Dimension 4100 CPU compatability

I found an old socket 370 Pentium 3 (Celeron, maybe) Tualatin 1.4 GHz, that runs a 100MHz FSB, has 256k L2 cache.

I have an old Dell Dimension 4100 that I use quite a bit, but the CPU is feeling its age, so I was curious if I could put this CPU into this motherboard. I don't want to put it in just in case a voltage mis-match fries the mobo/CPU, which I cannot allow.

Currently the Dell has a socket 370 Pentium 3 Coppermine 800Mhz, runs on a 133 FSB, and has 256K L2 cache.
 
Dang.

What does the adapter do, exactly? Does it just change the voltage, or is the pinout on the Tualatins different than the pinout on the Coppermines?
 
Check out this article which compares the Tualatin to the Coppermine.

It looks like the Tualatin has a different pin config to allow for smaller voltage increments. Both CPUs are Socket 370, but the Tualatin is FC-PGA2 and the Coppermine is FC-PGA. Bottom line, Anand clearly states that the Tualatins don't work in Coppermine-only mobos.

The only alternative to the adapter would be a universal Socket 370 mobo (see p. 5 of the article) - again, not sure how easy it would be to obtain one of those.

Good luck!
