Only as plain IDE. You have to restrict the number of heads to 16 and
the number of sectors per track to 63 (as you did), and the root
partition (where the /kernel is loaded from) must below the 1024-
cylinder watermark. For the recommended root size of ~ 20 MB, this
usually ain't a problem. (For a non-boot disk, you don't run into
special problems.)

sysinstall uses its own libdisk. Jordan's goal is it to have
sysinstall doing all this stuff also in a running system. I'm always
using the following for a dedicated disk (i.e., one that will never
see anything else than FreeBSD):
o ignore fdisk
o create a disktab entry, starting at block 0.
o disklabel -B -r -w [sw]d[0-9]
o newfs everything
This will put the FreeBSD disklabel and bootstrap right at the
beginning of the disk, hence you don't have to muck with the geometry.

foodisk|The very Foo disk:\
:ty=winchester:dt=IDE:su#2503872:\
:nc#2484:nt#16:ns#63:\
:oc#0:pc#2503872:\
:oe#0:pe#2503872:te=4.2BSD:be#8192:fe#1024:
For an entry covering the entire disk and establishing a single
partition `e'. The nc, nt, ns figures might even be optional, given
that su ist there.
