As I've found new information about the VP6, I thought I'd post about it in case there are other VP6 FreeBSD users out there. A Steven E. Smith suggested I swap my CPUs, which I did to no avail. I'd like to pretend my system is more stable now, but I don't think it is. Recently, I discovered an article (http://www.vp6-board.com/caps1.htm), which makes mention of faulty/poor quality capacitors. For now, I'm taking the article as gospel and going ahead with the changes. Since I had a BP6 with a blown cap, I decided to work on that board before going ahead with the VP6. Also, someone posted (here) an article about issues with the BP6, so I added that to the job. Since the BP6 repairs were so successful, I went ahead with the VP6 repairs yesterday. I'm happy to report that my system is incredibly stable now and I can actually use both CPUs. Prior to this, I couldn't boot into SMP or, if I could, it would only be for seconds; even UP was extremely unstable. -- -Dale To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
