BIOS dump packed in a ZIP of about 5.52 MB for a laptop motherboard DAX61CMB6D0, revision D according to the name. The DA-prefixed numbering with an MB segment is the scheme used by Quanta, an ODM building notebooks for many brands, so the laptop brand is not stated here. The file is meant for reflashing the SPI BIOS chip with a hardware programmer when the firmware is corrupted. Read and save the original chip contents first, and verify the board revision and chip capacity match the image.
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 @nityatechnology2020. Enginerys does not host this file.
