BIOS image for the ECS H61H2-M2 desktop motherboard at revision 1.0, with ECS-15-Y90-011003 appearing to be the board's part number. Judging by the name, the board uses Intel's H61 chipset. The archive is small at 168 KB, so check that it holds a complete image before relying on it. Use it to reprogram the BIOS chip with an external programmer when the board will not post. Match the revision printed on the PCB, read the original chip first, and confirm the file size equals the flash capacity.
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.
