I have searched the forums and looked at the Definitive Guide FAQs, but cannot answer this simple question.

I used to use BT1 and BT2, it has been awhile and now I see BT4 is out (wow time flies). I burned the iso to a DVD and booted from it, although at the root@bt: prompt, the usual 'bt' doesn't load backtrack. What am I missing?

I did a ls on the contents and got install.sh, so tried to sh install.sh but didn't get any further. I was familiar with BT 1 and 2, but am not so familiar with slax.

Can someone help me get past this and into BT? This seems so easy yet I'm spinning my wheels.
