CONTROL OVER LOADING OF DEVICE DRIVERS FOR AN INDIVIDUAL INSTANCE OF A PCI DEVICE

摘要

A method identifies a plurality of PCI devices in a computer system by an associated PCI device handle, wherein each of the PCI devices is also associated with a default EFI device driver. The method further identifies a target PCI device to be disabled from within the plurality of PCI devices, provides a dummy driver that enables fewer functions for the target PCI device than would the default EFI device driver, and binds the dummy driver to the target PCI device instead of binding the default EFI device driver associated with the target PCI device. The dummy driver may be used to effectively disable the target PCI device so that the POST does not hang up or completes faster without loading the default EFI device driver.
