Are there any handhelds that can be changed to DOS?

Just a random thought. I was thinking about some handhelds that can be changed to Linux.
I'd guess that the processors wouldn't support it, but it'd be neat if it was possible.

Which CPU architecture are they? If they're x86 - they could theoretically use FreeDOS

This Reddit thread had some more info

Did you check out the forum section "H/PC Linux / Unix" ?

Hey, I'm sorry, I had a brain-mess-up moment, I guess I thought Handhelds as in not necessarily Handheld PCs that usually run Windows CE.

Otherwise, you could use Neko Project II to run PC-98

Or PocketDOS

But I don't know of any native operating system akin to Linux/Unix that's actually DOS. I don't think that's possible unless you just run it as an emulated program
