The Firmware Upgrade Utility main screen appears. The devices capable
of being upgraded are listed in the Device List panel:
4. Click Next to perform the upgrade.
If you enabled Check Firmware Version , the utility compares the device's
firmware level with that of the upgrade files. If it finds that the device's
version is higher than the upgrade version, it brings up a dialog box
informing you of the situation and gives you the option to continue or cancel.
If you didn't enable Check Firmware Version , the utility installs the
upgrade files without checking whether they are a higher level, or not.
As the upgrade proceeds, status messages appear in the Status Messages
panel, and the progress toward completion is shown on the Progress bar.
