Dell BIOS archive for the Cedar AMD platform on Wistron board 13283-1, marked OK by the uploader, meaning it reportedly booted after flashing. The RAR weighs 4.20 MB, so extract it and confirm that the image size fits the SPI chip on your board. Wistron uses this five-digit code with a dash revision on many Dell Inspiron boards, so check the PCB label before use. Read and archive the original chip with a programmer first, since it stores the service tag and other unit-specific data.
