 1 to 3 to match its length and prevent the Windows checked build assert.
