By the way how and where exactly would I append Lilo with the 'lilo append mem=nopentium'? I would very much like to try this option since I continue to have to reboot to get most things working. Would it be worth it for me to get XFree86-4.2.1? I know I am not having overheating problems. I have extra cooling. I have Windows 95 as a dual boot and it seems to do fine. I am a newbie still and I need exact instructions. Thank you very much for your ideas and input.
Sincerely, Marcia
