"We no longer have the motherboard-specific BIOS source code, build environment, and tools to build new BIOS releases with the microcode update for some discontinued products."
That is ridicolous. I mean, the point is, they don't have to rebuild a Saturn V rocket. It's a BIOS update.
Give us the undecrypted version, not the BIO file, and we can do it on our own.
"I think going back nine years for most of these boards is pretty good. If your board is older than that, I would upgrade."
My board isn't older and still powerful (3960x), but I think, my next CPU won't be an Intel. Sorry, but too many fails at once.
Intel exited the Desktop Boards business over five years ago. The team that worked on these boards is long gone. That Intel assigned a team to do what they could to cover these boards is admirable. They didn't have to. It's a shame that some boards could not be covered but, when a business is shut down, this kind of thing is going to happen. If it was a separate company shutting down, no one would be getting anything.
As for your comments regarding BIOS and updates, you obviously don't have a clue what you are talking about. Regarding a "decrypted" version, there simply isn't one to give (if there was, then they would have what they need to build a new one). Regardless, Intel would never, ever ship firmware in this form; that just creates yet other security issues.
I worked for Intel for 21 years (I am retired now). Intel was the most honorable and ethical company that I ever worked for. In this case, they were honest and forthcoming right from the gitgo and a lot of people have worked their tails off to deliver fixes in a timely fashion. I cannot say the same about the competition; all they did was deny, deny, deny. Well, look at the vulnerabilities that have been reported in their products in the past few weeks. Same processor issues, same management engine issues, etc. As for motherboards, most of the far east manufacturers don't give a d@mn about boards once they ship and few people will be seeing BIOS updates. Still, if you want to go off and use their processors and boards, go right ahead. When you find out that the grass isn't greener on the other side, don't come crying back here.
