During a BIOS update of my old NUC (6i3SYH), I ended up with a "bricked" unit. After discussion on this forum we concluded I tried to jump too many BIOS versions in one update. I have acquired a replacement unit via eBay. This one is a NUC 6i5SYK. However, it has an old BIOS as well, based on the version number I can see, I think it's 0042. The current version is 0073. Clearly, I don't want to "brick" this one either, so how can I find older BIOS files so I can do a smoother update process?
With Intel only making the latest (last) available, you really don't have much choice. What is important in this case is to use the BIOS Recovery method to install the update. I recommend using the jumper-based BIOS Recovery process but, you can probably get away with using the Power Button Menu-based method. These are documented here:
- Intel NUC BIOS Update and Recovery Instructions
- Intel NUC BIOS Update and Recovery Instructions for Aptio V BIOS Core
(only the first applies to your case, but I include the second for completeness)
I also recommend being extra thorough (as Andy Grove used to say, “Only the paranoid survive."). In this case, I mean use a process like this:
- Install the latest BIOS using BIOS Recovery method.
- Install this latest BIOS again using the F7 method.
- During next POST, use F2 to enter BIOS Setup (Visual BIOS). Use F9 to reset the BIOS Configuration to Defaults and then F10 to save this BIOS Configuration and exit.
- During next POST, use F2 to again enter BIOS Setup. Make whatever BIOS Configuration changes you require (or desire) and then use F10 to save and exit.
Hope this helps,
As an added note, the problem created - and which resulted in the unit being bricked - was that you jumped too far (too many releases) using one of the regular update processes (iFlash, F7 or Express BIOS Update). It is the BIOS Recovery process that allows you to more-safely handle the big jump in releases.
