BIOS dump for a laptop mainboard numbered LA-C771P, a Compal board code, taken from or intended for a 25Q64FW SPI flash chip. The 8 MB raw image matches the 64 Mbit capacity of that chip, which is a 1.8 V part, so the programmer needs a suitable low-voltage adapter. Technicians write such a file with a CH341A or similar programmer when a board shows no POST or a corrupted firmware. Confirm the LA-C771P marking and revision on the PCB first, and always read and save the original chip contents before erasing it.
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 →
