Okay, here's some answers for you:

1. I blew the bridges with an old AT psu I have laying around, but you can also do it with a jumped ATX psu. For blowing the bridges, I took the power lead from a dead fan and soldered sewing needles to the fan leads after cutting it off the fan. Then I carefully moved the lead that connects to the +12v out of the 4 pin socket and moved it into the +5v position in the 4 pin molex socket.

2. For hard coding the multiplier, I use this guide to look what is available and what bridges I have to blow or connect. For the 2500, you will only have to blow the 2 rightmost L3 bridges to change the default 11 multi to a 15 multi. Also, from this page , you can change the hard coding of the fsb sense speed from 166 to 133 by opening up the third L12 bridge. Finally, you will need to connect the end L5 bridge to enable your mobo to sense the proc as a MP capable proc. I used some superglue gel to fill the pit in but I've heard that it isn't necessary to do this, but I figured that I would insulate the cut anyways.

3.16 multi, it depends on how well the procs overclock. If you can max out at 150 X 15 and looks like you still have some headroom, then you might try hard coding a 16 multi.

Hope this helps you out, it took me a while to remember the websites I linked to. I forgot to bookmark the ocinside site.
