Robin DISCLAIMER:I speak only for myself >email:whuts!2212msr 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... -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= ARPA: RALF@B.GP.CS.CMU.EDU USnail: Ralf Brown AT&T: (412) 268-3053 (school) Computer Science Department Carnegie-Mellon University DISCLAIMER?
