Disabling peripherals

There are different BIOS entries to disable some peripherals. But please note, due to a PCI constrain, a Device always needs a Function 0 peripheral. This means, the following peripherals cannot be disabled without disabling the remaining peripherals of the same device:

  • PCI Express Port 1 (If disabled, PCI Express Port 2 is disabled as well)
  • USB Classic UHCI Controller 1 (If disabled, UHCI 2, UHCI 3, EHCI are disabled as well)
  • SDIO 0 (If disabled, SDIO 1 and SDIO 2 are disabled as well)
  • LPC Interface (If disabled, PATA is disabled as well)
