It takes around 8 hours on my laptop The major downside is that software memory testing isn't conclusive. If it detects a problem, you've probably got one. If it doesn't, you may still. The only way to be sure is to use a hardware tester. If you don't have one, and most of us don't, you have to resort to swapping memory. : -- dscheidt@tumbolia.com Bipedalism is only a fad.
