I expect you are running the stock xandros version of linux that the EEE701 came with.
I suggest you head over to
http://wiki.eeeuser.com/
Then install KDE (AKA "Advanced mode") :
http://wiki.eeeuser.com/#full_desktop_advanced_mode
Then read about how to start a program at startup:
http://wiki.eeeuser.com/howto:startupscript (which, basically, tells you to put a script calling the program you want to start in the directory
/home/user/.kde/Autostart/ )
Your script will probably look something like this
Code:
#!/bin/bash
firefox http://www.radio.com/channelNumber
