Help Overclock XP2200

[xSeongminx]

Hey, I have a XP2200 T-bred cpu and was wondering how I could get the most out of it. Since my mobo fried a month or two ago, I purchased a new one from the forums. It's the biostar m7ncd which is pretty good, given it's price, but when it comes to overclocking, there are no options in bios except for raising the fsb. Now my question is, how would I go and perform the wire mod to raise voltage and how would I unlock the multipliers? Also, since I don't have an agp/pci lock, am I severely limited to the cpu's potential (I ran this cpu at 2.4 gigs with the other mobo)?
