I'm surprised that Memtest gives different results depending on what
disk you run it from,  I guess it would be a good idea to download a
stand-alone version and run a sanity check on the download.  BTW,
Memtest has been around forever.  I think I first saw it around
1990, or maybe even earlier.

How do you check to see how much memory your system has
available to use? Obviously, you have to test that from within the OS.
