Crashman :
Gigabyte occasionally released a firmware update that modified the detection scheme so that BIOS downgrade is less likely to happen on past products. As you've indicated, they haven't fixed every board and the fix doesn't work for every configuration.
Gigabyte also has true dual-BIOS motherboards at the high-end, where the forced downgrade can be disabled. You've probably just missed that little tidbit if you think all Gigabyte boards are like this one.
This is the worst board Gigabyte has sent in a long time, and the first one that I've had to recommend against buying. It's been a few years since I've had a Gigabyte board fail after continuous forced-downgrades.
Gigabyte obviously doesn't like that we told you any of this. But to not tell you would be to lie. Its PR are nice people, but I can't lie for them, so it looks like they'll probably pack up their toys and go home.
Gigabyte PR people might be nice people, but there's only so much one can do about pumping up poor hardware design.
I've had four Gigabyte motherboards, and I've had hardware compatibility issues with them all. I've had bios issues with three, where I've needed a new bios to support a new generation of processors, but the new version doesn't work well. The latest one was my x79-UP4 board, where it didn't like my EVGA GTX 680 with the F2 bios, and the F4 bios caused the screen saver and power saver features to never turn on, and it took their support nearly two weeks to get me a program that would allow back dating the bios to the F3, which finally worked. The audio plugs never detected when speakers were plugged in, so I couldn't use the on-board audio. Finally, after 9 months of annoyances, it stopped giving power to the USB ports and the PCIe x1 slots, so I lost access to pretty much everything. It was a slow, horrible death for a bad motherboard. I'm not buying a Gigabyte product again.
They don't need PR. They need to get their heads on straight and engineer their boards better, and test better. Testing is a basic necessity for any technology design. I am a systems admin for three test labs for enterprise level hardware and software. I have seen how many bugs we find and exterminate through our testing, and I have seen how it has affected the quality of our products as management decided to reduce the complexity of our testing. Above all, I have seen how it has affected our sales. Gigabyte has never been very good at their testing. If they want to compete, they need to get off their high horse and confront the criticisms for what they are: a chance to change. If they're pulling their products from being reviewed on this site because of these criticisms, then they have shown their attitude, and nobody should be buying from them anyway.
The response from APC on the power strip teardown shows how a successful company reacts to criticism. Gigabyte's reaction will show if they're up to the task of staying in business.
