Okay, thanks to jssmod and radarman, I now have a fully operational mobo. I have been succesful in loading XP on a bigger HD. All of this has been accomplished with the help of an external PS, external monitor, and 'grown-up' usb keyboard and mouse. Now it's time to put the guts back into their new home.....HELLO problem #2!
It's worth noting that the replacement mobo I ordered didn't have 2 sets of pins assembled on the board:
1) Pin set labeled as j1d3 (on the original board). This is labeled as AUD on the original board, I didn't think this would be a bid deal, as the replacement board has AV jacks on the board.
2) Pin set labeled as j3a1 (on the original board). This labeled as FP2... This pin set is paralled to the PCI slot, and on the edge of the board (18 -1 pins).
Anyway. I assembled this jigsaw puzzle that is the dot station, but when I plugged it in I got nothing. The fan for the monitor didn't even come on. Odd thing is this: I can unplug the video cable and the fan will twitch, and the monitor will come to life (obviously with no signal). Through all of this, the PC itself never powers up. I can't hear or feel the HD spinning up.
Do you guys have any more pearls of wisdom for me?
Thanks again for all of the help.
