BIOS firmware for the Dell Precision T5500 workstation, packed in a RAR archive of about 888 KB. The name gives no BIOS version, flash chip type or board revision, so check the unpacked image size against the capacity of the SPI chip on your board before programming. Technicians use such dumps to recover a board with corrupted firmware by writing the chip with an external programmer like a CH341A. Read and save the original contents first, because service tag and system data stored there may be lost when overwritten.
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.
