I have a notebook (Acer Aspire 5550) with the Intel ICH7 chipset (see attached lspci output). Unfortunately, the SATA controller is stuck in non-AHCI mode and the braindead BIOS doesn't allow me to change that. Is it possible to change the controller to AHCI mode in software, e.g. through ACPI?Unfortunately, nobody on linux-ide seemed to have an answer for this so far. Therefore, I am hoping that some of you ACPI guys can probably help me out..
