Well, a switch of the memory (four 4x32s -> two 8x32s) and a more effective cooling fan seems to have solved the problem. I don't know if it was the memory or the fan that did it, but the bottom line is that FreeBSD can work with the 6x86 and this motherboard if the conditions are right. I have seen several posts in other groups making note of the temperature sensitivity of the 6x86. Also, the ASUS guys tell me some 6x86 flakiness can be cured by using a higher voltage than the recommended 3.3V - at least that's what the Cyrix people told them. Larry
