    The only "right now" is for you to try to explain it in a way that one could understand what you want!

    Winbond W25Q32 is 32mbit chip.... so cut BIOS should be 32/8 = 4MB size (4096KB)....

    Its very low possibility that BIOS flash could kill screen and webcam... seems like there are HW probs ;)

    What are you talking about 'my file has killed the screen and webcam????o_O

    That is wrong. I have changed no single bit of the EFI. A bad SPI flash NEVER causes hardware damage, one just needs to reprogram the chip again.
    I did it this way a lot of times before to just to cut the padding which is NO bioscode. It EVER worked.

    So I would be careful when stating unproved assumptions, especially when you try to say that something has happened to you that never happened before at all!!!
    This is no modified BIOS AND a bad SPI flash NEVER causes hardware damage. A wrong bios image and sloppy (de)soldering can, though.



    "i've found a resistor unplugued from the motherboard"

    Haha lol!!! This is not its normal state isn't it? lol.

    And who screws the hardware? Come on!
    It is more than probable that you did a mistake when soldering, or have chosen the wrong biosfile, or damaged your own board!
    I am experienced enough to admit a own fault IF I had made one....but this seems laughable.
    You might read success threads here using the same method. ;)

    You flash wrong eeprom! W25Q32 is VBIOS, BIOs chipset is on the other side of MB, near super I/O, should be 25X40
