Versions of EMM386

EMM386 was a MS/PC DOS utility for loading TSRs into high memory. QEMM, UMBPCI and others were arguably more efficient, but EMM386 was broadly compatible and always there.

I always wanted to know the specific EMM386 versions shipped with systems. Partly out of curiosity, but also so I wouldn’t inadertedly load an older version when they were available from DOS and Windows.

I couldn’t find it directly on the Microsoft Knowledge Base site, but this mirror lists all the different versions. I’ve refactored it into an HTML table for your delight, amusement and convenience:

Product EMM386.EXE Version
Windows for Workgroups 3.1 4.44
MS-DOS 6.0 4.45
MS-DOS 6.2 and 6.21 4.48
Windows for Workgroups 3.11 4.48
MS-DOS 6.22 4.49
Windows 95 4.95

What’s missing from this table is MS/PC DOS 5, PC DOS 2000, and Windows 3.0. Perhaps if I find them I’ll go back and add them in here.

Our last family DOS machine was upgraded to MS-DOS 6.2 and Windows 3.1. For my current nostalgia project I’m sticking with our original 6.2 disks, but I’m cheating a little and using 3.11 for Workgroups for the networking, 32bit disk access, and (cough!) stability.
