Motherboards compatability

I need to know a motherboard that will work with QNX, will support the intel PRESCOT 800 FSB cpu, and on which the SMP kernel will be able to see both logical CPU’s.

I bought an ASUS motherboard recently and QNX 6.3 runs on it, but the SMP kernel, for reasons unknown, doesn’t see both logical cpu’s.

I have an MSI board that runs QNX 6.3 and sees both logical CPU’s in the SMP kernel, but I’m not running a PRESCOT. But I’ve had bad experiences with 3 MSI motherboards and I don’t want to depend on them anymore for mission-critical systems.

So: I need to know a specific make/model of motherboard that will work with QNX 6.3, and on which the SMP kernel will see both logical CPU’s.

Anyone?
