Hardware's working fine now, and everything's ticking along great, except for two things.
First, I'm not sure that both cores are being used in the processor. As far as I can tell, I'll need to reinstall XP to activate it, which will bollix up what settings I've got now.
Second - I've got a fair bit of stuff downloaded from Amazon's UnBox service. And the machine's changed sufficiently that my Digital Rights Management licensing is pretty much nonexistant at this point.
Gotta love it... Any advice, anyone?
