Firmware archive for the ASUS ZenBook UX330UA and UX330UAK, 5.46 MB in RAR format; the name gives no version or EC details, so open it to see which images are inside. It is intended for reprogramming the BIOS chip with an external programmer when the ultrabook will not boot. Back up the original SPI contents first because they hold the unique serial data, confirm the image size matches the chip, and check the board revision on the PCB matches your unit.
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.
