I'm just now searching for more, non-IBM, display drivers for the ATI Mach4
Rage Pro Turbo onboard video but I feel I might be missing something more

Hi,

Are you sure you have the right display driver installed, I have the exact
model of Aptiva as you have described and  my display is a "SIS540 display
driver", go to the following web address for more about this:
