Firmware package for the ASUS X556UQK with motherboard revision 3.1. The 5.31 MB archive is larger than a single compressed image usually is, so it may contain several files or variants; review them before choosing one to flash. ASUS prints its board model and revision on the PCB, and both should match here. Technicians write such dumps with an SPI programmer to recover dead or boot-looping boards; always keep the original chip read and verify the image matches the flash capacity.
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 @biosfiles. Enginerys does not host this file.
