    win 8.1 if you're using a 120hz panel then you have no choice but to use only win 8.1 if you're on the older AW17 models.

    Well if legacy boot does indeed work with the new vBIOS, why wouldn't you go back to windows 7?

    I guess it's risky for you 120Hz guys, since you have no iGPU to fall back on in case it doesn't work but.....no guts, no glory ;)

    display output should still work in the bios, if not in windows, thats all youd need ;) either that or an external display :)

    I tried going back to legacy mode, and was surprised that I didn't get the 8 beeps of death. What I did get was:


    "Check cable connection
    PXE-MPF: existing Intel PXE Rom
    No boot device found. Press any key....."


    What this tells me is that I would have to switch my GPT formatted ssd HD (it has the OS on it) back to MBR. See, this site concerning legacy bios incompatibility with GPT http://www.rodsbooks.com/gdisk/bios.html . This would require wiping the drive and reformatting it to MBR and reinstalling the OS. I have no intention of doing all that, my system works great and that's good enough. But, if some one wanted to use legacy mode with the 980s it seems it can be done.

    YES! Great news! That means the 980M has proper legacy boot code implemented. That message you got is indeed from MBR/GPT mismatch for BIOS type (Legacy/UEFI) due to the way the bootsec is handled by each system/format. The important test is being able to access the BIOS and seeing nvidia GFX in the info menu while being in legacy mode!

    We need a M18x R2 user to test!

    NO, don't try that on M18xR2... ;)
    That's again due to the new BIOS and not vBIOS (scanner didn't even use the new Dell vBIOS, he's on my vBIOS Mod).

    Whoops, sorry I've been using @Prema vbios so long I forget they're not my originals.
