That's because the drive is presented by the BIOS as a floppy drive.

That won't help either; it will try to use BIOS unit 0x80, where the 
IDE zip is 0x0.  You may have better luck with the new boot1/boot2 code;
I haven't got that far in testing yet.

If you're interested in working on this for the new bootstrap code, 
drop me a line and I can explain the (relatively simple) issues 
involved and get you going in the right direction.
