An 8 MB BIOS dump for the Acer One 14 Z422, with NH4CZ0X appearing as a model or part identifier in the name. The name gives no board number, ME status or version, so treat it as a raw full-chip image. It is written to a 64 Mbit SPI flash chip with a hardware programmer when a laptop fails to boot from corrupted firmware. Save the existing contents before erasing, verify the chip capacity is 8 MB, and where possible compare the board markings with a known source.
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 @vinafix_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 →
