FORGET about the NPS displayed by Chess Tiger until you set the speed to the
right value, with the process I have described already.

The clock (time measurement) of the Palm is BROKEN when you overclock too much.
Because instead of running faster, your Palm actually runs SLOWER.

YOU SET IT TO 54MHZ AND YOU ARE HAPPY, BUT YOUR PALM RUNS MAYBE AT 15 OR 16MHZ
(or whatever).

If the clock is broken, naturally the NPS displayed is broken as well.

That's why you need an external clock in order to find the highest frequency
your Palm can run at, while achieving a correct time measurement.

Most probably your are going to find out that your m100 cannot run higher than
29MHz. You'll get a TigerMark of 1.0x (which is not bad, and more realistic).
