Firmware archive for the ASUS X542UA laptop, supplied as an 11.1 MB ZIP. The name gives no revision, version or ME state, so inspect the contents to tell whether it is a raw SPI dump or an official update capsule. Raw dumps can be written with a hardware programmer to recover a board that will not POST. Capsules are meant for EZ Flash instead. Check the motherboard revision on the PCB, back up the original chip and make sure the image size 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 @biosarchive. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
