BorisBadenov X1600/X1800 Full Support Solution
GUIDE VERSION: 0.3
Credit goes out to borisbadenov for getting the official Apple drivers to work with X1600 and X1800 cards.
For the latest info and discussion about this method, refer to the 'boris thread' here
Remember the golden rule: Your Mileage May Vary. User experience has shown:
- X1600 and X1800 cards have been known to work
- 10.4.4 and 10.4.6 can give artefacts - if you get these, try 10.4.5 (eg Myzar disc)
- DVI support varies. Some can only use VGA (analogue) signal.
- The 'perfect' card for 10.4.6 is the ASUS X1600XT Silent - Sleep, DVI etc working
- Some support of dual displays may be possible. However it is not possible right now.
- Cards on motherboards supporting SLI modes (ie two cards in parallel) may have issues with this solution.
Also note you need a 10.4.4, 10.4.5 or 10.4.6 installation, and an ATI X1600 or X1800-based card.
How to Apply the Patch:
1) (Optional) Remove all GeForce and ATIRadeon kexts from /System/Library/Extensions EXCEPT:
2) Open a terminal and type:
CODEsudo -s (and enter your password)
Find where it says:
and modify it to read:
Now find where it says:
and modify it to read:
Press and hold Ctrl key and press X then C to exit. Press 'y' to save the file before you exit.
3) Go to the Apple menu, select 'About this Mac' and click 'More Information' to bring up System Profiler. You need to locate the display adapter (graphics card) and find the Vendor ID and Product ID. Make a note of these.
4) Now go back to your Terminal session and type:
Find the line containing 'IOPCIMatch' (ctrl-S to search in emacs). The next line needs to be modified to contain your Vendor and Product IDs. Take the vendor id and product ids and combine them. For example, lets say the vendor ID is 1002, and your device ID is 71c2. You combine them to a string 0x71c21002 (the 0x just means its a hex value).
The line immediately after the one containing IOPCIMatch should contain your newly-created string. For example:
Ctrl-X-C to exit, pressing 'y' to save the file.
You should be able to find two lines which look something like this:
You need to modify these to match your Product and Vendor IDs. NOTE that the string is constructed the 'other way round' this time - ie its vendor first then product. (ie 100271c2, not 71c21002).
When you have modified the file accordingly, Ctrl-X-C, then y to save.
5) Now time to clean up and get ready to boot.

6) Reboot and cross your fingers / toes / hair / teeth. When it boots again, you should have the ability to change the screen resolution in System Preferences->Display. You should also have full Core Image, Quartz Extreme and OpenGL acceleration, and no mouse tearing artefacts.
* You may have to try each output of your card, or try thru a DVI-VGA adapter to get a display.
* You may experience artefacts or other corruption. 10.4.5 seems to work best.
* If you have an X1800 card, the 10.4.5 kexts/frameworks seem to be the only working versions.
* System Sleep may or may not work. If you get it to work fully, post your findings in the boris thread.
* To speed up boot times, remove AppleHWSensor.kext from your extensions folder.
