I have been using my notebook off and on and recently retrieved some crucial data from it. However, today, when I tried to boot it, I get the message "Operating System not found" right after BIOS and Setup. Any idea what is happening? It is a p2-266 running win98. The only thing I noticed oin the Setup that looked wrong is that the Primary Master was set to "none" so I changed it to "auto" but still no happiness. Please do enlighten! thnx, hj.
