nopentium was probably written there because you performed an upgrade from a system that already had the option appended to LILO... I think it would be very important to add this since it affects the majority of AMD cpus used with the AGP port... The change that mem=nopentium does is simply telling the kernel to use 4k pages instead of 4M pages and almost no programs can use 4M pages anyway so the performance loss is absolutely imperceptible. Many person reported big stability problems when 8.1 came out and this option can prevent that... For those interested in knowing if their CPU is affected, you can make cat /proc/cpuinfo and if the tree following lines are not identical then your CPU probably has the bug: cpu family : 6 model : 2 stepping : 2 Regards, Baal
