Yes indeed - in fact, have used it many times...  It's new with DOS 5.0,
but you can use it on any disk (assuming you booted 5.0 from a floppy)
with any DOS version on it.

Why do I use it? - Instant erradication of BSI viruses!  It's been quite
a handy tool for me - re-writing a clean Master Boot Record on an
infected hard disk.  Of course, you have to be booting from a clean
(preferably write protected - helps prevent accidents) floppy - also do
a hard-boot, as you are then *SURE* that memory is virus free when you
boot.
