Openbox is basicly a Dreambox clone. First you have to download a appropriate image. I use and like Openpli. Images here: http://www.sat-universe.com/showthread.php?t=210858 Make sure you get one that matches your bootloader (SSL) and SIM card.
Turn power on while holding the power button for +/- 10 seconds. A IP address will appear on the box screen. Use your browser to go to that IP address. The browser will open a page that somewhere has a button (text) to click to install your new firmware. Follow instructions. Turn CCcam on. Put your indovision card with contacts up. Scan the transponders for channels and voila you have Indovision on a OPenbox. You don't need BOXID.
Telkomvision is exactly the same.
PS. This is something your vendor all should have done...
