PIII FC-PGA New Stepping:
Based on the information I have been given, the new core stepping (cB0) of the PIII FC-PGA copermines will have SMP support. Speeds range from 500 MHz-866 MHz - using the 100/133 MHz FSB. There is a 1 GHz FC-PGA listed in the Intel spec sheet, but does not have SMP support.
Click here to download the Intel PIII Specification Update sheet. ( This document contains all S Spec #'s for the previous and upcoming PIII's on pages 14-18 )
( Note: The old stepping is (cA2) and so far I haven't seen any FC-PGA's with that stepping which would support SMP. ) Your best bet will be the (cB0) stepping.

Voltage Settings for the FC-PGA:
533EB, 550E, 600E, 600EB, 650, 667B, 700, 733B, 750, 800, 800EB, 850, 866
The Abit BP6 supports 1.3V to 2.3V
Do all coppermine FC-PGA cpu's support SMP(symmetric multi processing)?
Answer: No, not all support SMP. The newer core stepping recently released by Intel is supposed to support SMP. The old stepping is cA2, the new stepping is cB0.
Currently the Pentium III processor in the FC-PGA package does not support dual-processing. The processor has been hardware disabled for such functionality. Future versions of this processor may include this feature.
However, the Pentium III processor in the S.E.C.C.2 package is designed for dual processor (DP) operation. The following information pertains only to the Pentium III processor in the S.E.C.C.2 package...
