    Unfortunately, I have the same problem as @Guillome (in this thread) and @Floww (in this thread).

    I can't PM @Prema

    So please Prema, can you send me the fixed BIOS so that I can update the BIOS of my Clevo W550EU?

    Thanks a lot!

    Prema if you see this do you have a bios for the 650hs-g model by chance? And if so, could you be so gracious and pm me so I can donate funds for your awesome bios mod? Do you by chance do EC bios’s as well?

    Hello @Prema , I've working on coffee-lake mod for old series laptops months.
    But I still have some bug cannot fix by myself.

    1.MSI 16L1 , 16L3
    Port BIOS from MSI G25 , change pch-io configuration (both in BIOS and ME)to have all pcie work.
    Modify dsdt to have battery , ac power , keyboard , touchpad working.
    But USB and Graphic work abnormal.
    16L3 has the same audio problem like DM series.
    Modify on original BIOS , only works with coffee-lake CPUs less than 8 thread.

    2.Clevo P7xxDM2,3/P870DM2,3/P870KM
    Port BIOS from P7xxTM or P870TM , change pch-io configuration (both in BIOS and ME) to have everything work.
    Modify NVdGpuPei to have old DM Edition GTX1080 works with P870TM based BIOS.
    But all these laptop with 10-series graphic card need oc vbios , or they will not boot.
    Modify on original BIOS , only works with coffee-lake CPUs less than 8 thread.

    3.Clevo P7xxDM
    The same as DM2,3 , and have audio issues ( audio jack mismatching)that I cannot fix.
    I replace all EC 10 99 08 to EC 10 92 08 in UEFI Modules , got subsys id of realtek audio change from 10ec0892 to 77091558 , but audio jack still mismatch.
    I edit driver inf , exchange 77(5)091558 and 77(5)021558 , but nothing happen.
    And cannot power off when ac connected . It will auto-reboot after shutdown windows.

    4.Clevo P870DM
    The same as P7xxDM , only difference is P870DM do not have power off problem.
    It has power on problem.
    Sometimes cannot boot OS , stuck in "Resume from Hibernation...".But I didn't hibernate it , I just shutdown windows normally.

    5.Clevo W650Kx/W650Dx N650DU
    Cannot port BIOS from NB50Tx , it won't boot.
    Modify on original BIOS , only works with coffee-lake CPUs less than 8 thread.
    Port from W650KL , discrete graphic doesn't work.
    N650DU has no discrete graphic so works fine.

    6.Clevo W650KL
    Seems it's a Z370-like BIOS , so everything works fine.

    7.Clevo N95xKP6
    Port from N95xTP6 , everything works fine.

    8.MSI G65
    Port from G25 , have one strange problem.
    When I use USB mouse and keyboard at the same time .
    Press A-Z or space , the left mouse button not work.
    Modify on original BIOS , only works with coffee-lake CPUs less than 8 thread.

    Honestly asking for solution to these problems or better method for coffee-lake mod than port Z370 BIOS to old PCH.

    Hello everyone,
    I have a P150EM, that I in bought in 2012. It had the nvidia gtx 675m graphics card, but the same died this week.
    So I need to do a replacement, but It is more easy and almost the same price to buy a gtx 970m.
    I wold like to ask about the Bios and vBios I need use to get a better performance.

    Some data about my laptop:
    KBC / EC Version: 1.02.11;
    Bios Version: 1.02.17;
    I intend to use only two sticks of 8gb memory;
    I have the 180W PSU

    Thanks.

    Hi, @Prema.

    Is it possible to get a BIOS for Clevo W355SS? My old motherboard died and I'd like to change the BIOS for the new one I got.

    Thanks! :)
