As you can see, the VP6 is a dual processor capable motherboard. However, it does not support ANY Celeron processors. That's right folks, this is a Pentium III only board, so be warned. You can run 1 or 2 Pentium III's in the FC-PGA (Flip Chip-Pin Grid Array) Socket 370. However, to make use of that 2nd cpu, you need to have an operating system that supports SMP (Symmetrical MultiProcessing): Windows NT/2000/ XP Pro, Linux, Unix, BeOS, BSD are examples, but their are many more.
