BIOS for the ASUS Z450LA laptop, board revision 2.0, stored in a 10.1 MB rar archive. A dump like this restores corrupted or bricked firmware when written directly to the SPI flash with a CH341A or similar programmer, via clip or with the chip removed. ASUS images may include board-specific data, so read and keep the original chip before writing. Confirm the board revision printed on the PCB matches 2.0 and that the image size equals the capacity of the fitted flash chip.
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.
