BIOS and IPMI Firmware update for Supermicro X11SSL-CF

Howdy free Nas community! Long time no see! I hope everyone is well :) now onto the question: suppose you want to update both the BMC/IPMI firmware and the BIOS, is it better to first update the BIOS And then the BMC, or is the other way around better? Reason I might want to do this is because I ran into the IPMI KCS error again.

Question 2: Does any one of you have experience with out of band updates? I have an activated license, but I see, to remeber you had to upload a bios file, and i do note rember if it was the entier zipfile or just one of the files in the bios zip.

Thanks for the help in advance.

Did you decide upon a workflow for this? If so, did it work out?
