Hi,
Thank you for your answer
CPU : Intel Core I7 2630QM
The bootloader is chimera (chameleon, stolen and rebranded). 4.1.0
With -f -v and the system is booting. I reloaded all extensions including dsdt and the bootloader, I updated the video card driver. Now everything works.
SD reader can not find the kext for it to work, you know if exist?
Thank you.
