Asus p2b-d + p3 650

Hi, so, i have this awesome board (p2b-d) and i ran it for years with 2x350 mhz p2, i also tried the board with a p2 400 (100 mhz fsb) that also worked.

Now i got 2 P3 650 Mhz (also 100 mhz fsb) and it dosent work at all, the board just blinks with the power and harddrive led.
It does the same if i start it with no cpu at all..

Ofcause on asus webpage the only thing there ISENT there, is the manual..

1000xInternets to whom can find a manual or even just a listing of how to set jumpers for diffrent cpu speeds, or any help at all actually ! :)

Thank you.

Also alternatively, you could make the jump to modern hardware, where a $80 processor can rape your old setup with ease. Just sayin'.
