Raw BIOS dump for the Samsung R439 notebook, with an attached OKKK tag indicating a tested image. The file is 4 MB, which matches a 32 Mbit SPI flash chip. It is used to recover boards that do not start because of corrupted firmware, by writing the image with a programmer such as the CH341A. The name lists no board revision or BIOS version, so compare the board markings first, read and save the current chip contents, and verify after programming.
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.
