BIOS image for an H61H2-A2 Deluxe motherboard, version 2, intended for a 4 MB flash chip as the name states, delivered in a 2.37 MB ZIP archive. The H61 chipset designation indicates an Intel desktop platform for Sandy Bridge and Ivy Bridge processors. Such dumps are written to the SPI chip with an external programmer when the board no longer starts after a failed update. Read and keep the original contents first, check that the chip really is 32 Mbit, and make sure the board marking matches the file.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
