I got a fresh "Stock 10.5.4" install on a T61 model 7663-BR1, and installed 82566mm driver and batterymeter driver, the final thing i want to do is to enable QE/CI on the NVS140m chipset. I extract the video rom from Lenovo Bios, but it do not contain any NVCAP value in it. Somehow, there is another file named Display0.rom, can be scaned by NVCAP_Maker.app, but i got a strang value:
After trying a lot of NVCAP value, i read a thread of a user who use NV140m on DELL D830 successfully enabled QE/CI, I decide to use original kext without any injector. and then i found:
when i delete the GeforceGA.plugin, system can boot, some graphics kext can be loaded, but with no QE/CI and Resolution support. In About this Mac, it said
then i use "ioreg -l -w0" to locate the problem, several lines attract me:
personally i believed this is the problem, where the graphics card were recognise as using an AGP bus but not PCI bus. Then I try to upgrade my iopcifamily.kext from 2.4.1 to 2.4.4, but it could not help.
I will continue my research, anyone who can give me some advice?? Thank you very much.
Attach is my ioreg result
