I think you're out of luck, but there might be a way to get it to work.
The problem is that you have a slot1 CPU and its supposed to run @ 1.65 CV, but the P2B doesn't like 0.05 V adjustments, also the older P2B's only go down to 1.8V (the newer P2B's go down to 1.6V).
It MIGHT work when you do some VID "wiring"/Taping, but I need to know which revision you have (look between the 1st and 2nd ISA slot) and/or if you want to OC it, cuz you might be able to VID tape it to 1.6V but that won't be good for OCing.
You also need to have the latest BIOS (1012 or up).
The other peeps that got it to work probably used a FC-PGA chip with a slocket.
Let me (us) know if you're willing to try the VID taping, and I'll D/L the datasheet and have a look what the possibilities are.
I can't guarantee you that it will work (your taking a small risk damaging the CPU, but you might have damaged it already).
