Firmware dump for the Acer Aspire 6920 series, labelled as the Intel Core 2 Duo model with the code LF1. The 552 KB RAR is intended for reprogramming the BIOS chip with an external SPI programmer to bring back a laptop that shows no display or cycles power after a failed update. Since the name lists no full board number, check the PCB markings carefully. Read and save the existing chip contents and compare image size with flash capacity before writing.
