Tyan's products page reports that there are two versions of the S2466.  
The new ones are the S2466N-4M.  The main difference listed is that the 
4Ms have functional onboard USB (v1.1), whereas the original S2466Ns 
were shipping with those addon 4port PCI USB cards.  That's why there are 
now two BIOSes for the S2466, and they warn that flashing one type of 
board with the BIOS for the other is Bad.

They must have taken the opportunity in fixing the USB problem to also 
"fix" the non-SMP chip in SMP config "problem".
