There is a "mem=" kernel option at boot time. If this is a Dell server,
there is a bios setting for memory and I don't remember the exact name
of the setting, but it's in the memory section and it mentions OS. If
this is set to ON, the bios thinks the OS cannot handle more than 256M
of memory, and that's all the OS will see.
