BIOS firmware for the ASUS Transformer Book Flip TP550LD, provided as a 3.11 MB RAR archive. The name gives no board revision or version details, so the contents should be reviewed after extraction. Technicians write such an image to the SPI flash chip with a programmer when the convertible will not boot or has lost its firmware. Save a copy of the original chip first so unique data can be restored, verify the board markings on the PCB, and confirm that the image size fits the installed flash.
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.
