As I mentioned in my last message, my problem with bad RAM was on my brand new system. Memory (and, to a lesser extent, other solid-state components) will typically fail in the first 90 days or after several years. This is probably more true of memory than most chips because of the very dense nature of the chips. (I don't think I want to get into an explanation of atomic migration and the like. I really don't fully understand it myself and I'd just be parroting a friend who is a solid-state physicist.) In any case, memory that lasts for 6 months is probably good for years. This is why many Mil-specs and NASA specs require extended burn-in periods for all solid-state components. If you have two DIMMs, pull one. FreeBSD can get by with 16 or 32 MB with no problems (although some operation may slow down). If it still crashes, put that one back and pull the other. !!!Follow proper anti-static procedures!!! R.
