Unfortunately no, but I have to start the windows vm that uses the rx480 before I can use atiflash for linux. Not sure whether I use the correct terminology, but it seems the bios of the gpu needs to be initialized/loaded before atiflash can access the gpu. If I try to use AtiWinFlash in the windows vm I get an Invalid rom error.

By the way, I spoke too soon about the PCIe Bus Errors. It looks that yesterday my syslog daemon froze and therefor I didnt see them anymore (oops ;). Today I got them again in plenty fold.

Cheers, Pim

    Follow-up on the issues I was experiencing, it looks like they are
    fixed by a new bios I got from MSI:

    <https://www.techpowerup.com/vgabios/188263/188263>

    With this bios my PCIe Bus Errors are gone and I don't need to
    specify the rom file in the xml anymore.

    Not sure if this is known to everyone, but I had some problems
    with the atiflash tool under linux as it did not recognise my
    RX480. It seems that this was because the RX480 rom's needs to be
    initialized before atiflash can access it. So in my case I needed
    to start my Windows virtual machine before atiflash recognised my
    card.

        Thanks for your comments, but it seems the MSI Gaming X series
        is not a reference card (its factory overclocked).

            So the vBios being bricked by the manufacturr should be
            also kept in mind.

        I dont think this is the case here, as using GPU-Z under
        Windows shows a valid EFI rom. It seems a Linux issue only, I
        have submitted a case with MSI to see what they say.

        Thanks, if I add the rom (the one I saved using GPU-Z under
        Windows) my display turns on.

        Unfortunately it didnt work then yet, as my dmesg was flooded
        with the following message:
        vfio-pci 0000:01:00.0: BAR 0: can't reserve [mem
        0xc0000000-0xcfffffff 64bit pref]

        This was caused due grub loading vesafb for the RX480 as the
        graphical terminal was enabled. So in /etc/default/grub I had
        to add GRUB_GFXPAYLOAD_LINUX="text" and disable 'GRUB_GFXMODE'
        (not sure about the last one as maybe thats implicit but it
        doesnt hurt either).

        Unfortunately that does mean I cant use ddccontrol it seems,
        as that complains about missing a framebuffer driver.
        Therefore I've also asked Asus whether they plan to support
        choosing the primary vga slot like Gigabyte does and they said
        'they will discuss this internally'.
        My Asus support agent actually had never heard of vfio before
        and repeatedly said that Asus only supports multiple GPU's
        when using SLI/Crossfire. So maybe if more people would
        contact their local Asus support agent and request this
        feature they are more willing to look at it? Who takes the
        hint? ;)

        I had to install the driver twice as the first time the
        install failed, but at the moment the GPU appears to be
        working correctly. Now first on to sound before I do some 3D
        testing.
