    in BIOS & Schematic Requests!
    Hi peste,

    Here is the requested information:

    Serial Number (S/N): A8A1699EC0B8

    Full model name: ASRock Z590-C/ac (Link)

    BIOS chip: MX25L12872F (16 MB / 128 Mbit)

    Attached is a full 16 MB raw SPI read taken with a CH341A from my BIOS chip
    (filename: Contents_BIOS_Chip_(1.30).bin.zip).
    This is the current contents of the chip, The ZIP is ~9 MB, but the extracted BIN is exactly 16,777,216 bytes (16,384 KB).

    Thank you for your help....
