I have ASUS P54NP4 mobo. With 2x P133 - dual cpu is recognized.
But I wanted upgrade them with Overdrive MMX. During booting always 1 cpu is recognized.
Whats' limitation?

The ODPs definitely aren't SMP-capable, I'm afraid. so you are either limited to P200 (non-MMX) or need to upgrade to P55T2P4D or similar motherboard paired with a few regular MMX CPUs.

What about using interposers along with regular MMX CPUs?

Worth a try, I suppose, if you have two.
