Hello everyone, I would be glad if you could help me modify the BIOS so that it would be possible to switch PCI-e slots between the first and the second. So, what would it be possible to use an old and a new video card.
Here my dump bios DropMeFiles – free one-click file sharing service
What do you mean by that “Switch”… What’s the issue using a GPU and the NVMe adapter?
It doesn’t detect the adapter in slot2 just on slot 1 or is this related to the GPU not being detected in slot 2?
I mean, in the settings there is only a choice between integrated and discrete video adapters, while I have two discrete ones. The second one will only work when I pull out the first one - the top one. I would like to have GPU1, GPU2 in the options to use specifically. No options like first or second. Only built-in or external.
I’m not aware of such mod or if possible, i also never saw that option in consumer bios settings to select slot 1 or 2 as primary. Consumer mb bioses will always assume an external GPU as primary device in slot1 x16 or iGPU or both, this i don’t recall to see a bios with such settings to another x16 slot, besides any standalone gpu can be the primary in any other slot.
I don’t know the compatibility chart of SLI/Crossfire of gpu card for this motherboard.
Where does the “NVMe” have to do with this… that seems you edited your post while i was answering…
EDIT: I see… out of my league and too much headache, sorry wait for another user pov, good luck
OK, I wrote here to clarify if modification is possible. I use the clover bootloader with a modified bios dump (DSDT). It disables the first slot and leaves the second one running. The system that boots with these settings sees the second one and works with it. Why do I need such settings? It’s just that there is no video driver for the card in the first slot for that system. I have multiboot computer (Windows, Linux, MacOS) running with multiple graphics cards.
I think if you open all the hidden settings, then there may be many interesting and useful options. Therefore, if it is not so easy to switch video cards, then I ask you to unlock the hidden settings.
Use IFR tool or AMIBCP as this is an AMI Aptio IV generation, it will show what strings are present and visible/not visible.
