I recently acquired a PC with an ASUS P2B-B Rev 1.01 running a P2 350.
The board revision is 1.01 which officially supports processors requiring a minimum of 1.8V, so basically no Coppermine CPUs.
ASUS made a Rev. 1.02 of this board that does support 100mhz fsb Coppermine processors, so I was interested in what were the differences, and would it be possible to somehow mod the older revision board in a similar manner.
After some digging around the net, I found this link, where it mentions you can potentially swap the voltage regulator chip, and along with the latest bios, you should be good to go:

I also found another post of someone actually trying this:

The Rev. 1.01 board has an Intersil HIP6019CB PWM controller, and the Rev. 1.02 has an Intersil HIP6019BCB PWM Controller.
I looked around on eBay and managed to find a Chinese seller that claimed to have the chip, it was cheap, so I took a chance and ordered it
The chip eventually turned up, and I took it to my friend who is good with electronics, and he said it's difficult to check the functions of the chip out-of-circuit, so he did couple of basic tests, then we just had to give it a shot and hope nothing smoked.
