That is false. If you are in the CDROM software business, it is crazy and/or silly to ignore the installed base, which I bet is more 1542B than 1542C. For that matter, isn't the 1542CF itself obsolete? I thought Adaptec had turned away from the UNIX business with their new, super smart boards, and stopped making 1540's of any variety. Are the Bustek board that are 1542 compatible capable of switching which target is booted? You do have a point this boot switching facility of the 1542C makes the reports that 386BSD 1.0 can be booted from CDROM less ridiculous. It is of use only when you've lost the boot floppy. As I wrote before, if I were to pay $100 (instead of the going rate of $25-50) for a UNIX CDROM that costs $2 to print, I'd expect the vendor to provide miniroot boot floppies, if only to save me the time (and likely human errors) of messing with my SCSI adapter's configuration.
