ASUS firmware archive for the P2540FAC, revision R2.0, about 19.5 MB in RAR form. The name states only the model and revision, so the exact contents, such as a full BIOS dump or extra files, should be checked after extraction. A technician writes such an image to the SPI chip with a programmer to recover a board that does not boot. Verify the model and revision printed on the PCB, confirm the image size matches the flash capacity, and save the original chip contents before programming.
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.
