ASUS X550CL firmware package for mainboard revision 2.0, supplied as a 3.65 MB zip archive. The name states only the model and board revision, so there is no mention of ME cleaning, EC code or the flash chip used. A dump like this is typically written directly to the motherboard SPI BIOS chip with an external programmer when the laptop powers on but shows no image or loops on startup. Make sure the revision silkscreened on the PCB really reads 2.0, keep a backup read of the existing chip, and verify the file size matches the chip capacity before writing.
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 →
