ALL QNAP BIOS does not work on all systems , you need to slow down here or you will have brick device.
Only use BIOS from your exact model, if you do not find one for your exact model that supports IVY, then your done looking, you can't just grab random QNAP BIOS for other models and use ANYTHING from it into your BIOS, this is now how BIOS work.
I cannot understand your microcode questions or concerns, but they are not really relevant, if you want updated microcode I can do that for you on your original BIOS.

Thanks Fernando :) @SoniX could you confirm whereas the UBU 1.78 does not have the limitation of two microcodes reported by @elisw at post no3 of thread Coffee Lake CPUs on Skylake and Kaby Lake motherboards ?
=======================
I do not think that this is possible, as the chipsets on each NAS system are different. Only the CPU socket 1155 are the same and maybe some SATA and LAN cards? Is there something that I am missing?

Please use edit button if you need to add more questions, or thoughts etc and no one has replied yet, thanks!
And yes, there is a LOT you are missing and or do not understand here, best to just use best CPU your model supports, or upgrade to something better

:D I was in full throttle until yesterday and had plenty of luck as I flashed few modded bios but no luck. Will take your advice. Yes I would appreciate any help. This is my hobby, as real profession is MD.

Apologies for questions that seem irrelevant or not cohesive. I understood from reading the various guides here that one can do patch work in BIOS from other similar/compatible bios.

I have uploaded the original latest bios of my device the QA61AR22 and also the QV84AR06 of another NAS which supports Ivy bridge CPU. Both NAS motherboards are relatively same on configuration of ports (HDMI, 2xLAN 2x e-SATA and 4 USB) but have different chipset. Mine the C206 and the other the H-61.

Ok will start editing instead of new posts

No need to apologize, I was only trying to get you to slow down before you brick your system
In certain cases, sometimes yes, you may be able to use something from one BIOS to another, but that is limited to certain things in certain situations and you have to know what it is you're doing and how to do properly etc.
Those two systems you mentioned are not related at all, different chipset means different board etc, nothing same and BIOS contents totally different (connection ports do not matter to what we're talking about here)

Requesting IVY BIOS from QNAP is your best bet here, if they will not provide one then you will probably have to make due with whatever is best CPU you can find that is compatible with this BIOS as it is.
