Firmware dump for the Acer Aspire 5552 on the PEW76 platform, marked for the AMD Athlon II processor build. The name gives no full board number, so confirm the motherboard code on the PCB before use. At 999 KB, the RAR likely holds an image for a 1 MB class SPI chip. Technicians flash it externally to recover a board with no POST after BIOS corruption. Read and save the original chip contents first, and check that the extracted file exactly equals the capacity of the installed flash memory.
