I put them in the machine, in a x16 PCI-e slot. It would work fine, Windows sees it, the Win installer sees it, I can even create a drive letter, but I can’t set it to boot from this device in the BIOS (normal). A mod BIOS was created for the v1.0 version of this motherboard, maybe there is one for v2.0 as well. There is a very long description on how to somehow push this in to make it work, but unfortunately I got stuck at this chapter. This is a live machine, I don’t want to ruin it, because then I really have to buy a new one. I have also seen screenshots of the v1.0 version, where the list of bootable devices in the bios included PCI-e x1, separate x4, separate x8, and finally separate x16. I don’t know, I’m not familiar with it, but it is visible, so it can be written to the Bios. By the way, if anyone has such a file, please share it! I heard afterwards that this cannot be put in the q-flash menu on the motherboard. I would also like to know how I can make it work. Thank you in advance for your help! I came across several dead links in another topic, not a modern motherboard, but it still works. Thx!
