How do I tell yum to install the PAE kernel automatically or do I have to specify yum install kernel-PAE kernel-PAE-devel kernel-PAE-headers when I update to latest kernel? > > What does the PAE kernel offers or does better than the regular kernel? > > I tried google, but it does not give me satisfactory answers. I am sorry to bother with an elementary question, but I want to know what is better for my system. I also want to know if I get nvidia driver, how does it fare with PAE kernels?, I play a dvd and I see: > > > ************************************************ > **** Your system is too SLOW to play this! **** > ************************************************ > > Possible reasons, problems, workarounds: > - Most common: broken/buggy _audio_ driver > - Try -ao sdl or use the OSS emulation of ALSA. > - Experiment with different values for -autosync, 30 is a good start. > - Slow video output > - Try a different -vo driver (-vo help for a list) or try -framedrop! > - Slow CPU > - Don't try to play a big DVD/DivX on a slow CPU!

Your 3GB is within the address range of the "standard" 32-bit kernel. You need to have 4 GB or more in order to trigger a requirement for PAE.
