I care. I want to be able to write 32-bit
applications and be able to debug them by
putting debug into the OS, not just the
application.

And if my computer hangs, I want to be able
to debug the OS.

And if I spend time debugging the OS, and
getting familiar with it, I want to be able
to create a commercial derivative of it
without restriction. And for that I need it
to be public domain.

And if I enable paging but keep V = R, to
enable memory protection, I want an MVS-style
dump produced. I already have proof of concept
for that with divide by zero.

If you don't have the same requirements,
that's fine. But don't say "nobody". I'm
not trying to win Miss America, I'm trying
to create a pristine programming environment.

Applications are normally bottlenecked in
the application, not in the OS.

I don't want to run DOOM.EXE. I want to
run GCCWIN.EXE and GCC386.EXE.

I'm a programmer, not a gamer.

Regardless, I don't know what the internals
of DOOM are, but if it just wants to take
control of the hardware, it can do that
under PDOS. It needs to be compiled to one
of the two supported formats though. If it
doesn't come with C source code you won't
be able to do that currently.

BFN. Paul.
