The disklabel stores its own version of the geometry, which you
can edit with the disklabel(8) command.  The geometry in the
disklabel should come [initially] from the values the drive reported,
but you can change them.

If you are not using a PC, then the ``BIOS geometry'' and all
statements about it can be safely ignored.  The BIOS geometry is
something that is necessary on the i386 during the boot process.

You can safely just edit the fields in the disklabel to match the
geometry reported by the disk in dmesg and then make some partitions
and newfs them.


have some documentation, but I can't recall right now where the more
detailed docs are.
