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.
