Besides the bios look in the device manager for the item there and right click on it to select the disable option. You download the latest update for the X1300 model right from the support site to see the latest Catlayst version and drivers installed.
The latest Catalyst 8.3 version 44.2mb download for that model is available at AMD GAME Drivers And Utilities
The second item seen there is for the drivers only is the 14.1mb driver set. You simply download the update and save it in a folder. The installer for the Catalyst(preferred) will create a new ATI folder in case you have to reinstall the update at some other time you simply run the setup.exe file again.
