System BIOS image for the Acer Aspire E1-531 on the Compal LA-7912P mainboard, a raw 4.00 MB binary suited to a 32 Mbit SPI flash chip. Compal prints LA-xxxxP board codes on its PCBs, and this board also served the E1-571 and Gateway models. A matching EC file exists separately, since the embedded controller uses its own firmware. Check the board label and chip capacity, read and keep the original contents, then program the dump with an external programmer such as a CH341A.
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.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
