Firmware archive of 763 KB in RAR form, named L-A780 with revision 1.0. The name does not identify the brand, chip or version, so the exact board must be confirmed from the PCB before use. Such a dump is intended for restoring the BIOS chip of a board whose firmware is corrupted, typically with an external SPI programmer and clip. Open the archive, compare the image size with the installed flash chip, check that the board revision is 1.0, and read the original contents to a backup before writing.
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 @afsbiosfree. Enginerys does not host this file.
