| + | **busid** This yields a five-byte hexadecimal code representing the adapter's bus type, followed by the two-byte vendor ID, followed by the two-byte device ID. This could be handy for fetching an initrd or other RAM disk image containing the OS driver for the particular network adapter. For example: | ||
