Since I don't have a 4500, I can't try this. So 0x2A428086 becomes 86 80 42 2A (do not use the 0x)ĭo the same for AppleIntelGMAX3100 file of the other kext.Īnd please post back. Replace: byte-reversed version of what you put in the plist. Then with an hex editor open the AppleIntelGMAX3100FB contained in the kext and do a Find and Replace. With one of the following (depends on which 4500 you have): Open up the ist of the AppleIntelGMAX3100FB.kext and replace the 0x2A028086 in this string: Martin (or anyone else who's game to try):ġ. I verified that the IDs are indeed in the kexts with hexedit. The target device IDs are hardcoded on the kexts you need to edit them with a hex editor It's quite possible that this won't work at all, since the kext will be doing probing for properties that are not exposed via the ist. $> kextstat | grep AppleIntelGMAX3100If it's not running, there will be no output. Check Utilities/Console and look for any text related to the GMA kexts. Verify that AppleIntelGMAX3100FB.kext/ist has:Ġx2A028086The translation is that this matches any PCI device of class code 0x03 and vendor 8086 (Intel) AND vendor Intel (8086) and device id: 0x2A02.ģ. It doesn't check device or subsystem ids.Ģ. Verify that your AppleIntelGMAX3100.kext/Contents/ist has:Ġx00008086&0x0000ffffThe translation is that this matches any PCI device of class code 0x03 (which I presume is graphics, as 0x02 is network) and vendor 8086 (Intel). So could someone try the following experiment and report back?ġ. I think it's worth trying to see if the GMAX3100 kexts in Leopard can drive the 4500 series. Intel has moved more features into the chipset (versus relying on the CPU) in the evolution from the GMA900 to the GMA4500, and they've added support for different display connections like LDVS. I've looked over Intel's docs on the 4500, and I find broad compatibility in the architectures. But maybe you can join forces with this happy person: It's not like with the X3500, which was just a variation. Uman, as far as I know the X4500 architecture is really different of the X3100 (according to Intel marketing, anyway).
