Description
0
SERR on Access to Invalid Graphics Aperture Translation Table Entry.
0 = reporting of this condition via SERR messaging is disabled.When this bit is set to “
1 = the GMCH2-M generates an SERR hub interface special cycle when an invalid translation table
entry was returned in response to a AGP access to the graphics aperture.
