    Thank you LatinMcG for your response
    I placed 363CF1D.bin file into formatted fat32 flash and renamed the file to 363C.bin
    Fn+Esc does not do anything the laptop just start normally, but pressing Windows+B the laptop tries to run something from usb for like 5 to 10 seconds then it start with no change. should I go for the second method?
    can you guide me please?

    I tried to identify the chip, it's very hard what I can read is (winbond 25x40a)
    I already ordered CH341A 24 25 Series does it work for my chip and what are the steps to use this programmer?

    Best regards

    I am trying to read from (winbond 25x40a) chip but with ch341a 1.3 version program it gives me an error while trying to detect chip : (Access violation at address 0097EA42. Read of address 0097EA42)

    Trying other versions it does not detect and when I select chip manually and try to read it just give me all FFFF
    what should I do???LatinMcG please help.

    First thing I tried to program (winbond 25x40a) chip while it is soldered as I thought it is the bios chip, I had backuped the data after several tries with various programs then I erased and tried to write the bios to the chip and I think that I did that wrong because I do it while the chip vis soldered to the board.
    After that, I figured the other chip the (WINBOND 25X16AVSIG) when I read it I have data similar to the original bios so I know that what I done with the other chip is wrong.
    I desoldered the (winbond 25x40a) and write the backup file that I made at the beginning, then I sodered it again and desoldered the (WINBOND 25X16AVSIG) and write the original bios, after resoldering the chip I tried to run the board but it does nothing, it's bricked.
    I tried to restore everything to original status but no response.
    The (winbond 25x40a) gives voltage reading when the motherboard is connected to a power source even without clicking the power button, while the bios chip shows no voltage either with or without pressing the power button.

    I think that when I tried to write to the ship while it is soldered it interfered with other chip.
    is that right?is there any solution?
