How to check oscillator frequency

[Johan]

Thanks Steve,
It was my mistake , I looked at C:PBP\INC folder instead of C:PBP, that's why I never found the 18F4431.INC file.

Now, it it configured as your suggestion, and it works ( The Configuration bits on Picflash changed as well , save me some clicks, thanks )

One more thing, I 'd like to know more about HS PLL mode ( Datasheet 2.3 ). Suppose I want to use external 8 Mhz crystal to produce 32 Mhz clock, what settings are required ?
