joe10190 Posted March 16, 2015 Author Share Posted March 16, 2015 thanks for the advice i acquired the AppleACPIPlatform kext v1.3.6 from the Dell latitude D620 download. Is this a generic driver that is compatable with any install? i followed your instructions but still getting PCI configuration End message. i am playing around with Snow Leopard and have just managed to install the O/S but would prefer to use Mountain Lion if possible as Snow Leopard is rather long in the tooth, but i stand to be corrected. Thanks again for your advice Link to comment Share on other sites More sharing options...
Administrators Hervé Posted March 17, 2015 Administrators Share Posted March 17, 2015 AppleACPIPlatform v1.3.5 and v1.3.6 come respectively from SL 10.6.7/10.6.8 and are generally mandatory for all Lion and Mountain Lion installations. Not required for Mavericks and Yosemite, the vanilla kexts do perfectly. All the Lion and/or ML installations I attempted without reverting to the SL version of this kext always ended in KP. As far as I know, the SL kext can be used in Mavericks and Yosemite but I found this was not necessary as all my systems ran fine with the vanilla kext of those OS X versions. Did you revert to the original IOPCIFamimly kext? I've never had to replace that kext in ML... Link to comment Share on other sites More sharing options...
joe10190 Posted March 23, 2015 Author Share Posted March 23, 2015 thanks for the reply. i have alsp copied both the AppleACPIPlatform kext v1.3.2 and IOPCIFamimly kext from a snow leopard install on a Gigabyte G31M ES2L to the extra/extensions folder in the USB MyHack installer and then ran the MyFix option targetting the USB installer. Same " PCI configuration end "message. I also tried running the Myhack MyFix option targetting the actual install and then cloned the drive to a laptop drive and then attempted to boot the acer with the new drive but again same message. Not much hair Left. Link to comment Share on other sites More sharing options...
