With controller firmware 7.86.32.00 and later, the DSM is supported on Windows 64bit ONLY. Please do not upgrade any storage subsystem to controller firmware to 7.86.32.00 or later if that storage subsystem has 32bit Windows hosts attached. The 7.8x.xx.xx release contains significant new function in addition to firmware fixes. It will also change the look and feel of the Storage Manager GUI being used to manage the subsystems running 7.8x.xx.xx controller firmware. Please review the Readme and product documentation before installing this firmware since once it is installed it will not be possible to return to a prior firmware level (7.7x or earlier).
