CPU Speed

How would I go about calculating the clock speed in Mhz of a CPU?
I don't want to call the speed from CMOS/BIOS but calculate it real time.

I used to have a program that did this, but I lost it years ago.

Thanks in advance :)

Kinda like the BogoMIPS 'feature' in Linux?  I guess, AFAIK, you'd get a
sereis of difficult, complex calculation and time how fast it takes to
calc them.

Careful with that; BogoMIPS is _not_ a performance measure by any
means.  My P5-mmx @ 166MHz gives me 333.31 BogoMIPS, while a plain
P5 @ 166MHz gives 66.4 BogoMIPS.  Try the following file; it should
have all that you need:
