Zipped BIOS image labelled L430 LCD-1 MB 11248-4, about 3.21 MB compressed. L430 probably means the Lenovo ThinkPad L430, and 11248-4 looks like a board number, though the name confirms neither. The LCD-1 MB part is unclear and may describe a display variant or the chip the dump came from. Unpack it and check the image size against the flash chip before writing. Confirm the board marking and back up the original, because ThinkPad firmware stores machine-specific data.
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 @BiosSupport2006. Enginerys does not host this file.
