IMO POST_DIE should not be 0xff to reduce confusion. That code, in
most other BIOS vendors, is emitted when all is well and OS has begun
booting. I am proposing reserving the range 0xE0-0xEF for
unrecoverable errors. We already have POST_DEAD_CODE being 0xEE. Going
along this line we should make POST_DIE 0xEF, possibly alternating
with another code if more detail is to be provided.

What do you think?
