21.1.4 ATA Device Paths
The table below shows an example device path for a ATA host controller that supports a single SCSI channel and is located at PCI device number 0x07 and PCI function 0x00 The PCI SCSI host controller is directly attached to a PCI root bridge.
This sample device path consists of an ACPI device path node, a PCI device path node, and a device path end structure. The _HID and _UID must match the ACPI table description of the PCI root bridge. The following is the shorthand notation for this device path:
