Installation
An installable
driver can carry out driver-specific installation tasks when processing the DRV_INSTALL and DRV_REMOVE messages. An installation
application, such as a Control Panel application, sends the messages to the
driver when installing or removing the driver, respectively.
When
processing the DRV_INSTALL message, the driver typically verifies that the
required hardware is present and then displays the configuration dialog box to
let the user choose the initial configuration settings for the driver and
associated hardware. The message includes the address of a DRVCONFIGINFO structure that contains
the names of the registry key and value associated with the driver; the driver
checks the registry value for default configuration information. Finally, the
driver also creates any additional registry keys and values needed for
successful operation.
When
processing the DRV_REMOVE message, the driver removes any registry keys and
values it may have created.
