Quick noob modem question

[sebas81]

So i have a modded SB6120(that i bought on craigslist) running great at my house and recently got a apartment and moving out, I was wondering how I would possibly access Haxorware or Forceware so i can possibly copy the settings and put them on the new modem I've purchased on ebay, (I've tried 192.168.100.1 on my modded modem and it takes me to the regular surfboard IP)unless it doesnt have either??? I will be putting the new modem preloaded with Forceware at the apartment.I know I probably sound like a noob right now but anything helps at this point. I just want to access forceware/haxorware. It seems there is not to much updated info out there.
