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.
6.2.28
SS - Subsystem ID and Subsystem Vendor ID
B/D/F/Type:
0/6/0/PCI
Address Offset:
8C-8Fh
Default Value:
00008086h
Access:
RW-O
Size:
32 bits
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.
