Working BIOS dump for a Lenovo ThinkPad T430s, LSN-4 motherboard 11263-1, UMA integrated graphics version, in a 5.07 MB ZIP. The five-digit number with a dash suffix is a Wistron board code. Write the image to the SPI flash with a hardware programmer to recover a board with damaged firmware. Read the original chip first, since it carries serial and system data, and check the PCB for 11263-1 and integrated-only graphics, because discrete GPU boards use different firmware.
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.
