As Vincent said, "exactly". Therefore in the general case, it can't be used to
detect the presence of Hatari.

Unfortunately the Falcon SCSI implementation does not report errors, but does
not behave properly either. This is mostly because the SCSI chip is "behind"
the ACSI hardware registers. I have figured out a reasonable workaround, but I
hate having to do this every time I'm implementing hardware support. Thus the
request.
