Methods and systems are provided for recovering configuration data in a computer system. According to one method, a device is selected as a current device. A first map location is retrieved from a layout of present configuration data stored in a computer system. Next, a second map location is retrieved from a layout of updated configuration data stored in the computer system for the current device. A determination is then made as to whether the first map location matches the second map location for the current device. If it is determined that the first map location matches the second map location for the current device, then the next hardware device in the set of devices is selected as the current device. If it is determined that the first map location does not match the second map location for the current component, then the present configuration data is copied from the first map location to the second map location in an NVRAM, the present configuration data is erased from the first map location in the NVRAM, and the next hardware device in the set of devices is selected as the current device.

Method and system for recovering the configuration data of a computer system

Methods are provided for detecting the validity of configuration data and recovering configuration data in a computer system. A layout of present configuration data is detected in the computer system. The present configuration data is stored in a memory device which may be a non-volatile random access memory ('NVRAM') device. Next, a layout of updated configuration data for the computer system is detected. The updated configuration data is stored within program code, such as a BIOS, which includes an updated configuration for the computer system. Next, the layout of the present configuration data is compared to the layout of the updated configuration data in the computer system. If the layout of the present configuration data matches the layout of the updated configuration data, then it is determined that the present configuration data is valid configuration data for the computer system. If the layout of the present configuration data does not match the layout of the updated configuration data, then it is determined that the present configuration data is invalid configuration data and the present configuration data is either reset to a default state or recovered into an updated memory location in the NVRAM.
