this might be a dumb question, but...

i'm using XP and can't use USB, i've come to terms with this and have moved on. So i use ethernet, but every time i wanna connect the Empeg, i have to disconnect from my DSL modem, and then plug the Empeg directly into the ethernet card using the crossover cable. This is a pain in the ass. Can i install a second ethernet card, and just hook the empeg up to that, or will that end in a catastrophe of some sorts?
