There hasn't been much discussion of running dos in a virtual machine. I
know it depends on why you want to run dos at all but a vm is an option
that avoids the bios/uefi issues and the need for extra hardware.

Well, coreboot opensource x86 firmware will help you! The default
coreboot's payload is SeaBIOS - a modern legacy-style BIOS written on
C, without any UEFI crap. In addition, thanks to opensource - you can
finally trust that your BIOS doesn't have the backdoors / holes /
broken code hastily written for a bowl of rice by the lowest bidder.
Of course, not every hardware is suitable for coreboot, so you'll have
to buy anyways. Personally, I can recommend the AMD boards without a
PSP hardware backdoor: Lenovo G505S laptop with A10-5750M, ASUS
A88XM-E desktop with A10-6700 / A10-6800K, and ASUS AM1I-A mini-ITX
micro-desktop with Athlon 5370 - which may be a close match for your
single-board-computer requirement (it has LPT, COM, etc.)
More information can be found on the Internet (i.e. the manuals on
DangerousPrototypes website), or you can just ask me.

What legacy OS Either DOS or directly on bare metal. It needs to start in 16bit
real mode though for either of these to work. UEFI I think starts in 32bit
protected mode (likely in ring3, so you never really can get hardware level
access to the computer). This is why it needs legacy BIOS support, so it starts
in 16bit real mode.

I don't know if this is any help but I am currently installing FreeDOS using
PCem, on an Atom based Stick PC.
What are you planning on using the legacy os for?

I found what seemed to be a good Intel x86 based SBC over
athttps://up-shop.org/up-squared-series.html but there was one problem. It
mentioned only a UEFI firmware. Nothing about supporting legacy BIOS. I know my
laptop can switch between UEFI and BIOS by changing the firmware settings (go
into the firmware menu by pressing F2 at bootup). But the lack of mention of
legacy BIOS support worried me. So I emailed them and asked. And unfortunately,
as I was worried, this was their answer:
"For the product now it’s all supported with UEFI BIOS. No legacy BIOS
supported."
So, I would like to run DOS on an SBC, but with a UEFI only system, that's not
possible.
