Raw BIOS dump for the Quanta mainboard DAX1BDMB6F0, stored without a file extension, 8.00 MB in size, which matches a 64 Mbit SPI flash. Quanta board numbers start with DA, followed by the project code, MB for mainboard and a revision letter, here F, all printed on the PCB. The name gives no laptop model, so confirm the board marking directly. Rename to .bin if your programmer needs it, back up the original chip, then write and verify 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 @biosarchive. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
