Provided you've got out of pbr.S all the reads start as being by sector
number, but will be converted to CHS based on the geometry the bios
returns - so shouldn't be wrong.

sysctl machdep.diskinfo should report the values being used - if you have
managed to boot a kernel that knows about the disk.

Shame the error message doesn't contain the sector number.
There are some print functions available in bootxx.
