In pciconf output you can see > "class=0x010601". Your ICH9 controller has PCI subclass 0x06 (SATA) > and PCI programming interface 0x01 (AHCI). Thank you both! I figured it was operating normally (I've noticed no performance problems or oddities from the controller or devices attached to it). I guess in trying to find out what was going on, I saw this comment: /* is this PCI device flagged as an AHCI compliant chip ? */ if (pci_read_config(dev, PCIR_PROGIF, 1) != PCIP_STORAGE_SATA_AHCI_1_0) Which if I read the comment literally makes me believe if that does not return non-zero/NULL, that my controller is not AHCI compliant. But if it's falling back on a perfectly working generic AHCI implementation, what it reports at boot time is moot. :) Thanks again guys! Josh
