Compressed BIOS package for ASUS laptops of the X552E and X550EP series, two closely related models sharing a firmware base according to the name. No board revision or version number is given, so confirm compatibility against the mainboard label before use. The archive is meant for restoring a corrupted SPI flash with an external programmer such as a CH341A. Read and keep the original chip contents first, and check that the image size matches the capacity of the flash chip fitted on the board.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
