Yes, you must keep a boot disk in the A: drive.  If you boot off a hard
drive that's not a problem.  Another alternative I've used is to install
a RAM disk, SYSGEN the RAM disk and then overlay the BIOS so the RAM disk
becomes drive A:.  You should also extend the device select jumpers
of the floppy drive out to the back so you can change it from A to C,
or just hang a third floppy drive on your system.

PIP is not smart enough to allow swapping diskettes.  Use SWEEP or
NSWEEP instead.

Sorry, can't help here.  I'd love a S-100 hard disk controller myself.
