OK, I figured out what's up.  I was starting with blank, empty hard
drives, and sysinstall wasn't getting the geometry right.  I went in with
MS-DOS, fdisk and format and made partitions and formatted the first one.
Having done this, suddenly the disk geometry changed completely and I was
able to do what I wanted to do.

Interestingly...FreeBSD guessed the geometry to have something like 13,000
cylinders on a 6.4GB HD.  When I DOS-formatted the first partition, that
number dropped down to < 900.  :-)

SO:  The TP's seem to have LBA in the BIOS.  (I think that's what this
means anyway.)  Always keep your old MS-DOS floppies running around.
