I saw that comment before extending the direct map & it concerned me. But now I'm not sure that I believe the comment as the Compaq TestDrive folks have been running a 2GB XP1000 for months. In any case, I don't think the NCR/Symbios problem is related as the NCR/Symbios problem predates the extension of the direct map to cover machines with 2GB of memory. I'm hoping that the problems with having NCR/Symbios chips on the second hose will disappear when Doug's cleaner handling of multiple-hose alphas is committed.
