FYI all x86 CPUs support the 16 bit mode. Nowadays the common way to implement it is through hardware emulation (read: it looks like normal operation but it's slower than 32 or 64 bit modes would be) by using microcode instructions. They basically have a CPU inside the CPU that executes bigger instructions as a series of smaller instructions. As such, they take several cycles to complete, but since modern CPUs are several hundred times faster than a 33 MHz machine, it shouldn't be an issue.

Isn't DOS 16 bit x86 though ?
Yes but i think a person need only buy a 16 bit processer for it to work, or just ajust the code to be 32 bit.
Judging from the terms you may not distribute ms dos nor derivative works, so if you make a gui for it it will be only for you to use.
Also right,
Judging from the terms you may not distribute ms dos nor derivative works, so if you make a gui for it it will be only for you to use.
Well, you could make it into a patch, then you are free to distribute it.
This can even be done in an installer that automatically downloads DOS and applies the patch.

Incorrect, you can not do that. Its not TI-care.org, its MS-care.org... ;)

Yep, MS-DOS 6 is still in the MSDN store.

Remember the day the walrus started to fly...

I finally cleared my sig after 4 years you're happy now?

Hmmm I don't like this bit:

This licence doesn't encourage modifying the os to suit your own needs. If I wanted to make an operating system I'd use a linux kernel instead of modding ms dos.

Indeed. It's Microsoft after all. But I don't know if they really care.

Actually, seems they're encouraging usage of the code more for educational and research purposes, as in, a CS teacher might use it to teach assembly and/or how to make a basic operating system. They might even ask their students to e.g. add a custom command into command.com as an assignment.

Microsoft actually cares a lot about education.

That is nice at least. But the rules are very restrictive for such an old piece of software few people care about.

Cough, cough, watya mean? as a potential market? that, i might just agree otherwise i'd say they couldn't care less.

well, some oldie concepts last for centuries, as you well know... so, can we make any use of it? :P

Why did you add the sunglasses ? :P
Also, that's true. But the way they put it sounds like "we released the source, you can take a look at it but if you change the smallest byte, it's ours". So there's no use for that. :/
