What kind of motherboard are you using ? bios version ? Memory type ?
But you could try a "linux mem=512M" at lilo time your testing if it's a
memory detection problem.If you need an initrd for booting your node and if the memory detection is
not working fine the initrd can't be loaded in RAM then you can't boot.
