The 2220 cyl, 4 head, and 76 sector information is incorrect if you want
BSD to reside with DOS on the same hard drive.  You need to determine what
DOS is using for translated parameters, and it appears that the FreeBSD boot
disks still aren't picking up the correct information still.

Use pfdisk from the dos_tools directory to determine what the translated
parameters are and use them instead of the real geometry parameters and
it should work better.

(While you're at it, get the offsets and all the correct info from the
drive as well to make sure the install disks are doing the right thing.)
