BIOS binary for the Lenovo IdeaCentre 310S-08IAP desktop, with O2XKT30A in the file name, likely the firmware version code. Packed as a 5.37 MB ZIP containing a .bin image. It is intended for reprogramming the SPI flash with an external programmer when the system is dead after a failed update. Read and save the original chip first, since it holds the serial and system identifiers, and confirm that the image size matches the flash chip capacity.
