"My RHEL 3.0 ES linux machine is showing 256 MB of physical memory instead of 2 GB..." In the bios on our Dell servers is a parameter " OS install mode on/off" If it is on then the machine will only report 256 MB of ram. I don't know what kind of machine you have, but you might want to look at that.
