Dare I suggest if Rock is working fine, don’t worry about the bios update. Although the Kb suggests it , it’s been sometime since that was written, therefore your current bios may well be ok. Worst case you’ll brick the NUC best case is you probably won’t notice any difference. Myself I’m a tinkerer by heart so I have the latest bios, which goes against the general advice of don’t update the bios unless you have an issue or it provides additional new hardware support that you require.
Geez…so many different choices to update the BIOS, that’s insane! I’ll likely just skip it.
ROON’s instructions should eliminate any directions explaining how to update the BIOS and just point a link to Intel’s website instead. Not that the average Joe will figure it out on their own, but there seems to be several methods to updating the Bios depending on what version NUC you have. Intel should explain it for the consumer, it’s not Roon’s responsibility to. Unless Roon is going to explain a step by step for each NUC, a partial attempt isn’t helpful. It just makes things more confusing.
If you can’t work out the keypress, or hit the moving target, then just remove the recovery bios jumper and make sure you’ve got nowt bar the .bio file on your USB stick. With everything else disconnected, power it on and the machine will do a recovery mode boot and bios update automagically. Intel Bios can be tricky coves sometimes, especially these new visual bios, not like the good old days when you could rely on a solid bit of OPSD engineering from the team in EP Hillsboro Good luck !!
