The Device ID (DID) and Vendor ID (VID) registers identify the device (such as an IC), and are commonly called the PCI ID. The 16-bit vendor ID is allocated by the PCI-SIG. The 16-bit device ID is then assigned by the vendor. There is an inactive project to collect all known Vendor and Device IDs. (See the external links below.) SpletCOMMAND asks for the word-sized command register. 4.w is a numeric address of the same register. COMMAND.l asks for a 32-bit word starting at the location of the command register, i.e., the command and status registers together.
