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.
