If it will help, I have DOS 5.0 I can send you. PM if interested.
I have a photographic memory, only problem is, I ran out of film.

I also have all the sets of files for DOS, from version 3.1 up to 6.22.
Have taken all the files off the floppies, archived them.
Also have an ancient set of files for Windows 2!
Remember when Win 95 was on 14 floppy disks? PDT_Armataz_01_09
Sadly, floppy disks do not store well for a long time.
Amazing that the older DOS versions needed only about 2 megs of drive space.. and now an OS needs almost 3 gigs!!!

Thanks for all the great ideas! I have been busy with a ton of other projects so this old 486 is on the back burner for now! I will try them and see what happens!

And I thought trying to get my BX box to run Vista was extreme. Did you run fdisk when booted to floppy? HDD could have been formatted with something not recognized. Must you run MS rather than PC-DOS? Must it be a dedicated machine or could it be virtual?

Most programming for older DOS setups was not specific to an MS-DOS version. There was IBM DOS, but was specific to the system design.. early versions being either CP/M or a Pascal version. IBM later updated the DOS basics, using the PC-DOS adaptation. In the early 1980s, IBM ceded to the MS-DOS version. Bill Gates (yes, THE Bill Gates) once worked for IBM. But when he suggested a newer DOS version for IBM, he was canned.
There also was a DR DOS version. MS-DOS version 5.0 was a great improvement over previous versions, as it was very easy to set system boot commands. And take advantage of extended or expanded memory on the system.
You could cull all the basic OS commands from a Win 95B version, and create a true DOS environment even on a 286 system.
