A 16.0 MB BIOS or firmware dump without a file extension, named 840 128 with a duplicate marker, which suggests a second copy of the same image. The name does not state the brand or the board number, and the meaning of 128 is not given. A 16 MB image corresponds to a 128 Mbit SPI flash chip, so check the chip marking before programming. Inspect the contents in a hex editor or a UEFI tool to confirm the platform, then back up the existing chip before flashing it with an external programmer.
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 @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
