@Fernando @MeatWar @Michael_Code A new meme will undoubtedly start “Learn to _Code”

Tried it out on my modded Asus Zenith Extreme BIOS/UEFI.
Seemed to work without hiccup. Will flash later this evening.
Used it with Python version 3.11.8
Updated UBU worked fine, I just updated the OROM for network, otherwise very straightforward update. 
Used the Annex method to flash & it went very smoothly.
Cheers
