Raw BIOS dump labelled P8H61-M LX3, which corresponds to the ASUS P8H61-M LX3 desktop motherboard, though no brand is stated. The 4.00 MB .bin file matches a 32 Mbit SPI flash chip and can be written directly with a programmer such as a CH341A. Typical use is reviving a board that powers on with no post after a bad update. Make sure the model printed on the PCB is the LX3 variant and not a similar LX board, and back up the original chip before flashing.
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 .bin 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 →
