Rat,
You need to fill all the L1 bridges and then connect them, ssecond you have to cut the 2 right hand bridges and fill the left 2 bridges on L3.Then you must cut the 2nd right hand bridge and fill the 2 left hand bridges on L4. And lastly you have to fill the right hand and cut the left hand bridge on L10. The idea is to make your 2100 the same as a 1600xp. Look up the thread at pc stats.com"The AXP2K+ Trick-Unlocking the Athlon 2100. Or forget cutting the bridges and stuff and just do the L1's and do the pin mod on the underside of your chip.I have 2 2100's one I cut the bridges on and the other I used the pin mod,but instead of using a pin I shorted the 2 pins with defogger paint.Look up the thread with in these forums I can't remember exactly but there are people who have done this mod with much sucess as me. I do not recomend super glue I used a white crayon to fill my brides worked out great. You can used any color but I like white,yellow or orange cause its easy to see.I hope this helped you out.
