Raw 8 MB BIOS binary for an Acer notebook on Compal board LA-D121P, as stated in the name. Compal uses the LA- prefix with a trailing P for its board numbers, so this is a Compal-built design sold under the Acer brand. An 8 MB image corresponds to a 64 Mbit SPI flash, which can be written directly with a programmer such as a CH341A. Confirm the LA number on the PCB, keep a backup of the existing chip contents, and check that the flash capacity matches before writing.
