Fraid not, but I'm starting to see the value of that feature ;-)

Yup, that one specifically.

Correct. This is what leads me to believe that the motherboard is damaged.
Specifically the fact that it acts like the PS has been shorted.

Yea, I wasn't sure about that. 
It does start without the processor installed though (by start I mean the 
power supply fan spins up. Of course nothing else actually happens)

I'll check that tonight.

Not yet, I'm a little scared to do that, fearing I might destroy it as well.

Doesn't get the chance to beep or try posting, if I put the 4 pin CPU power 
connector (I'm assuming that's what it is) in place, I get no power.

There just don't seem to be as many motherboards in this form factor, and they 
seem to be a little pricier, at least where I'm shopping (newegg and tiger)
Functionally it's fine.

Doe!, wish I would have found this earlier. 
I did find some crazy guy on Amazon that's selling an XP2600 for $60.
And I guess their stuff is guaranteed....

Yea, I was thinking about that.
I just don't want to reinstall my OS and try to reconfigure everything for 64 
bits right now, It was working so nice until it exploded.

thanks for all your advice!
