BIOS for what is likely an ASUS X55A-series board, given the X55AF prefix, with firmware version 417 and board revision 2.1 stated, labelled as working. No brand is confirmed in the name, and the archive is a 3.42 MB RAR. Make sure the model and revision on the PCB match before trusting the image. ASUS files of this type may need the capsule header removed before being written directly to SPI flash. Read and back up the original chip with a programmer, then check the size matches the flash capacity.
