Firmware archive for the ASUS X550CL laptop, board revision 2.1, packed as a 3.62 MB RAR. The name does not say whether it holds a full SPI dump, an EC image or an update file, so extract it and check the file sizes against the flash chip installed on the board. ASUS X550 boards are commonly revived by reprogramming the BIOS chip with a programmer. Match revision 2.1 printed on the motherboard, read and save the original chip, and verify the written data afterward.
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.
