BIOS firmware archive whose name carries BIC50E89382 and the part number PN08N1-0P53J00, with ND appended, in a 1.83 MB RAR. The name gives no clear brand or model, so identify the target board from these codes on the PCB or its label before use. Images like this are written to the SPI flash with an external programmer to restore a board with corrupted firmware. Read and save the original chip first, and confirm the image size matches the flash capacity.
