  • OEMs here, nothing else.

    That's because there wasn't a retail MS-DOS until version 5. There were Microsoft boxed versions of 3.3 and 4.0, but even those says that it's for distribution with a new PC.

  • While it was for OEMs, the MS duplicated sets were easy to get. That was about the only way to acquire an upgrade. Fortunately, grey market OEM surplus boxes were quite cheap. Wound up having to pick up DOS 4.01 that way because my sales rep wasn't responsive.

  • Microsoft began to distribute MS-DOS with MS Genuine from version 3.20.
    Yes but they didn't be released as Retail package before version 5.0 upgrate released.

  • I recently picked up a copy of 4.01C new in the box, but of course I had to open it and image the disks and start scanning the manual.

  • Haha, anyone got this message ever? (Occurs while holding down Enter fast when the directory is listing on either 4.77 megahertz or something else).

    Maybe because these kind of systems, can't do various things simultaneously. Making the system, crash itself.
  • This doesn't happen (or very rarely) in hypervisors such as VMware.
  • Just a reminder. Do not make multiple short posts within a small amount of time. This is a forum, not Twitter. If you have something to add within an hour or so, edit your post.
  • Need Compaq DOS 3.20, Franklin MS-DOS 3.2, Grid MS-DOS 3.2, Hyundai MS-DOS 3.2, Leading Edge MS-DOS, and Packard Bell MS-DOS 3.2 on the list.

    Vetusware has Compaq DOS 3.20. Can't verify if it is genuine though.

  • Original MS Genuine DOS 3.20 is the only version is Not compatible with original IBM PC 5150 (Rev.1 BIOS 04/24/1981 and Rev.2 BIOS 10/19/1981).
    Of course, this problem was fixed on 3.21.
  • About the "Microsoft MS-DOS 3.20 [Amstrad OEM] [PC-1512] (with GEM Desktop 3.0) [Spanish] (5.25-360k)" My windows 10 detected that there's a virus in it and its called Virus:DOS/Kampana.A.
    I discovered that it was a DOS virus that destroys the boot sector after about 400 boots, but there no other information online. shouldn't it be checked?
  • Give it a try now.

    BTW, as it turns out, it is GEM 2.0 on those disks, not 3.0. But how would I know, some idiots didn't include label scans? Kind of important when dealing with third world languages.
