Ss_Capid-Subsystem Id And Vendor Id Capabilities (D1:F0); Ss-Subsystem Id And Subsystem Vendor Id (D1:F0) - Intel 925 - Pentium D 925 3.0GHz 800MHz 4MB-Cache Socket 775 CPU Datasheet

Host-PCI Express* Graphics Bridge Registers (D1:F0)
8.1.25 SS_CAPID—Subsystem ID and Vendor ID Capabilities
(D1:F0)
PCI Device:
Address Offset:
Default Value:
Access:
Size:
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.

RO Pointer to Next Capability: This field contains a pointer to the next item in the
80h capabilities list which is the PCI Power Management capability.
RO Capability ID: A value of 0Dh identifies this linked list item (capability structure)
0D h as being for SSID/SSVID registers in a PCI-to-PCI Bridge.

Default
R/WO Subsystem ID (SSID): This field identifies the particular subsystem and is
0000h assigned by the vendor.
R/WO Subsystem Vendor ID (SSVID): This field identifies the manufacturer of the
8086h subsystem and is the same as the vendor ID that is assigned by the PCI Special
Interest Group.
