I have a Acer Predator PO3-620 , Version 1.0 American Megatrends Inc., Version R01-A1 BIOS dated: Mon 13 Jul 2020 12:00:00 AM CEST Intel® Core™ i7-10700F CPU @ 2.90GHz The mainboard has 1 pcie 4.0 x16 and 1 full m.2 and 1 small m.2 (where a useless wifi adapter is currently sitting). I have a cheap graphics card that needs to be plugged into the mainboard pcie slot, otherwise the pc won't start (since the cpu has no onboard graphics). The problem is: I want to install a pcie x4 10GBE Network card into the pcie slot and don't need the graphics card. Is it possible to deactivate the check for GPU in the Bios? I didn't see any option for that. Another idea would be a x16 to 2 x8 splitter and use the gpu with half the lanes and the network card at the same time, but I didn't find an adapter for that. (Only ones which split to multiple m2 or sata or usb ports) Is there anything I oversee or what I can do to start the server and have 10GBE ?
