    Lenovo Legion Y540-15IRH - need BIOS or help with DMI

    Laptop - Lenovo Legion Y540-15IRH 81SX
    MB - NM-C221 Rev: 2.0
    CPU - SRG1T (i7-9750HF)
    PCH - SR40B

    I don't have original bios dump from this laptop. Somebody tried to repair it and left it with non-working bios.
    I repaired this MB and tried bios dumps from this forum, and some of them work, but there's no DMI data in bios (Product name, MTM, Lenovo SN)

    I ask for some dumps to try out or help with adding DMI manualy (I do have a sticker with DMI info)

      Thank you for reply.

      I tried that tool on this laptop before.
      I followed the instructions but i get "Init. SMBIOS ERROR" whenever i try to write or read something with amidedos on this motherboard. amidedos works fine, because it returns commands that i can use with it.

      Have you sucesfully used this tool on this motherboard? If so, I might be doing something wrong
