Datasheet, Volume 2

This capability is used to uniquely identify the subsystem where the PCI device resides. 
Because this device is an integrated part of the system and not an add-in device, it is 
anticipated that this capability will never be used. However, it is necessary because 
Microsoft will test for its presence.

System BIOS can be used as the mechanism for loading the SSID/SVID values. These 
values must be preserved through power management transitions and a hardware 
reset.
