Abstract
The present invention is a method and system for firmware management. A clipped copy of the firmware associated with a device may be built within the boot image of an appliance. Alternatively, mathematical signatures of the firmware associated with a device may be stored in the boot image of an appliance. Advantageously, use of clipped copies of firmware and mathematical signatures of firmware within the boot image may preserve boot image space while maintaining the integrity of the boot procedure of the appliance. Additionally, a method and system of mitigating firmware corruption is provided by flashing a boot block portion of device firmware only when an update is necessary.
