Is the drive set up correctly in your machine's BIOS? The i386 boot
loader uses BIOS disk I/O routines to load the kernel into memory; if
the BIOS can't figure out how to talk to the disk, you're hosed.

Yes. Usually you don't need the -b and -s arguments if you've set up
your drive in /etc/disktab properly.
