BIOS archive for the LG 15U34 and 15U340 notebooks, a 5.33 MB ZIP that names no board number, version or revision. Open it to see whether it holds a single SPI image or several files, then check each size against the flash chip capacity. Technicians write such images with a hardware programmer to bring back a machine that will not boot. Always dump and keep the original firmware before writing, so the change can be undone.
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.
How to open a .zip file
