This looks promising. It's too bad that not even the Intel documentation
fully advertises all the tricks you can do with 386+ processors,
although it does hint at such things.

Hopefully the BIOS will not mess up the situation somehow. It would be a
fantastic breakthrough to achieve hardware independence for ColorForth.

I suspect that things are not quite so simple and that unattractive
compromises will be necessary, but it seems worth experimenting along
these lines.
