- This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge or Technotrend
- windows driver saved as '/usr/lib/hotplug/firmware/tda1004x.bin'.
- You can also pass the complete file name with the module parameter 'tda1004x_firmware'.
-
- Currently the DLL from v2.15a of the technotrend driver is supported. Other versions can
- be added reasonably painlessly.

- Windows driver URL: http://www.technotrend.de/
+ * This driver needs external firmware. Please use the commands
+ * "<kerneldir>/Documentation/dvb/get_dvb_firmware tda10045",
+ * "<kerneldir>/Documentation/dvb/get_dvb_firmware tda10046" to
+ * download/extract them, and then copy them to /usr/lib/hotplug/firmware
+ * or /lib/firmware (depending on configuration of firmware hotplug).
