BIOS for the ASUS PRO552L, a business model that uses the P552LA and P552LJ mainboard at revision 2.0, supplied as a 3.67 MB ZIP. The LA and LJ suffixes mark two configurations of the same board, which the name says this image covers. Technicians reflash the SPI chip with a programmer to fix no-boot faults or failed updates. Check the revision on the PCB, read and keep the original chip contents, which hold the serial and system data, and confirm the image size fits the flash chip.
