Raw 4 MB BIOS image labelled zx-h61cm version 1.31, apparently for a desktop board based on the Intel H61 chipset; the name gives no brand. A 4 MB file corresponds to a 32 Mbit SPI flash chip, typical of H61 boards. Technicians write such a dump with a programmer like a CH341A to revive a board that powers on without POST. Verify the board model printed on the PCB and the chip capacity before flashing, and read the original contents first so you can restore them if this image proves unsuitable.
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 @biosdumpcomputer. 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 →
