When booting in graphical mode, acpidump gives me
BGRT @ 0x000000013BC90000
0000: 42 47 52 54 38 00 00 00 01 70 49 4E 54 45 4C 20 BGRT8....pINTEL
0010: 45 44 4B 32 20 20 20 20 02 00 00 00 20 20 20 20 EDK2 ....
0020: 13 00 00 01 01 00 01 00 00 30 FF FF 00 00 00 00 .........0......
0030: 2F 01 00 00 0F 01 00 00 /.......
which looks close enough to me (I haven't attempted to decode the

Thanks!
