    Korábban írtam, hogy sajnos nincs meg az eredeti bios fájl :( Ez egy probléma. Van rá megoldás? Vagy dobjam ki az alaplapot? :(

    I wrote earlier that unfortunately I don't have the original bios file :( This is a problem. Is there a solution? Or discard the motherboard? :(

    The machine was not disassembled, bios chip around all the parts in place and I found no problem. Is there another option? other component does not accept the new bios file?

    CH341 is a cheaper programmer and time to time have problems to read/ write bios chip

    did you unsolder chip from motherboard and write it?
    di you verify it after programming?
