Tom_ZJP: Thank you very much for contacting the Intel® NUC communities. We will do our best to provide the information you are looking for.
In regard to your inquiry, depending on the BIOS version, if there are some problems reported with that version, most of the times there are fixes to it, but sometimes that version can get removed for a new one that contains the proper fixes and solutions depending on the specific scenario.
Depending on the model of the NUC, we can always look for a newer BIOS version in our web site, there might be a new one available now:
Any further questions, please let me know.
