This controller is not removable, but you can disable it by installing a PCI video adapter. Note: If you install a PCI video adapter, the server BIOS will automatically disable the integrated video controller. The integrated video controller is located on PCI bus A (slot 1) on the system board. See "Adapter considerations" on page 53 for detailed information about the PCI buses in your server.
