The problem is not with the motherboard. Most of the mother boards that support SMP PII's have the same problem. I was unable to locate where in the configs the problem comes from though. I was testing dual PII 400 when they were first avalible from Compaq with 1.0 gig of 256meg dimms. They are recognized fine by the bios but FreeBSD won't work with it. I tested NT, Novell, and Sco all of which work although no where near as well and the system with 512meg and SMP FreeBSD. Rob.
