OK, replaced old NForce2 mobo, Athlon 2500+ (Socket A) CPU, and 1 stick of 512 MB PC2700 RAM with new NForce4 mobo, Athlon 64 3500+ (S939) CPU, and 2 sticks of 512 MB PC3200 RAM.
Gwen took the old stuff apart, and put the new stuff in. I supervised.
Plugged in the box and …
… wouldn’t you know? It just worked.
Windows XP came up fine. Didn’t complain about a single thing. Nada. It tried to install new drivers, of course, and 2 reboots later, I’m writing this on the “new and improved” machine.
And, don’t you know, that I had prepared Gwen with the whole “well, even if this does work, it’s going to take a while to get everything back up and running. Best case… Worst case… etc.”
I like it when things work better than expected.
