Dear Goh,
Am not sure to understand your question, if you are looking for a modification list on the software/firmware, there is none. However fluent designers generally quickly ultracompare/winmerge the source base.
If the question is how to change the BSP, then you would want to uninstall the currently installed BSP and then reinstall the new BSP. I expect difference in the firmware, nothing critical on the software.
I hope that helps,
Arnaud
