Firmware package for the Lenovo B320i all-in-one, with the identifier 6150A0003605 given in the file name, likely a board or part code. The 2.20 MB zip holds the BIOS image to restore a corrupted flash chip on that system. Typical use is to desolder or clip onto the SPI chip, read and save the existing data, then write this image with a programmer. Before flashing, compare the code printed on your board with the one in the name and make sure the image size fits the flash chip.
