PCI CONTROLLER
4.1 VENDOR IDENTIFICATION REGISTER (VID)
The VID register contains the vendor identification
number. This number is assigned by the PCI Special
Interest Group and is intended to uniquely identify
any PCI device. Write operations from the PCI inter-
face have no effect on this register. After reset is
removed, this field can be boot-loaded from the ex-
ternal non-volatile device (if present and valid) so that
other legitimate PCI SIG members can substitute their
vendor identification number for this field. Sections 7.2
and 7.3 detail the optional boot-load operation.
