Hi, mormegil. Thanks very much for your help.
Yes, it's a loptop CQ60-202TX, and running 60bit Snow Leopard, using Chemeleon 2RC3. I also have tried PCEFI 10.3 but it didn't help. I patched binary AppleHDA by replacing 6202EC10 with 5150F114(linux dump:0x14f15051). I also tried replacing others as in this thread mentioned with 5150F114, but the same result.
On leopard, I have a patched working kext(no recording) and just followed this guide to import to SL. I just learned dump from linux and use codegraph & verbit to get verbs, but don't know how to manually put layout and path map, could you tell me how to?
Thanks a lot.
