The last time I used FIPS (a few months ago), it didn't do the partitioning
quite right. As I recall, it got the block size and offsets correct, but it
messed up the cylinder/head data (or maybe it was vice versa :-) ).
I eventually ended up going back with the NetBSD fdisk and putting those values
in sync. I'd recommend using that or pfdisk to correct the partition table.
(Side note - it might be a good idea to include fdisk on the install floppies;
last time I checked there was enough room.)

Again, either pfdisk or the NetBSD fdisk work great for that.

I seem to remember this error will occur, but the disklabel command actually

You'll need to fix this 'd' partition.
