BIOS dump labelled fully working for Compal board LA-E551P, project CIZY3, revision 2.0, with a date of 2017-01-12 in the name. Packed as RAR, it needs extracting before writing to the SPI flash with a hardware programmer to revive a board with corrupted firmware. LA-xxxxP is Compal's ODM numbering, and such boards ship under various laptop brands. Save a copy of the original chip contents first and check the image size against the flash chip. Match board number and revision before flashing.
