Description
This field indicates to the card that it is located in the
nth socket. The first socket is numbered 0. This
permits cards designed to share a common set of I/O
ports to do so while remaining uniquely identifiable.
Cards which indicate in their CIS that they support
more than one copy of identically configured cards,
should have a copy number (0 to MAX twin cards,
MAX = n – 1) written back to the socket and copy
register.
