I updated my X79-UP4 to the latest official F4 BIOS (using the @BIOS software, as advised).
A few questions/queries:
The 'full screen logo show' is enabled, but never appears during POST, it appears the video card is enabled last now so the screen stays off until the AMI BIOS flashes for a second just before Windows starts to boot. I never see the Gigabyte logo
Where has '3D BIOS' gone? All I can get now is Advanced mode, the 3D mode that was working with F2/F3p is no longer available. Pressing F1 doesn't switch to the GUI 3D BIOS anymore.
The option to switch 'UEFI' to 'Legacy ROM' is no longer available. Not a problem as all seems to work ok but if needed how can I enable Legacy ROM?
The new options for 'SATA Hot Plug' - I had to Enable the SATA ports I wanted for this, otherwise my external drives wouldn't be found after Windows boot.
