Of course this way it works. I couldn't see how you can call BIOS from
within VDI trap. This is feasible. fine.

Oh, I see. hmm. As far the fVDI has still problems with compilation in
gcc. I would not bet in that. The bconout.prg should workaround such
situation hopefuly.

I'm looking forward the oVDI implementation as this should be the one
compilable just like the FreeMiNT kernel using gcc and
possibly crosscompiler. (Hey Odd! :))
