I am trying to add more memory to my Linux box. The specs on the box state that it is upgradable to 2GB. I added a 512MB stick in addition to the 128MB stick and I could not configure it past 384MB. I changed the order of the sticks, I entered append "mem=640M" in the lilo.conf and ran lilo. To test the memory stick, I put it in another computer (WinXP) and the full 512M showed up. I put a 256M along with the 128M and the results were the same as when I had the 512MB. Is there a configuration or kernel parameter I need to change or has someone run into this situation before?
