Hi!

I would like to enable SR-IOV on my MSI X470 Gaming Pro motherboard, but unfortunately the option to do this in the BIOS is hidden by default. I've understood that there are ways to un-hide this option by modding the BIOS. Is there anyone here who can help me on my way with that? I would really appreciate some pointers, thanks! The BIOS I'm currently using is the latest official beta, 7B79v1I5.

So it is not enabled on 1.2.0.5 for your board.

Under PCI setting
I don't have Click Bios lite screen shots

Thanks for your reply Alan. As you can see on my screenshot, for me the SR-IOV option is missing:

Thanks for the tip about the ticket system. I have raised a ticket, but I'm a bit sceptical that official MSI support will provide me with a modded BIOS? Well who knows!

Well, unfortunately I did not get a very useful reply from MSI:

Thanks for contacting MSI technical support.
Regarding your concern, sorry to say the motherboard BIOS doesn't have SR-IOV option. Thanks!
Thanks for your cooperation in advance!
Best Regards,
MSI Technical Support Team


Doesn't look like they're going to give me a modified version of the BIOS, unfortunately, so I'll have to get it some other way.... but how?

Well it would cost them a far bit of money to mod a BIOS as it would need testing but more that ask more the chance of it happening

And there may be more BIOS updates to be released yet

There is a bios mod section on this forum and bioses can be obtained for a "donation"....

This is what @Svet does on the forum, bios mods. I don't know what the acceptance criteria is however.

Thanks Laurence. Actually I posted this thread in the modding section, but it was moved by the moderators to the AMD Boards section.

@Alan J T can you please move this thread to the modding section? Thanks! It would be great if @Svet can help me with this...

Someone else had the same problem, but I don't think they stuck around long enough to see the reply from svet.

Update

I managed to get my hands on AMIBCP, and tried to edit the entry for SR-IOV so it would be USER visible, like so:

Flashed the modded BIOS. Didn't help.

Then I opened the BIOS image with UEFITool. Did a search for any strings containing "SR-IOV" and "AMD CBS", and extracted the corresponding PE32 image sections by using the "Extract as is" option. Then I made these human-readable with Universal IFR Extractor, and opened them with Notepad++

I was hoping to find some clear indicator in these sections on why the SR-IOV option is hidden/masked/whatever, but unfortunately I did not. I don't really know how to proceed...

I have not done any BIOS modding part from boot logo in a Very long time last time was way back when bios was less than 1mb in size
Ya I would not know what strings to adjust from what you have there but looks like you need to do several to get it to show up and be selectable.
