I'm quite puzzled at all this sudden invective aimed at Tyan, considering that it's definitely my motherboard of choice, and wonder if this isn't perhaps a voltage problem or something. I was recently talking to a friend of mine who uses a bunch of Tyan MBs and he was recounting this odd problem he had where this one machine was getting sig-11s and generally failing to install (it would panic at various places in sysinstall). He racked his brains for some time until one of his buddies mentioned that he'd been talking to a Tyan support engineer who mentioned in passing that if you have your DIMMs set for 5V instead of 3V, some definite weirdness would occur. Off goes my friend to check and, sure enough, there *is* a jumper for the memory operating voltage and it was set to 5V. Once changed, the machine performed flawlessly. Just FYI. Jordan
