Tom, why do you always misunderstand? You really think I didn't know
this already?

DOSEMU runs on Linux natively but still needs 16-bit DOS (kernel,

Bart has (mostly) made it compile, so far.

"That" meaning DOSEMU, hence it can run atop Linux (32-bit or 64-bit).

"Prolong" as in finally be widely accepted into Linux distros without
being relegated to "contrib" or "universe" (multiverse? I forget) due
to "using non-Free build tools".

Right. I never said otherwise.

Yes, but DOSEMU fakes all of that, so there's (probably?) no real BIOS
access here.

(I guess V86 mode could maybe do it, if needed, but that's not
available under x64, more or less. There are some extremely obscure
third-party hacks, but I've never investigated. Just for completeness,
read [old] http://v86-64.sf.net if curious, but it's probably not
totally reliable. I think VT-X is probably a better path going forward
and is already partially supported under DOSEMU2.)

this is simply nonsense.
a GCC compiled FreeDOS kernel will work *exactly* where the standard
WatcomC compiled works; no more , no less (bugs aside).

the GCC kernel is still 16 bit stuff, and requires a working BIOS.
