ABSTRACT:
An embodiment of the present invention comprises a method of updating firmware of a peripheral device coupled to a computer system. A first boot operation is executed for loading an operating system into the computer system, and an update routine is installed for loading updated firmware into the peripheral device. The operating system is modified so that the update routine is executed early during a second boot operation for loading the operating system into the computer system. The second boot operation is executed, during which the update routine is executed to load the updated firmware into the peripheral device. In one embodiment, the update routine comprises an update driver having a DriverEntry code segment for loading the updated firmware into the peripheral device.
