Small 1 MB firmware dump from location U22 on the Quanta DA0QU5MB8C0 board of the A520 all-in-one, revision A1, which carries an NVIDIA N13M-GE2 GPU. A chip this size beside a separate 8 MB BIOS image usually holds controller or auxiliary firmware, so it should go only to the matching U22 device. Write it with an external SPI programmer after backing up the original contents. Confirm the board revision and the capacity of the installed chip, since an image that does not match the flash size will fail.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @abgm_manutencao_bios. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
