Thanks for posting this, very interesting and surprising. I mean the sensor readings and the parallel port.
I don't think it is normal for the sensor readings to not work with that port disabled. I normally do that on all my ASRock boards, disable that port, and I still get all my sensor readings. I will check to make sure that is true with my ASRock Z270 board and post back in this thread.
About the Ultra Fast Boot setting of the Fast Boot option. We can use the Ultra Fast boot setting ONLY if several things are ALL TRUE about our PC and Windows installation:
You must be using Windows 8, 8.1, or 10.
You must have installed Windows for UEFI booting. That means you installed Windows with the CSM option set to Disabled. You must keep the CSM option disabled at all times. Your Windows drive will be formatted in GPT format, not MBR. The Windows installation will use the EFI boot loader, not the Legacy boot loader.
The Windows installation media shown in the boot order must have this format: "UEFI: <device name>". If you did not select that entry in the boot order, you will not have a UEFI booting Windows installation.
Your video source (graphics card or iGPU) must the GOP compatible. GOP is a UEFI video protocol that MUST be supported by the VBIOS of your video card. All EVGA video cards since the Nvidia 700 series are GOP compatible when you buy them. For other video card manufactures, I don't know, you must check with the manufacture. The Intel iGPU has had a GOP compatible VBIOS for many years.
Some of this information was shown in the description field in the BIOS for the Fast Boot option.
If your PC does not meet ALL of these requirements, you cannot use the Ultra Fast Boot setting. It will do exactly what you described, no video to the screen.
But you are also telling me, that setting that port to enabled, you can use the Ultra Fast boot option?
