Port Number (PN) — RO. This field indicates the ingress port number for the root port. There is a
different value per port:
Component ID (CID) — RO. This field returns the value of the ESD.CID field (Chipset Configuration
Space:Offset 0104h:bits 23:16) of the chip configuration section, that is programmed by platform
BIOS, since the root port is in the same component as the RCRB.
Number of Link Entries (NLE) — RO. (Default value is 01h) Indicates one link entry
(corresponding to the RCRB).
Reserved.
Element Type (ET) — RO. (Default value is 0h) Indicates that the element type is a root port.
Target Port Number (PN) — RO. Indicates the port number of the RCRB.
Target Component ID (TCID) — RO. This field returns the value of the ESD.CID field (Chipset
Configuration Space:Offset 0104h:bits 23:16) of the chip configuration section, that is programmed
by platform BIOS, since the root port is in the same component as the RCRB.
Reserved.
Link Type (LT) — RO. Indicates that the link points to the ICH6 RCRB.
Link Valid (LV) — RO. Indicates that this link entry is valid.
