Firmware archive identified only by the board code IP3_IN16_MB with version V30 and the date 20201105A; no brand or laptop model appears in the name. The same code appears on another listing for a Toshiba dynabook machine, but this copy does not confirm it. Inspect the archive before use and match the board code silk-screened on the PCB. Read and keep the original flash contents with a programmer, and check that the image size equals the SPI chip capacity before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
