Why have I not found it?

[The Astroman]

I was looking out of interest to see if there existed 2 processor mobos, but only found bi Xeon and bi Celeron but no bi Pentium 4... Is this technical or will such a mobo come out in a near future?

Pentium4 chips cant handle SMC (unlike the AMDs which can, in a pinch, be subsituted, to a degree). The Xeon IS the Pentium 4
