Bads,
Did you run the installer?
Installing: Step 2 - Using the Installer
An installer is provided to assist you in entering the information Invision Power Board needs to connect to your mySQL database and to create your new administrators account.
Run the "sm_install.php" file through your web browser by entering the URL to it into your browser address bar (if you have followed our example, type in http://www.domain.com/forums/sm_install.php, naturally subsituting 'domain.com' for your web address.)
That should take care of populating the db
