Booting from pci express lane


Doe's anyone know which generation of motherboards allowed booting using a Windows drive fitted to pci express? I think my motherboards may be too old as there is no mention of this in the manuals.

 

PCI express on windows

I have tested 15 different PCI-Express display cards on a i3 Gigabyte/intel motherboard with windows 7/8/10 . Windows 7 is the last windows that was capable to handle two or more displays. from windows 8 upwards windows are unable to handle pci-express
displays no matter if you have the correct drivers from the manufactory. You will be having blinking, black, flickering screens. If you are a gamer rather look at other operating systems like apple Windows are not a gaming operating system anymore there are
NO updates or solutions to force your pci express to operate on a windows 8/10 platform. Only your onboard standard display will function correctly sadly giving up some of your ram used by the onboard display and keep in mind only older lower 3d games will
operate
