Raw 4.00 MB BIOS binary for the Lenovo G505 AMD version, with no board number or revision in the name. The size matches a 32 Mbit SPI flash chip, the type used to store firmware on these boards. A dump like this is written with an external programmer to revive a board with corrupted firmware. Because the exact board is not stated, identify the number printed on your PCB first, check whether it has discrete or integrated graphics, and read and save the original chip contents before writing.
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.
