Does macbook's firmware allow putting the controller into > ahci mode? Do you mean, that one can configure the firmware, so that it puts the controller in ahci mode during boot? I don't know. There seems to be no user interface for the firmware. The refit bootloader is able to manipulate efi setting variables, but one would need some documentation to understand the meaning of them. Or do you mean, that one can switch to ahci mode under linux? Sincerely, Thomas Rohwer
