You can add it by hand: lspci -v find VGA compatible controller record ther whould be Memory at (location) (32-bit, prefetchable) [size=256M] (instead of location there will be particular address (in my case d0000000)). Once you have the location, you can do: echo "base=0xlocation size=0x10000000 type=write-combining" >| /proc/mtrr in my particular case it is: echo "base=0xd0000000 size=0x10000000 type=write-combining" >| /proc/mtrr -- Lukáš Hejtmánek </blockquote></div> -- ------------------------ Chris Monahan
