    Edit:
    I found IntelMEv7.1.60.1193.zip and Intel ME Firmware v7.1.80.1214 (1.5MB).rar
    Found L502X_A12_540m_83_85_Unlocked_Menus_v6.rar and L502X_A12_540m_83_85_Unlocked_Menus_v7_beta.rar, also earlier versions made by capitankasar
    /Edit

    Just looked into this thread for the first time since some years. I think I found it. I used the 0.83/0.85 profile with the 540m, too.

    Can I send you an email?

    I found this on Github: https://github.com/mobilexp/l502x-modded-bios
    I suspect he changed his github username or didn't like that Microsoft took Github over.

    Hi,
    i am new here and tried to find a way to contact the great programmers.
    I am looking for the latest modded BIOS for the L502x with M540 graphic.
    For me gaming isn´t important at all. I´m only looking for the mod with extented settings and resistant against Spectre and Meltdown.
    Can somebody provide the latest BIOS?
    I read about Intel ME Firmware - and found Intel ME Firmware v7.1.80.1214 (1.5MB) and Intel ME Firmware v8.1.70.1590 (1.5MB) - but i have no idea if this helps somehow or how to handle it.
    My both machines now run under Win10 64 (AHCI) and have BIOS A12.

    Greetings from germany
    Werner

    There are like 6 different variants of the BIOS. You'll have to read through the thread to find which version is best for you. The different variants are based on what hardware you have installed.

    I am looking for the extended stock BIOS including the latest Intel ME Firmware for the L502x with M540 graphic.
    Which one is best to use and where can i get it?
    I saw Dexter1983 updates Thiblizz´s BIOS with Intel ME 2f-version - but can´t find any download for that.
    Which is better - Capitankasar´s BIOS or Thiblizz´s ? As far as i understand Thiblizz´s base on Capitankasar´s, right?
    If it is Capitankasar´s BIOS i would like the "Non voltage moded A12 bios mod with advanced menus for L502X".
    Can somebody explain how to add the latest Intel ME into the BIOS?

    Many thanks to Capitan Kasar, your custom bios stabilised my newly purchased Dell XPS 15 L502X i7-2670QM GT540M. I was not able to start most of my favourite old driving games, and the system was freezing in the rest that I was able to start.
    I already own a Dell XPS 17 L702X with same configuration (GT550M video card) and I've never encountered any of the above problems.

    Apart from expressing my gratitude, I am posting as I have found it very difficult at the end of 2020 to find the files, given the age of the post with most links not working anymore. Starting with the modified bios file, the Intel ME Firmware file and the correct fwupdlcl (that is the Intel Management Engine Firmware Update Utility), combined with extra reading to make sure I am not messing something up, it took me a couple of days to crop everything together and end up with a stable laptop able to even support overclock on the GT540M.

    My system came with the A12 bios from Dell.
    Intel ME Version: 7.0.4.1197 (7.0, Build 1197, Hot Fix 4).


    1. I have installed L502X_A12_540m_83_85_Unlocked_Menus_v6.rar (the recommended version for L502X with GT540M):

    Custom voltage moded A12 bios mod for gt540m with advanced menus for L502X

    DOWNLOAD from Mediafire - download link: http://www.mediafire.com/file/vbj6k2fm7ree2a6/L502X_A12_540m_83_85_Unlocked_Menus_v6.rar/file#
    MD5 checksum A0DAB7E7FB91BA9E2CD64C3E76D048F3
    mod version version 6
    BIOS version used A12
    this bios mod has been tested by guessyet
    2D PROFILE 0.83v
    3D PROFILE 0.85v
    notes Voltage modded A12 BIOS for gt540m with a nice set of extra options,plus native speedstep and updated CPU microcode,intel vbios update to v2137, sleep FIX for OSX,computrace unlock ,serial tag changer and RAID, handle the new options carefully!Recomended for GT540M users!
    Everything needed for the bios flash is contained within the .rar archive.

    2. To update latest Intel ME Firmware, which for the 1.5MB version 7 is v7.1.80.1214 (1.5MB), you need the 7.1.80.1214_1.5MB_PRD_UPD.bin file contained in a .rar archive Intel ME Firmware v7.1.80.1214 (1.5MB).rar (I have found a LOT of information and the link to the latests IME firmwares on the Win-Raid Forum link https://www.win-raid.com/t596f39-Intel-Management-Engine-Drivers-Firmware-amp-System-Tools.html) and the right version of the Intel Management Engine Firmware Update Utility (fwupdlcl 7.1.50.1166):

    Intel ME firmware update v7.1.80.1214 (23/07/2013)
    Intel ME 7 1.5MB Firmware v7.1.80.1214
    For 6/X79/C600-series systems which run ME 1.5MB v7

    I hope this helps other users with Dell XPS 15 L502X GT540M.
    Remember to keep all programs closed when doing the bios and the firmware updates and that your batter is charged and the laptop plugged in to avoid surprises in the middle of the flashing procedure.

    Upon my research, I've noted that other laptop manufacturers have included the latest Intel ME Firmware in their BIOS updates. Clearly Dell didn't care enough for their customers to be arsed to do the same, hence going through the hoops.

    As others posted, I don't assume responsibility if things don't go smooth in your case, this is meant as a help with the links and as a case report where everything went sweet and smooth. You do changes of your own choice and if things go wrong, you could end up with a bricked laptop.

    Other notes I would like to make about the Dell XPS 15 L502X i7-2670QM GT540.

    The mainboard chipset is North Bridge: Intel Sandy Bridge-MB IMC/ South Bridge: Intel Cougar Point HM67 supporting Dual DDR3 PC3-10600 DDR3-1333 memory. The motherboard's chipset supports four slots, of which only two are installed in the GT540M version of the laptop. Dell claims the laptop supports max 4GB of RAM (2x 4GB Dual DDR3 PC3-10600 DDR3-1333 memory). This I found not to be true.

    I have tried the following memories with no restrictions as to running frequency:
    - QUMOX 16GB(2x 8GB) DDR3 1600MHz PC3-12800 (204 PIN) SO-DIMM MEMORY - it ran at 1600MHz and I have found confirmation online that the L502X is capable of running memories at both 1333MHz and 1600MHz
    - Kingston HyperX Impact HX321LS11IB2K2/16 Black 16GB (8GB x2) DDR3L 2133Mhz PC3-17000 Non ECC Memory RAM SODIMM - it ran at 2133 MHz.

    With the custom bios from Capitan Kasar you can lock these memories at lower frequencies in favour of lower latencies, but I think that this would decrease overall performance of the system.

    I am now waiting for updated links to the unlocked BIOS for the L702X. I own the L702X for some years now and I never knew I needed an unlocked BIOS until now.
