BIOS dump for the LG 15U340 laptop, a 3.06 MB RAR archive whose name also carries the number 13894, possibly a version or build identifier. No board number or revision is given, so compare the image size with the SPI flash chip on the board before writing. Use an external programmer to restore corrupted firmware. Save the original chip contents first, since they may hold serial and configuration data unique to that machine.
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.
