BIOS and EC firmware set for an Acer Aspire A515 laptop built on Compal board LA-G521P, archived as an 11.3 MB rar. Compal's LA-xxxxP numbering marks it as the ODM, and the embedded controller firmware matters as much as the BIOS on these boards for power-on, charging and keyboard functions. Write the files with an SPI programmer such as a CH341A. Dump and keep the existing chip contents first, and check that each image size equals the capacity of its target flash chip.

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 →
