Sorry, the off by one is my fault in rev 1.35, but it has been there
before 5.0 and fixing x86_autoconf.c doesn't make "root on cd0a" work
without this workaround at least on my Optiplex 760.

I think the problem in subr_disk_mbr.c is that it makes
/dev/cd0a unconfigured if any unexpected error occurs during
reading media because kernel recognizes boot device as cd0 properly:
