The box is really new so far I tested 2.6.24* 2.6.25 , linux-next , current git from which no one worked. And yes is right graphics under Linux didn't worked right without patch from http://lkml.org/lkml/2008/4/28/115. > > so fixing up the MTRRs during bootup, no matter how dangerous in theory, > is pretty much the best option to get your system to work fine under > Linux, with that specific Xorg version? Yes. I run : xorg-server 1.4.0.90-5 ( it has all fixes from server-1.4-branch ) mesa 7.0.2-2 xf86-video-intel 2.3.0-1 Probably I have to replace 2x2G with 2x1G to get it work without this patch but it is something I don't really want to do =) Also I'm not sure whatever this is an BIOS bug ? I could contact ASUS people if someone tells me what is wrong with the BIOS. > > i think we should still try to make this a non-default option because > modern Xorg should not have any need to touch MTRRs.
