oh, it's not that bad - learning is fun!

That would be good!  Consider this to be part of the demand!

What makes 32-bit more difficult, just that it differs from the
existing 16-bit mode, or is there some inherent problem?  Do any of
the SCSI card drivers use 32-bit mode?

Yep, I can confirm this - the Blitz is identified as an ICS IDE, so
the manufacturer and podule ids must be the same as the ARCIN V6.
However, the identification string doesn't get displayed - presumably
because it is in EASI space.

However, having run with both the Blitz and ARCIN cards installed
seems to have created a problem :(
RO still works with the ARCIN, but BSD now panics, even when there is
no drive attached (Yes, I have removed the Blitz!). Grrrrrr.
I've tried a delete-power on, checked *Status, *Unplug's etc, but I
can't see any obvious reason for the ARCIN to have stopped working.
