Recently purchased 2x 256GB Samsung 830 Series SSDs (MZ-7PC256N/AM) for installation on a dual LGA2011 socket based Asus Z9PE-D8 WS workstation motherboard which uses the Intel C602 Chipset.
Both Samsung 830 SSDs had older CXM01B1Q firmware on them. So tried using Samsung Magician software in Windows 7 Ultimate to update to CXM03B1Q firmware but the firmware update kept failing. So ended up having to use the included Firmware Update Tool ISO CD image (FW_Update_Tool_CXM03B1Q.iso) to update the firmware.
Below is screenshot guide to updating Samsung 830 Series SSD using included ISO CD image.
