If you have a network card, just plug everything in between the stb & pc, boot the stb, wait for the 2 lights to lock, then boot the pc, check your Ip (win 98 & Me, click start, then run & type winipcfg, make sure that your nic is displayed not the ppp adaptor. 2k & xp start, rin, type in cmd, click ok, then type ipconfig & hit enter) you should have an ip starting 10.
if you do, open up Ie, you may need to run the Ie wizard, but if you are lucky you should just have to type into the address bar, start.ntl and then click go, or try the ip addresses 172.16.30.35 if that one does not work swap the 35 for 83 or 84, then just enter your 10 digit pid no & password and off you go add the pc & go through the rest of reg
