BIOS ROM for the MSI GP70 2QE gaming notebook, version string E175AIMS.10H, which marks an AMI BIOS for board MS-175A. The I545 in the name probably refers to a model configuration, which the name does not explain. Delivered as a .rom inside a ZIP of about 2.37 MB, so it may be a BIOS region rather than a full chip dump. Check that it matches your SPI chip size and layout before writing with a programmer. Back up the original contents so the ME and serial data are not lost.
