So that's a 1st generation iMac with an ATI Rage II on the
mainboard -
you may want to look for a VRAM module, standard video
memory is only
2MB which s rather limiting, with such a module you can have
up to 6MB
which would allow 1024x768 in 24bit.
The only real catch with X on this hardware is the monitor -
it needs a
fixed horizontal frequency of 60kHz. Just do X -configure,
this will
put a mostly working XF86Config into your home directory,
then add
'HorizSync 60' to your monitor section. With this X should
come up in
1024x768 at 75Hz. Without this line X may come up in a video
mode the
monitor can't display ( the horizontal frequency needs to be
very close
to 60Hz or it won't sync ). Unfortunately there's no way to
identify
this monitor in X since it doesn't provide any DDC data.
have fun
