It's running for 15 minutes now without any warning; I'll let it run while cooking a meal [ with 2*1G mem for each CPU to be clear ]. NB, (CC to kris@ for this) why is memtest86 port marked as i386-only? It only seems to install floppy.bin and memtest.iso, but alas (maybe I should leave one box dedicated to freebsd-i386 for things like this ;) ) Best, Arno
