I ended up just re-installing the 2000 OS over it. Just had to adjust the bios boot order. It worked great! Now I can setup the comp just the way I want it...
Still gotta install more Harddisks and figure out dual booting, ah more research... and will probably rip this comp down to its pieces again, once I'm sure I've gotten it running well now.
Thanks for the help everyone. Good luck with your probs.
