Hello I'm trying to mod my bios. Somebody who have something with ICH7M chipset ( 82801GBM/GHM ) working in AHCI mode can dump pci register and provide me this dump? Some notebook don't have this option in bios,so in case you don't know if is in AHCI or legacy compatible mode take a look at device id, 27c4 - legacy compatible emulated mode 27c5 - native AHCI For dumping this you can use RW-Everything or pciscope Thanks.
