FB stuff from Rev 1 G3

[Joe Julicher]

Hello,

I am trying to get 1600x1200-75 running on my G3.  The fb.modes database
does not have such an entry.  The closest being 1600x1200-76, which my
monitor complains about, or 1600x1200-66 which I complain about.  The MacOS
can do 1600x1200-75 (or so my monitor tells me) and the G3 documentation
says that is the greatest that my Rev 1 machine can do.  I CAN get this
setup with the no-video driver setting at boot.  BUT of course I want the
accel video.  How do I glean the video timing for this video mode.  Is
there a MacOS utility to measure the mode?  Is there a FB method to report
the mode when using the generic FB driver?  I tried fbset while I was in
no-driver mode, but it reported strange things that made no sense.  I
haven't yet sat down with a calculator and tweaked the 76hz & 66hz settings
into a 75hz setting.  I suppose that is what I need to do.

About my G3

Thanks,
