For its entire life (or at least since 1.5h came out) my pc532
has reported a scsi error on the first access to each of my disk
drives.  Since subsequent accesses are error free, I have just
ignored this problem until now.  With the arrival of my scsi
floppy drive, however, it appears I need to find a solution.
The floppy drive does not recover but gives an endless stream
of error messages, sense key = 5, code = 24, which translates
into "Illegal field in command descriptor block".  This is the
same error that I get (once) from my two hard drives.  Since this
appears to be a general problem of initialization I am hoping
that someone else have run into this and perhaps even solved it.

For the record, the commands I use to initialize the floppy
drive are

	mode select (0x15)
	format unit (0x04)
	rezero unit (0x01)

and I have run the exact same commands from the ROM monitor
of my ICM3216 without any problems.

For the hard disks I use the standard initialization commands
in scsi_hi.c.
