 Point is that minixfs update knows which drives to do. If you don't and
call Dcntl() on any drive existing, you'll end up starting the floppy each
time probably. That`s where I ended up when making an external `sync'
program for minixfs, and will probably disturb you, as it disturbed me,
I can tell you...

 So you might consider an option to map out some drives which are likely
not to be minix ones. Or something like this.

 Better: Make minixfs use the cache mode in a `per drive' way and assume
that floppies won't use the TURBO mode. You might think of other reasons
why this might be a good idea... Stephen??????? :-)

so long,
