The BIOS is busted. ACPI is supposed to enumerate all the Host-PCI bridges as ACPI devices with a specified _HID or _CID of "PNP0A03" and a _BBN field to indicate the PCI bus number of the immediate child bus. Your pciconf shows 4 Host-PCI bridges, but ACPI only lists 1. I would look for a BIOS update and/or flame ASUS for violating the spec. There's no standard way to figure out what PCI bus numbers to use for the Host-PCI bridges, which is why ACPI is supposed to enumerate them with appropriate _BBN methods. Your network device is probably on one of the PCI busses we aren't seeing. -- John Baldwin
