I've been annotating a listing of the MASM generated colorForth 1 that
I did form the Pentium 4. I got to the part about int 10 -- the
display set-up interrupt and had a thought.

The monitor that I had seemed to recreate Nick's display problem is
EGA/XGA. Nick, please check yours as well. In the case that it is, we
will need to enter a new display mode setter other than 0x4F02H, which
is specifically VBE, the Vesa superVGA setting setter. VESA monitors
seem to be set to 0x117h, 0x118h, and 0x123h successfully.

I don't believe anyone has tested the EGA/XGA settings.
Wikipedia has this to say: http://en.wikipedia.org/wiki/XGA

My projects are many and I keep flipping from one to the next. I do
have an XGA monitor, and if we can get some concensus on how to
preceed here, I'll try out some of those ideas.

BUT, I suggest a VESA-VBE superVGA monitor. Used, they are cheap. Bet
you can find one in a friends garage if not your own. :-)

Getting the superVGA means not having to worry about hacking the
already well tested code.

Much luck!
Ray
