What do you mean by MS-DOS compatible (specifically)?
Think about it.

care to share an example? Well, true, but you're indulging in some
sophistry
there. For one, the
ACT Apricots didn't run /the IBM version/ of MS-DOS
- they had their
own special edition, AFAIK. For a second, they did I
believe have a
BIOS, again, their own one, not an IBM or compatible
BIOS.
Remember, I didn't originally state "IBM compatible"
bios, but rather IBM style BIOS. In essence I guess
they could be thought of as saying the same thing - if
a program accesses hardware through a particular call
present in the 5150's bios, and it doesn't crash, it
could be said that the computer has an IBM compatible
bios. The Tandy 2000s bios is largely "IBM compatible"
in that sense, but the hardware varies significantly
from a 5150.
If the question were rephrased more specifically and
precisely: can
one run the PC edition of MS-DOS on a machine with
no BIOS at all or
with a non-PC-compatible BIOS?
The question comes down to this: does DOS in a more
or less stock configuration (whatever that entails)
calls the hardware through BIOS calls (loading a
register, generating and INT ?). How hacked up dos DOS
have to be in order to run on a puter w/no BIOS at all
(and I have to wonder if there are such machines. I
could stand to learn something, but I'm skeptical at
this point).
