This is a (meanwhile) *rare* version of MS-DOS 3.31 for a Compaq PC, ca 1988.
The disk images was made with WinImage but not compressed, so it's possible
to write the .IMA files also with RAWRITE or similar.
It's the german language version, but KEYB can serve for other languages as
well, so just modify KEYB GR to whatever language or just delete the line
in AUTOEXEC.BAT .

Btw. it was the first MS-DOS version for larger harddisks than 32MB, much
earlier than a publication from Microsoft or IBM (that was done with DOS 4.0).
