A 3.86 MB RAR archive containing BIOS plus EC firmware for the ASUS VivoBook 15 X542BP, according to its name. The embedded controller code governs power sequencing, battery charging and keyboard functions, so restoring it together with the system BIOS can revive a dead or misbehaving board. Open the archive, identify which image belongs to which chip, and write each with an SPI programmer only after saving a backup of the original. Mismatched image and chip sizes indicate the wrong file.
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.
