Oh man, I haven't laughed this hard in months, maybe years. I agree w/
your assessment, I was hoping someone might have a magic bullet to save
the day, but I guess not. Is the memtest86+ source available ? If so,
maybe someone else (*not* you or me) will pick it up. It was/is a nice
facility when it works. As it happens, my ongoing Passmark memtest
v6.0.0 got unstuck & has proceeded into the 2nd pass, so I may be OK
