If you are willing to port the VM86() code from NetBSD to FreeBSD and write BIOS based disk driver, you'd be a hero. Of course, this is difficult enough that the only OS out there that can do this at all right now is OS/2, so unless you are comparing the SNAP to the commercial release of OS/2, your complaint is not a valid one. It's like complaining because your car can't fly, and then arguing that this must be because it's a Ford instead of a Chevy... when in fact, checy doesn't manufacture flying cars either. > Anyway, I did fdisk, added the translated geometry and > was able to complete the installation from the boot > and cpio floppies onto the first drive.

If this is it, moving the partition up a cylinder will probably avoid the bad spot (it would have to be under the boot track or the disklabel). You may want to install a teeny DOS partition before installing the BSD -- some people have found this necessary with the new slice code in the most recent snaps.
