Firmware dump for an Esonic motherboard identified as HM65MCL2, stored in a 2.45 MB RAR archive. The name gives no revision, BIOS version or flash chip details, so the board model is the only identifier to check. Images like this restore a corrupted SPI BIOS with a programmer such as a CH341A, usually after the chip is desoldered or reached with a test clip. Check that the model printed on the PCB matches exactly, back up the existing contents, and confirm the image size equals the chip capacity before you program it.
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 @biosarchive. Enginerys does not host this file.
