Sorry for my english.

This is my first message.

I have the problem to install backtrack 2.

I rebuild the orignal iso file with ultraiso.

I plug the file ati.lzm in bt/modules directory.

When i start the live cd the program give me an error(no screen found).

I type root,toor,ati then the message is:

/usr/bin/ati: line 2: aticonfig: command not found



My notebook is a toshiba m60,ati mobility radeon x700,card wi-fi intel pro wireless 2200bg.

Somewone can help me.

Tanks....

You can use magiciso to burn this iso file. It works fine for me.
