SS_CAPID—Subsystem ID and Vendor ID
Capabilities
B/D/F/Type:
0/6/0/PCI
Address Offset: 88–8Bh
Default Value:
0000800Dh
Access:
RO
Size:
32 bits
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.
