I read somewhere that the Celeron 2 or FC-PGA celerons do not support dual processor applications, that to run dual processors, you have to spring for the PIII processors. Checked the MSI website and here is what they said in their FAQ:
Can 694D Pro (MS-6321) support dual Intel Celeron FCPGA?
Intel Celeron FCPGA CPU do not support dual CPU mode
For dual CPU mode, Celeron PPGA & P-III FCPGA is supported
So I guess the answer is no.
