BIOS and EC firmware package for a board labelled IP3 AN12 MB V11, with a date code of 29 August 2019, supplied as a 3.97 MB RAR. The name gives no brand or model, so the target must be identified by matching this label on the PCB. Having both images lets a technician restore the system flash and the embedded controller, which matters for no power, battery or keyboard faults. Back up the existing chips first and confirm each image matches the capacity of the flash it goes to.
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.
