> If the **preload** field in the configuration file is set to **0** (DEVICE\_PRELOAD\_ENABLE), the driver is loaded by default during the system boot process. If **preload** is set to **1** (DEVICE\_PRELOAD\_ENABLE\_STEP2), the driver is loaded after a quick start is complete if the system supports quick start. If the system does not support quick start, the value **1** has the same meaning as DEVICE\_PRELOAD\_ENABLE. If **preload** is set to **2** (DEVICE\_PRELOAD\_DISABLE), the driver is dynamically loaded instead of being loaded during the system boot process. When a user-mode process requests the driver service (for details, see [Driver Message Mechanism Management](driver-hdf-message-managements.md)), the HDF attempts to dynamically load the driver if the driver service does not exist.

> In the configuration file, the **priority** field \(the value is an integer ranging from 0 to 200\) indicates the priority of the host and driver. For drivers in different hosts, a smaller host priority value indicates a higher driver loading priority; for drivers in the same host, a smaller driver priority value indicates a higher driver loading priority.
