Again, don’t just read this blog because you have a MacBook Pro Core Duo and you want to make it act like a FireGL V5200, read it because you care. Seriously, I got the ATI Moiblity X1600 to softmod into the FireGL Mobility V5200 following a myriad of somewhat unintelligible instructions from the internet (I think I get points for reading both Chinese and Italian posts which referenced this mod).
The driver I ended up using was from the actual AMD/ATI official site but it was an older version, 8.353.1.1000 to be exact – from 5/8/2007. There is a chance that the newer ones will work but you have to do a patch using RivaTuner 2.11 using one of the patch scripts I found and my concern was that the older scripts would somehow not work with the newer drivers. So yeah, you run the copy/pasted patch script on the driver you downloaded and you modify one of the setup files within the installation to allow the “MacBook Pro Mobility V5200″ to appear as an option and actually talk to the correct address in the system. From there you should run “Driver Sweeper”, uninstall all existing video drivers, and reboot and hopefully it goes to a safe mode VGA driver. At this point you’ll try and install the thing. It worked on my 3rd or 4th try finally using the new ATI driver, so go figure.
The good news is SolidWorks runs a whole lot better with the FireGL driver and the Instant 3D stuff works as well, Window XP’s video is a whole lot snappier. Now if only I had that older Broadcom Chipset so my signal strength in XP would come back..
