7z archive containing BIOS for the Lenovo B50-80 laptop on the Compal LA-B091P mainboard, revision 2.0, with E1ZIWB2302 also in the name, likely a source or version tag. The 3.24 MB compressed size suggests a full SPI image, possibly with notes. LA-xxxxP is Compal's board numbering. Extract, compare the image size with the flash chip on the board, and save the original read before writing with an external programmer to recover a unit with no display or a corrupted firmware region.
