BIOS image for a G405, the AMD-based version, 4.00 MB in raw binary form; no brand or board number appears in the name. The file size matches a 32 Mbit SPI flash chip. Since models of this kind may ship with Intel and AMD boards, the AMD tag matters when choosing firmware. Flash it with a hardware programmer only after checking the board number on the PCB, confirming the chip size, and saving a backup read of the original chip.
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 @bios_laptop. Enginerys does not host this file.
