Embedded controller firmware packed as a 58.3 KB zip, judging by the EC.bin name. No brand, model or board number is given, which makes the file risky to use without other identification. EC firmware handles power sequencing, charging, keyboard and fan control, and a wrong image can leave a board dead or unable to charge. Confirm the matching board and EC chip from the folder it came with, compare the size against the EC flash, and dump the existing EC contents before programming anything.
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.
