You can verify several parameters of the device driver software.

To verify that the ipr device driver for the controller is installed, type modinfo ipr | grep version.
Data is displayed in this form:
```
version:        2.6.0
srcversion:     D720FC6935DA2B2638B177A
```
To verify the ipr device driver version, type # modinfo -F version ipr.
You will see data in this form:
```
2.6.0
```
To verify that the iprconfig utility is installed, type iprconfig –version.
Output from this command will indicate if the utility is installed, and if so, version information will be displayed.
