It was designed for systems that had more memory than the kernel could detect, some years ago, but it also works well for telling the kernel to use less memory than you actually have, if you want to do some experimentation or something, perfect for forcing more swapping activity than you'd normally get (zero swapping ), or for watching the kernel OOM (out of memory) killer in action, if you don't have enough memory including swap. I'd know how to add it to my LILO kernel command line, but couldn't tell you how to add it to GRUB, tho it shouldn't be difficult. -- Duncan - List replies preferred. No HTML msgs.
