Details of connecting beagleboard-xm to linux-mint pc

Hi all,

I have beagleboard-xm. I have ported Android - ICS on it. I want to get ip address of the board. As said on site, i connected the board using mini usb cable and clicked on http://192.168.7.2 but it did not open the page. Also if i type ifconfig on terminal of my pc it does not show USB0 or something like that… It only shows 'eth0 and ‘lo’. Where is the problem ??

As i have already said i have build Android ICS on the board, at that time i have used serial to usb cable to the board. Board is working well with Android ICS. I used minicom fot that.

But how to get the IP address is the problem for me…
