Reserved.
Major AGP Revision Number (MAJREV): These bits provide a major revision number of AGP
specification to which this version of MCH-M 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 to which this version of MCH-M conforms. This number is hardwired to value of “0000”
(i.e. implying Rev x.0)
Together with major revision number, this field identifies MCH-M as an AGP REV 2.0 compliant
device.
Next Capability Pointer (NCAPTR): AGP capability is the first and the last capability described via
the capability pointer mechanism and therefore these bits are hardwired to “0” 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.
