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.

A method of updating firmware of a peripheral device coupled to a computer system, the method comprising:
- executing a first boot operation for loading an operating system into the computer system;
- installing an update routine for loading updated firmware into the peripheral device;
- modifying the operating system so that the operating system executes the update routine during a second boot operation;
- and
- executing the second boot operation, during which the update routine is executed to load the updated firmware into the peripheral device;
- wherein:
- the operating system configures the peripheral device during each boot operation;
- and
- the step of modifying the operating system further comprises modifying the operating system so that the update routine is executed prior to the operating system configuring the peripheral device.

- executing a first boot operation for loading an operating system into the computer system;
- installing an update driver for loading updated firmware into the peripheral device;
- modifying the operating system to execute the update driver during a second boot operation of the computer system;
- executing the second boot operation, during which the update driver is executed to load the updated firmware into the peripheral device;
- and
- uninstalling the update driver;
- wherein:
- the operating system configures the peripheral device during each boot operation;
- and
- the step of modifying the operating system further comprises modifying the operating system so that the update routine is executed prior to the operating system configuring the peripheral device.

- installing an update routine for loading updated firmware into a peripheral device coupled to the computer system;
- and
- modifying the operating system so that the operating system executes the update routine during a boot operation;
- wherein:
- the operating system configures the peripheral device during each boot operation;
- and
- the step of modifying the operating system further comprises modifying the operating system so that the update routine is executed prior to the operating system configuring the peripheral device.
