XLR Posted February 24, 2014 Share Posted February 24, 2014 Try PCIRootUID=1 and npci=0x2000, both commands seperated by a space bar. EDIT: i see you're using some distro, if you want your computer to work properly - you have to use a vanilla installation instead. Link to comment Share on other sites More sharing options...
