My HP Pavilion, on the other hand, does not have a PCI Express x4 slot, but it does have a PCI Express x8 slot. According to the Hwinfo64 report of my HP Pavilion notebook, the graphics card NVIDIA GeForce GTX 1050 Ti (GP107M) sits in the PCI Express x8 slot. Specified for this graphics card is: x4.
Maximum Link Width:
16x
In the Hwinfo64 report of the board used for comparison, the graphics card is attached to the PCI Express x16 bus #1 (see below) as listed in the Bus section, i.e. in the correct place (16 lanes).

In the System Buses section of the SiSoft Sandra report of my Pavilion notebook (see below), there is a warning 1204 at the end. Possibly, the reference there to the higher maximum supported speed is due to the lower number of lanes (8 in the bus instead of 16).

Warning 1204: Speed is below the maximum supported speed. The device may be in power-saving mode.
Tip 3: Press Enter or double-click on a tip to find out more information.
If there is a possibility to disconnect the NVIDIA graphics card electrically, I could unscrew the notebook, do the disconnection and boot the Windows partition (In the default setting, another graphics card is active, after all). The hardware initialization should then assign the NVMe SSD to the correct port, since the NVIDIA graphics card is no longer present.
What could be the reason that the PCI Express x16 Bus is not listed by HWINFO in the BUS section of the HP notebook and why the NVIDIA Graphics card is assigned to the PCI Express x8 Bus of the HP notebook instead of the PCI Express x16 Bus?
Thank you very much.

Hi Bernd,
Can you please provide some more details on why you suspect this may be related to the EDK II open source content?
Thanks,
