Processor Configuration Registers
308 Datasheet, Volume 2
2.19.27 SS_CAPID—Subsystem ID and Vendor ID Capabilities
Register
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.
2.19.28 SS—Subsystem ID and Subsystem Vendor ID Register
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.
