I added the lines: label=memtest image=/boot/memtest to lilo.conf and ran lilo. I can see the selection for memtest but it wont accept it as a bootable image. I did swap the memory out and still recieve kernel panics with known working memory. However if I boot from my old 2.2.20 kernel I will never see a panic or experience a panic after boot making me think the memory is ok. Here is the dmesg from a successful 2.4 boot if that helps: LILO Loading 2.4..................

Freeing unused kernel memory: 220k freed I have noticed that if the kernel does decide to panic on boot it will happen after the "Freeing unused memory" message is printed.
