BIOS package for the ASUS ZenBook UX325EA, with the name citing the NB2555 PCB mainboard at version 4, tested by FST FIX. The 7.06 MB RAR archive is used to restore the SPI flash with an external programmer on thin laptops that do not post or lost their firmware. Confirm the NB2555 marking and V4 revision on your board before writing. Read and keep a copy of the original contents, which may hold serial and identity data, and make sure the extracted image size matches the installed chip.
