I know what you are talking about. I got a celeron 300 that I wana do the same thing. It's an old compaq motherboard with the jumpers all over it. I know It had a p3 450 i think at one point.... I'd like to know how to too!
Look for jumpers to change fsb from 66 to 100. That'll overclock it. If there aren't jumpers for it, and it's auto sensed by bsel pins / slot, then you'll have to look up the datasheet for how to change bsel hi/lo with either conductive ink or tape/superglue/something

Yep... there should be jumpers on the board to change the FSB. There should also be some silkscreening on the board, near the jumpers that will show you which pins to short out for the speed you need.
::Sigh:: I miss the Intel BX chipset... it was so good to me.
Didn't have a whole lotta luck overclocking my 366, but that celeron 300a... what memories!
Good Luck guys
Edit: after reading kill4killin's post... I remembered something. If your board uses jumpers to adjust FSB speed instead of BIOS adjustments, it probably also uses jumpers for multiplier adjustments as well... don't forget to change those, cause like k4k said, your chip may not be able to handle the new bus speed with the default multiplier setting.

The best way I found to do it on my slot1 machine was to use the non-conductive tape method. You simply find pin B27 (I think thats right) and put a very small piece of electrical tape over that pin and hope it stays on when you put it in the slot. You may also need to change the jumpers around on your motherboard in order to get it stable because I know that my 100mhz FSB PIII was able to pull it off with the full 8x multiplier however, if your chip default runs at 66mhz, the full 133mhz may be to much for it to handle with the full multiplier.

Can hardly remember what I had for dinner last night... you want me to remember something from almost a decade ago?
That's probably why I chose the motherboards I did back then... instead of using a jumper to bump you from 66MHz, to 100MHz, to 133MHz... it was all done in the BIOS.... 1 MHz at a time. The only thing I can remember for sure... was the Intel BX chipset never gave me a lick of troubles.
