Well, well, well... Look what I found:

I got this in an old system that a friend of mine gave me a while ago.
Good news: It's an exact match for the CPU I have installed.
Bad news: It is out of one of two systems I was given - one of which was hit by lightning. Don't know which one.
Good news, is that both PSU's powered up when plugged in.
Bad news, didn't have a chance to hook it up with a hard drive & monitor to test it.
Good news, this is the system the memory I added to my system came from - it's tested good.
Wish me luck!
The BIOS Dance® will have to wait for another night - got tied up with unexpected company tonight - haven't even had time to eat more than an orange...
Thanks everyone!
