BIOS image for the MSI CX640DX laptop, built by Pegatron on the A17HC board, with the additional code 0138075 included in the name. The 1.98 MB RAR serves to reprogram the SPI flash when the notebook does not start or shows a blank screen after a bad update. Pegatron was the ODM behind this MSI design, so match the A17HC marking on the PCB before using the file. Read and save the original chip contents first, and check that the dump size equals the flash chip capacity.
