So I’ve always heard about the incompatibility, and I thought I’d give it a try in PCem. I know I used to run DR-DOS 5.00 and Windows 3.0 (because of the CGA driver) and it worked fine.
So just to prove it works, here I am installing Windows 3.0 on DR-DOS 5
And even better, running Word 2.0! Although I did install a whopping 4MB of ram on this virtual 286.
And to make it all the better, I changed to a 386, and re-installed Windows 3.0 and yes it runs in enhanced mode. And I can run DR-DOS in a windows.
Of course there was the AARD code, in the Windows 3.1 betas, but as far as I know that didn’t make it to release. I was able to upgrade to a virtual VGA adapter, and update to Windows 3.1 in standard mode on a 286, just fine
And DR-DOS worked through the standard mode task swapper
But Windows 3.1 in enhanced mode always locked up during setup. Maybe a PCem bug? I’m not sure. But Windows 3.0 works great.
