Major AGP Revision Number (MAJREV). These bits provide a major revision number of
Accelerated Graphics Port interface Specification, Revision 2.0 to which this version of GMCH
conforms. This field is hardwired to value of 0010b (i.e., implying Rev 2.0).
Minor AGP Revision Number (MINREV). These bits provide a minor revision number of
Accelerated Graphics Port Interface Specification, Revision 2.0 to which this version of GMCH
conforms. This number is hardwired to value of 0000 which implies that the revision is 2.0. Together
with major revision number this field identifies the GMCH as an Accelerated Graphics Port Interface
Specification, Revision 2.0 compliant device.
Next Capability Poin.ter (NCAPTR): AGP capability is 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.
Request Queue (RQ). This field is hardwired to 1Fh to indicate a maximum of 32 outstanding AGP
command requests can be handled by the GMCH. This field contains the maximum number of AGP
command requests the GMCH is configured to manage. Default =1Fh to allow a maximum of 32
outstanding AGP command requests.
Reserved.
Side Band Addressing Support (SBA). This bit indicates that the GMCH supports side band
addressing. It is hardwired to 1.
Reserved.
Greater Than Four Gigabyte Support (GT4GIG). This bit indicates that the GMCH does not
support addresses greater than 4 GB. It is hardwired to 0.
Fast Write Support (FW). This bit indicates that the GMCH supports Fast Writes from the processor
to the AGP master. It is hardwired to a 1.
Reserved.
Data Rate Support (RATE). After reset the GMCH reports its data transfer rate capability. Bit 0
identifies if the AGP device supports 1X data transfer mode, bit 1 identifies if AGP device supports
2X data transfer mode, bit 2 identifies if AGP device supports 4X data transfer
