Small 1.00 MB .bin firmware image named simply 650, with no brand, board number or version in the name. A 1 MB size matches an 8 Mbit SPI flash, which on many laptops holds embedded controller or keyboard controller firmware, or BIOS on older platforms, so identify the target chip carefully. Search the file for text strings to confirm its purpose. Read and save the existing chip before writing, and never flash it to a chip of different capacity.
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 @biosfilebins. Enginerys does not host this file.
