BIOS image for an H61H2 motherboard at revision A1.0, packed as a ZIP, with the name stating a 4 MB flash chip. H61 refers to Intel's H61 desktop chipset. Technicians write images like this with an SPI programmer to fix boards stuck on no POST after a failed update. Make sure the extracted file is exactly 4 MB to match the chip, and confirm the revision printed on the PCB. Save a dump of the original chip before erasing, since the onboard LAN MAC address may be stored in 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.
