BIOS archive for the HP EliteBook 810 G2 on motherboard 13246-1; the BIOS2 suffix suggests a second dump, though the name does not explain it. The five-digit and dash pattern is the numbering used by Wistron, the board maker for this model. The 6.27 MB RAR needs to be unpacked and its contents matched to the flash chip before writing with a programmer. Save the original image first, since HP boards hold serial and other system data, and confirm the board number on the PCB.
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.
