For maximal compatibility, I'd like the following mappings for SS-5,
SS-10, and SS-600MP:
-hda = SCSI ID 0
-hdb = SCSI ID 1
-hdc = -cdrom = SCSI ID 2
-hdd = SCSI ID 3
There is no bus 1, only 0. Maybe a warning should be issued for bus=1.
I didn't find where this was implemented, so is the above in line with
the patch?

This is broken, there are zero or one floppy drives, never more.

I think same applies here (0 to 1 drives), but as the hardware is
PC-like, technically it may be possible that someone could replace the
cables and insert additional floppy drives.
