This is a Firebird driver for Codeigniter 2.0 +
Tested on Firebird 2.1 and Codeingniter 2.0
Put the files in the "system/database/drivers/firebird" folder and in the "application/config/database.php" you can use a configuration like this:
$db['default']['hostname'] = "localhost";
$db['default']['username'] = "SYSDBA";
$db['default']['password'] = "masterkey";
$db['default']['database'] = "databasealias"; //or "c:\mydatabase.fdb"
$db['default']['dbdriver'] = "firebird";

Good Luck
