Gigabyte fixed BULLSHIT.
The Firmware-Downgrade-Bug is present since P55 boards and I saw it on EVERY generation, be it 50, 60, 70, 80 or 90 series boards. Not necesserilly on every version of the chipset, e.g. I saw it on a P65 but not on a G61 chipset. But if you have the bug then rest assured they will NEVER fix it.
The P65 was especially nasty, it downgraded the bios even when actually nothing went wrong and all BIOS settings were "default". EG I once pressed Reset and voila, back to F3. Also happens if I disconnect from power, even if the system is actually already shut down. Only way to avoid this is to power down the system safely by the OS. But then you have to switch the system on at least every couple of days or it will downgrade to F3 immediatly after power on.
Gigabyte? No thanks.
