Or you know, just install it. Run plenty of MS/DOS programs all at once .

Interesting. Where have you found these technical informations? I would like to read them, in-depth.

Well, the explanation on Gunkies was basically written by Neozeed:

There’s been a lot of conversation about this release by people who hang out here since it’s such an oddball. Is there anything specific you want to know about it?

What seemed most odd to me is that Windows/386 is basically a hypervisor underneath a regular Windows/286. Win386.exe sets up EMS emulation and provides services for VM86 boxen, then launches Win86.com, a regular Windows. So a copy of Windows/386 can be run in fully real mode by running Win86.com directly, or under its bundled hypervisor. But what’s even crazier is the hypervisor can be put under Windows/286, or even under command.com, to achieve EMM386-like behavior, before EMM386 existed. I think doing this under Windows/286 won’t support VM86 boxes, but it will use emulated EMS.

“The one thing I wonder about sometimes if there was some kind of secret Microsoft extended DOS/Windows that relied on OMF & Link386”
I seem to recall that when Cutler and his people started working in OS2/NT-Windows NT they compiled and run an emulator of an Intel i860 in some kind of OS/2, like taking the early OS/2 2.00 source code and compiling with their tools.
Microsoft still had access to OS/2 source code like IBM had access to Windows code.
You could see at “OS/2 Museum” that versions of OS/2 2.00 before release used another executable format.
I should look where I read this, but it’s not easy to find.
