Hello. Here is your bios.
I checked everything. Everything looks good.
If this BIOS does not solve the problem (and I checked everything is fine in the BIOS), then it’s definitely not the OpROM, but:
- In the individual settings in the BIOS;
- Hardware incompatibility.
I want to share about a problem that I had and I think you have the same problem.
I have an old GIGABYTE GA-EP45-DS3P motherboard, it has 3 pci express 2.0 slots (first slot works x16, second x8, third x4). This board has ATI CrossFireX technology. When a video card is connected to the first slot and all other slots are empty, the video card works in x16 mode. When there is a video card in the first slot and you connect a second video card to the second slot, my chipset divides the pci express slot like this:
pci express 1x8
pci express 2 x8
This is the problem. Nvme uses x4. When these boards were created, there were no nvme and when you connect to the second pci express nvme, the chipset “thinks” that you connected the second video card and sends 8 pci express lines. My computer refused to “see” nvme. (Although if you connect a dual nvme adapter with two disks to the second slot, the computer will see it, but only the first disk will work, since there are no settings in the BIOS for dividing x8 by x4 + x4).
You, in the characteristics of the motherboard, also have pci express division, this may be the problem.
As always, I warn you of responsibility that I do not bear any responsibility for updating your BIOS, possible problems during operation and updating. If you are not confident in your abilities, you need to refuse to update the BIOS.
