I am attempting to get my ethernet connection working.

I have a few questions i would like some help with , if possible. ( I know absolutely nothing about ethernet, as you will read)
I have installed a SMC EZ Card, model SMC1211TX is this card any good for connecting to empeg ??

Can i connect straight from computer to empeg with this card (with correct cable, of course) (FAQ says yes as i read it)

And the broadest of all questions - Some steps for getting ethernet running, if my gear is correct, would be helpful.

I know i am asking a very open question , but i have the card left over from my DSL days, and everyone seems to rave about ethernet so i thought i might as well have a go.

But i don't really know where to start.
Windows says drivers are installed, and that's about as far as i've gotten. (yes i know, useless, your probably saying)

Ok i've rambled on enough, in short any help with ethernet connecting would be greatly appreciated!
Thanks
