In the console I see only two messages: april 20 | july > 4. It won't help. I wouldn't waste your time if I were you. I've dealt with these MSI boards in the past, and they're cheap luhsuh. Again, my understanding is that the ethernet card is crap, and occasionally just wedges of its own accord. After a few milliseconds, the watchdog goes off and triggers a hardware reset. A few packets get dropped and need resent, but TCP is a "reliable" protocol so nobody notices. Want to see just how bad the card is? Do some performance tests and see how close to the theoretical network maximum you can get on data transfers. If I remember correctly, we only got about 50% of was the card _should_ have been able to accomplish. The difference between the drivers provided by SIS and those built in to FreeBSD is that the SiS drivers for Windows will never tell you what's going on, whereas the FreeBSD drivers will log every time a hardware reset is required. -- Bill Moran Collaborative Fusion Inc.
