[Coco] Drivewire question

[Aaron Wolfe]

The protocol uses a full byte to designate the drive number.  AFAIK the
device descriptors in OS9 also store a full byte for this.  I believe the
stock 2 or 4 is just an arbitrary limit.  The practical limit depends on
system ram, in general I'd think more than a handful is probably not worth
it.  Honestly I never use more than 2, my main OS9 partition in /x0 and
then /x1 for mounting things I need to copy to/from.



So... You *could* have /x255 theoretically, I think, but not 0 through
255.  And that's probably OK.

 Subject to finding drivewires limitation, either by Aaron piping up, or
experimentally by our own testing, I would say only that there should be
at least 7 or 8 as a limit, 8th = /x7, but thats too many descriptors
for the available sysram.  In my build here, x3.dd is the highest, so
that limit looks like 4.  That would seem to indicate only 2 bits are
being used as the drive selection in drivewire.  Aaron?
