Yup.  But the bus on time (per Roy's messages) is only a problem when doing
overlapped I/O with both the hard disk and the floppy -- i.e., when doing
a backup.  On the assumption that the disk transfers are faster with N:11,
I'd like to only slow things down for the duration of the backup.  Hence
my query.

Side note:  Wouldn't it be nice if there were a place to get the Adaptec
driver updates?  Northgate is still shipping ASPI4DOS v 2.0; I managed to
wangle 2.1 (a beta copy, though), and apparently (from your message), there
is a revision to the official 2.1 release.
