The Device Driver Utility runs automatically when you boot an installed system. You can also manually start the Device Driver Utility after you have installed the Oracle Solaris OS.
To start the Device Driver Utility from the text installer, choose Install Additional Drivers from the initial menu.
To start the Device Driver Utility from the desktop of an installed system, choose Applications → System Tools → Device Driver Utility from the main menu.
The Device Driver Utility scans your system and then displays a list of the devices that are detected. For each device that is detected, the list displays information such as the manufacturer, the model, and the name of the driver that is currently managing the device.
If the utility detects a device that does not have a driver attached, that device is selected on the device list. You can display more information about the device and install the missing driver. See How to Install Missing Drivers.
