Raw 2.00 MB binary named only after a board position, U22, with no model, brand or version in the name. The designator suggests a dump read from the chip at location U22, and the size matches a 16 Mbit SPI flash. Without more context it should be treated as unidentified. Compare it against the board it came from, open it in a hex editor to look for vendor strings, and only write it to a matching 2 MB chip after saving a backup of the current contents.
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 @biosschematics. Enginerys does not host this file.
How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
