BIOS archive for the Lenovo ThinkPad T430, here labelled IBM, with board code NZM4H-7 in the name and a DIS tag meaning the discrete graphics version. The RAR is 4.84 MB. A technician uses the dump to recover a board that will not start or to rewrite a corrupted SPI chip with a programmer and clip. The T430 splits firmware across two flash chips, so confirm which chip this image belongs to by its size. Always save your own reads first, as they hold the serial and system data.
