BIOS for the Lenovo B460 laptop on board LA46 with discrete graphics, Wistron number 09911-1M, stored as a 1.80 MB rar. The DIS tag means a dedicated GPU version, which usually needs a different image than the integrated-graphics board. The 09911 style numbering is typical of Wistron-built Lenovo motherboards. Use an SPI programmer to write it when the system fails to start after a bad update, after reading and saving the original chip and checking that the board number and image size fit.
