    well bro ... i tried that it went back to the same boot manager screen.

    when i reset the bios by removing the battery it went back to legacy mode it seems as my windows installation done in uefi was not being read ... i even flashed the stock A12 bios .... i think ill have to download your bios again and flash that and hope for the best ...

    thanks for the support ill keep you posted may not get the time ... today

    When you revert back to Legacy mode, you will have to reinstall your OS, as you did install Windows in UEFI mode.

    Nvidia System Tools is not working right on windows 10, at least on my sons l502x.
    For MSI Afterburner i need to give him a admin password. Poor solution.
    I wanted to underclock on bios level and dont use any other software in OS.

    i found temporary solution with app "RunAsTool" now msi afterburner is working in standard user account

    thanks

    Hi @Thiblizz ... I've been seeing new commits to your Dell XPS BIOS repository recently but no updates in the changelog... Just asking to know if there's some new changes... Thanks...

    I've just updated iPXE and modifying dumps, as I don't want to push other commits (want to keep v1.0.0).

    I'm doing a lot of tests on the dump right now.

    This is all related to my coreboot port, I almost brick my laptop again...
    I have only Linux, and over 5+ USB keys with devs tool and WinPE build to work on the BIOS, as I have reprogrammed my BIOS chip externally with my freedom dump, now I can directly reprogram it on FPT (I did not test flashrom yet).

    The problem was that while reprogramming, I got BSOD on FPT (before it start to write the chip xD), hopefully that did not brick my laptop, so I have used it on FreeDOS and now it's working well.

    Everything on my GitHub is stable and fully tested.

    So can we install the latest update? Or we should wait a while?

    Sure you can use everything (as I said GitHub is stable branch only).

    Ookaaay, @dedos ... I guess you'll probably need to underclock then.. Try reducing your core(/memory) clock speeds till the crashes are drastically reduced... I'm currently running at Core: 522MHz/ Memory: 700MHz on my 540M with very low chances of having crashes (like twice/thrice in an average gaming day)... My laptop charger got damaged yesterday... I'll have to purchase a new one... This time, I'll go for the 130-watts... Has anyone confirmed using the 165-watts charger without crashes?
