Major AGP Revision Number: These bits provide a major revision number of AGP specification to
which this version of GMCH-M conforms. These bits are set to the value 0010 to indicate AGP Rev. 2.x.
Default Value=0010.
Minor AGP Revision Number: These bits provide a minor revision number of AGP specification to
which this version of GMCH-M conforms. This number is hardwired to value of 0000 (i.e. implying Rev
x.0). Together with major revision number, this field identifies GMCH-M as an AGP REV 2.0 compliant
device.
Default Value=0000.
Next Capability Pointer: AGP capability is the last capability described via the capability pointer
mechanism and therefore these bits are hardwired to 00h to indicate the end of the capability linked list.
Default Value=0000/0000.
AGP Capability ID: This field identifies the linked list item as containing AGP registers. This field has the
value 02h as assigned by the PCI SIG.
Default Value=0000/0010.
