On my 7500 (which also uses /chaos/control and OF 1.0.5), the video almost
always comes up at 640x480, 120Hz.  (Sometimes it comes up at 60Hz, and
other times nothing happens at all.  I suspect OF isn't initializing
part of the hardware...)  Many monitors won't sync to this, and
it's possible that they'll hurt themselves trying.

I believe this refresh rate is available as an option under MacOS, so you
should be able do find out whether your monitor can handle it by trying it
out there.  Most modern multisync monitors will disable video instead of
eating themselves when they can't handle the signal (some will even tell
you the horizontal and/or vertical refresh rates of the signal), but
older monitors sometimes just make horrible noises and/or release
smoke.

What is the "OF 1.0.5 patch"?
