    I've been using OS2/2.0 for a month or so, on a '386DX with two
hard drives, and get the impression that OS2 does nothing else --
i.e., suspends multitasking -- while a hard disk operation is in
progress.  If true, the reason may be that OS2 must poll the hard
drive adapter to detect completion.  One piece of evidence for this
conclusion (among others) is that a simple disk-to-disk copy operation
in one partition disrupts a 9600-baud com transfer controlled by
another.
    The hard disk adapter on my machine is SCSI.  It contains posts
for a jumper, presently missing, to enable interrupts for operation
complete.  Can anyone say whether or not OS2/2.0 is capable of using
the hard disk interrupt?  Is there a mode whereby the OS allows non-
disk activities to proceed while disk-I/O is outstanding and depends
upon the interrupt to recover the disk-bound thread?  If so the
benefits are obvious and I'd like to take advantage of them.
