How to find old BIOS version

[gianarb]

Hello

The download center shows only the latest available BIOS, for what I can see.

Do you know where I can find old versions? My current NUCs runs a very OLD bios, I think I broke 2 of them because I jumped too many versions. I would like to do some middle versions this time.

Thanks

Provide your NUC model number(s).

Hello

NUC5PPYB

My NUCs are running BIOS v55. I would like to go to the last one. The two that currently are not working are described here

https://community.intel.com/t5/Intel-NUCs/NUC5PPYB-bios-update-no-HDMI/m-p/1195094#M75071

But the Support was not able to help me because I didn't buy the NUCs from an official reseller

Thanks

Hello gianarb, 

Thank you for posting on the Intel® communities.   

I understand that you are facing no video problems after a BIOS update in 2 NUCs, and you think this can be due to the fact that you updated from a very old version to a very new one, is that correct? 

Currently, the only version available is the 0079 as you can check here:  

https://downloadcenter.intel.com/download/29571/BIOS-Update-PYBSWCEL-86A-?product=87740 

Please let me check internally if we have other solutions we can offer, please kindly wait for a response. As soon as we have an update, we will let you know about the outcome.

Hello gianarb,  

Thank you for patiently waiting for a response. 

While checking internally, unfortunately; did not find older BIOS versions available. This is due to the fact that Intel® does not keep track of earlier BIOS versions due to some security enhancements: 

• Additional Microcode Updates included in .ROM & .BIO Files: M01406C3368 M01406C4411 New Fixes/Features: 

• Updated BIOS code for security fixes.  

In this case, for the non-working units, please make sure you are following the correct steps for the "BIOS Recovery by Security Jumper" shown here: 

https://www.intel.com/content/www/us/en/support/articles/000005636/intel-nuc.html 

For the remaining good units, you can try several methods to update the BIOS of the same article shown above "BIOS Update and Recovery Instructions for Intel® NUC with Visual BIOS", you might want to try the "Power Button Menu Update":
