- Since PC monitors are not mac monitors they need a special plist file to support them. Without this the resolution and refresh rates are fixed.
- Monitor configuration files are in /System/Library/Display/Overides
- The display file your using is probably in a folder in that directory (check the date) (DisplayConfigX will tell you)
- The program called DisplayConfigX can create a custom display file for any monitor. It adds new refresh rates and resolutions. http://www.3dexpress.de
- To get an ATI AGP card to be listed as AGP not PCI you need to install this: AppleI386.kext. See post 6 in this thread.
- I was not able to get AppleI386GenericPlatform.kext to load until I increased the version numbers of the Info.plists file. It then would load via kextload but it will not load at boot time. (Can someone figure this out?)
- When using the AppleI386.kext extension, the 8500 accelerator tried to load but locked up. It almost seems like the computer is working fine but the screen is just not visible. Like the display settings are way off!
- This lock up looks very simular to having a messed up display config file which leads me to wonder that the reason why the accelerator is not launching is due to a display file bug, display timing, sync.... Perhaps DisplayConfigX is not writing the correct data or there are some sync values that work better.(Note I didn't buy it so high resolutions were not available.)
Results: The ATI drivers wo/acceleration is faster than the vesa drivers but I can't kick the resolution up (May have to buy DisplayConfigX). I was able to make the refresh rate much higher. Don't think people need to modify there bios for this...
I urge people to investigate DisplayConfigX and AppleI386.kext + AppleI386GenericPlatform.kext.
PS: using 8F1111a
Hope this helps...
