That's one of the beauties of Linux: unlike a competing "operating system" which shall remain nameless (but is headquartered in Redmond, WA), it'll run on pretty much *anything*. It will find more hardware errors... because it uses the entire system much more efficiently. But if the hardware's ok, it'll run for a *long* time. So, yes, anything you've got should work. mark
