Keyboard controller firmware dump, the name indicating a KBC original read, provided as a 256 KB binary. No model or board number is given, so this file is hard to use without knowing its source. KBC or EC firmware governs power-up, charging, fans and keyboard handling, and a corrupt image often leaves a board dead. Write it only to the matching controller or flash chip with a suitable programmer, after confirming the board and saving its current contents.
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 @bios_laptop. Enginerys does not host this file.
