MSI cx61- ms-16gb1 ver3.0 bios +EC

BIOS .zip 2.65 MB Shared

BIOS together with EC firmware for the MSI CX61 notebook on board MS-16GB1 version 3.0. MSI numbers its own boards in the MS-xxxxx format, and the version digit must agree with the marking on your PCB. The 2.65 MB ZIP covers both the system image and the embedded controller code, which manages power-on, charging and keyboard. Reflash with an SPI programmer after backing up the original chips, and verify each image size matches its target flash device before writing.
