PPS: I do not suggest specific UEFI-BIOS-CSM projects. Anybody?
I went searching for some recently, and the only ones I found were
pcem (no longer maintained it seems, although there was an update a
few months ago, just no new release), and of course, the original pcXT
rom from IBM which is also linked to from the pcem project.
Perhaps someone could take the xt code (that is indeed in the public
domain), and update it for working with newer machines. I
(unfortunately) am not very good with pc assembly, otherwise, I'd take a
crack at it myself.
On the other hand, there's probably someone somewhere that has done at
least part of the work, though I didn't do any searches to confirm.
I know there's the pocket 386 laptop, but I'd honestly love to see a dos
capable SBC similar to the raspberry pie that could run dos natively.
Parallax has a propeller board that does run cp/m, but it doesn't have
any interrupts, so I don't know if it's even possible to port dos to run
on it.
The arduino boards won't have enough memory, even if they could run dos,
so I guess we're stuck waiting for someone to release something a bit
more compatible.
I did lobby for parallax to put the rom at the top of their memory,
instead of in the middle, on their propeller 2 boards, so porting dos to
it might be (slightly) easier, but they went with the original design,
having the rom placed somewhere after the first 64K or something like
that, (can't remember the details). But, again, no interrupts, so not
sure how difficult it would be to port to run dos apps.
But, I guess if Microsoft can port windows to run on ARM, then there's
probably a way to run dos on a propeller 2 board, I just haven't a clue how.
But if anyone knows of a Raspberry pie type board that would run dos,
please let me know, I could sure use one.
