These issues have low impact because they require precise circumstances
to trigger one of them. The disk must be > 2 TiB in size and either:
- The primary GPT header is dammaged.
- The freebsd-boot partiton is located farther than the first 2 TiB of
the disc and one of its sectors takes place at a lba value that makes
the higher 32 bits of this very value change.
Errors and corrections folow:
- decl and incl don't affect CF, so replace with subl/addl $1
- repe uses %cx, so move size to it with movw
- moving a 64-bit value with %cx of 2 (should be 4) so addresses
> 2TB will work.
