    I receive my M4000M and it is not new, it is already used.

    To plug it in my m18xR2, i had to :
    - take back the x-bracket from one of my 7970m (it was glued, so not as easy as i thought)
    - take back the black strip from the heatsink and remove all the glue

    On the first boot (in PEG, not SG), Ubuntu boot, and M4000M was detected.

    I am on A11 unlocked bios, and i wanted to try to enable legacy rom in boot options, and now, I have 8 beeps (not 7) and no boot screen, so I can go into bios anymore :(

    Just because i set legacy rom from enabled to disabled ?
    I saw previously that disable legacy rom create some visual glitch on bios screen, that's why I used to enable it.

    I tried to reset CMOS by unplugging adapter and battery and push power button for 30 sec, but still no boot..

    Any idea ? Everything was working fine on the first boot, no artifact, no freeze... I rebooted a few times and I had absolutely no problem, until I change the legacy option, and just after that, no boot anymore.

    Edit : I will try the advanced reset cmos :
    Disconnect AC adapter
    Remove system battery
    Remove bottom cover
    Disconnect CMOS (coin cell) battery
    Ptess power button 30 seconds
    Reconnect CMOS battery
    Connect AC adapter
    Power on - if you get 5 beeps, don't panic... This is common. Power off and on again and you should be fine.
    F2 to enter BIOS. Set date/time, any custom settings (be sure to leave Non-Turbo Flex Support "Disabled")
    F10 to save and exit setup
    Power off
    Reinstall bottom cover and battery

    Edit 2 : CMOS reset worked, so i put it in SG + legacy, and it boots normaly.

    Edit 3 : I only had to uninstall mesa-vulkan-drivers on ubuntu used for amd gpu, but after that, I can say that it's almost plug & play. And this confirms that my m18xR2 MB is ok, it was really both 7970m that were bad.

    Thank you for all your advices. Maybe I will buy a keyboard someday, but not at 100$, and I don't find cheaper, even in QWERTY.

    For the keyboard just keep an eye out as it is not unique to this machine and several others used it as well M17X R1 on through to the R4. I wouldn't pay $100 but sometimes one can get lucky.
