Major AGP Revision Number (MAJREV). These bits provide a major revision number of AGP
specification that this version of the MCH conforms. This field is hardwired to value of “0010b”
(i.e., implying Rev 2.x).
Minor AGP Revision Number (MINREV). These bits provide a minor revision number of AGP
specification that this version of the MCH conforms. This number is hardwired to value of “0000”
(i.e., implying Rev x.0)
Together with the major revision number this field identifies MCH as an AGP Revision 2.0
compliant device.
Next Capability Pointer (NCAPTR). AGP capability is the first and the last capability described
via the capability pointer mechanism; therefore, these bits are hardwired to 0h to indicate the
end of the capability linked list.
AGP Capability ID (CAPID). This field identifies the linked list item as containing AGP
registers. This field has a value of 0000_0010b assigned by the PCI SIG.
