Lasse, you need to crank up the front side bus speed. Does your P2-400 have 66MHz or 100MHz FSB now?
Disclaimer: use this info at your own risk!
If it is 66MHz, the clock multiplier is 6. 66x6~400. If it is 100MHZ, the multiplier is 4. The multiplier is locked, you cannot change that. So what you need to do is get the motherboard manual and see how to change the FSB speed. From what I understood, you can do it straight from the bios, which is good.
If the speed is 66mhz now, crank it up to 75. You should now have a P2-450. Run your computer for a long time (3+ hrs) on very high load, any new flight sim will do. If it works all right with no crashes - congratulations. Jump into bios and check your cpu temperature (if you have a meter there). If it is under 45 degrees C, you are pretty much safe to overclock even further. 83MHz fsb will give you a P2-500. But that will strain your harddrives, video card and other stuff pretty far, because of the higher bus speeds. If you would get it running at 100 fsb, you'd have a P2-600. Not bad

But, if your cpu already is a 100 fsb, forget those figures I wrote. In this case you need to increase the fsb over 100. I havent oc'd a 100mhz fsb chip before, so I'm not sure how the speeds go. I think its something like 112 and 125. Try 112 first, just like I explained above.
If you have one of those new boards with adjustable fsb speeds, good. It gives you more options

I don't recommend increasing the cpu voltage to get the oc'd cpu more stable. But if you do, remember to add cooling fans!
