BIOS dump for the Acer Aspire 5542, board JV50-TR, read from the chip at position U9 according to the name. The raw 2 MB BIN matches a 16 Mbit SPI flash and is intended for programming with an external programmer when the laptop shows no display or is stuck after a failed update. Confirm the JV50-TR marking on the PCB, read the existing chip first and save it, and make sure the target flash has the same 2 MB capacity before writing the image.
