Thanks for letting me know about the program JJB6486.
I just ran MemTest-86 ver 3.0.
This is very cool.
The only strange thing is after you install the contents onto the floppy, XP thinks the floppy is not formated. Rebooting the system the program starts right up. I ran the test for over 5 hours and everything is just fine. I have 512 MB of RDRAM.
