Unfortunately, there is no way to suppress this message, as it is generated
deep within IBMBIO.COM's disk device driver (and no, it is not due to a 
braindamaged version, *all* versions of PCDOS--and most of MSDOS [Eagle's
MSDOS 1.25 didn't have it, but also assumed two floppies]--act this way).  I
would have suggested using INT 13h, but you indicated that it does not work
reliably on AT's.  The problem may be with having a 1.2M floppy drive...
