Which 4.01 version is this one?

Post by DoutorHouse »

I just bumped into this collection here: http://disks.oldos.net/OperatingSystems/ and was wondering which OEM MS-DOS 4.01 is that? MSDOS.SYS is from 1990 and i haven't found anything similar anywhere. SELECT.EXE is also different (and smaller) from the ones on other known english versions but installs exactly like the others. Maybe some expert here has an idea?
Thanks!

Unless you know what original media looked like or if there are any OEM-branded apps included with it, it's usually hard to tell. Especially with these later versions (4.x and later), when most hardware was PC-compatible and OEMs no longer did extensive modifications to the core OS (especially IO.SYS).

Thanks for the info! Unfortunately I couldn't find any images of those diskette images at the site... Probably it's some obscure DTK OEM! (No idea, really!) :)
