BIOS firmware archive for the Acer Aspire 5742, built on the Compal PEW71 platform with motherboard LA-6582P. The LA-xxxxP numbering is Compal's, so the board itself comes from Compal rather than Acer. Extract the RAR and check that the image size matches the SPI flash chip on your board, because a wrong-size dump will not fit. Read and save the original chip contents with a programmer such as a CH341A before writing anything. It is typically used to recover a board that powers on with no display after a corrupted or failed BIOS update.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
