Also, in vB 2.2.9:


Find:

//load config
require("./config.php");

// init db **********************
// load db class
$dbservertype = strtolower($dbservertype);
$dbclassname="./db_$dbservertype.php";
require($dbclassname);

$DB_site=new DB_Sql_vb;

$DB_site->appname="vBulletin Control Panel";
$DB_site->appshortname="vBulletin (cp)";
$DB_site->database=$dbname;
$DB_site->server=$servername;
$DB_site->user=$dbusername;
$DB_site->password=$dbpassword;

In vB 2.2.9 you won't be able to find that bit of code. The config.php part is higher up in the file.
