BIOS image for a Medion S2218 monitor or device, with the inner file named EF20RAX.BIN inside a 1.21 MB ZIP. The name gives no board revision or chip details, so check the contents and identify the flash chip on the board before use. Such a dump is written with an SPI or EEPROM programmer to recover a unit stuck at boot or showing faults after a failed update. Back up the current chip contents, and make sure the file size equals the capacity of the installed chip.
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.
