BIOS package in a 14.7 MB RAR for a board labelled NB6200 MB DIS V7, where DIS indicates the discrete graphics variant and V7 the board version. The name also carries a firmware build string, WinJ4CN39WW, which looks like a Lenovo-style BIOS version code. Use the image to rewrite a corrupted SPI flash chip with a programmer such as a CH341A. Read and save the original chip contents first, and make sure the image size matches the chip capacity, otherwise it will not fit.
