# 4. Loading the Modules

This section is only for those whose modules don't load automatically and/or correctly. For a complete list of options by module, see Appendix A.

## 4.1. The Bttv Module

Once your card is installed, you can load the bttv module if your kernel hasn't already done it for you. Using the modprobe command as root, type

       # modprobe bttv

The modules `videodev` and `i2c` may be required prior to this if you are running a pre-2.4 series kernel. By default, the bttv will try to autodetect your card type; you can inspect /var/log/messages to see what it finds. If it doesn't autodetect properly, you can add the card=# option to the end of the previous command to force a your particular card type, a list of which are found in Appendix B or on your system in your kernel source Documentation if installed in the usual place (`/usr/src/linux`. If you get in trouble and need to remove the module, you can use rmmod:

       $ rmmod bttv

You can then reload the module with the appropriate options.

## 4.2. The Tuner Module

If necessary, load the tuner module, with

       # modprobe tuner

If the tuner is not correctly identified you may need to supply the magic number for tuner-type:

       # modprobe tuner type=#

You may need to dig into your case to see which tuner you have if you can't find the maker and model in the printed specifications that came with your hardware, or if this information is otherwise unavailable. It should be marked with the brand name and may support one or more of the three major broadcast standards in use in the world, whether NTSC, PAL or SECAM. In general, chipsets manufactured for the US market are NTSC; for Europe, PAL, and Asia PAL or SECAM. Some countries support more than one standard.

Once you have identified your tuner, select the value of n from the following list:

## 4.3. Other Modules

Don't forget to load any other modules you may need, including btaudio if you plan on recording or capturing audio to another application.

## 4.4. Automating the Module Loading Process

After you know which modules and options you need, you can automate the process by putting the information into `/etc/conf.modules` or `/etc/modules.conf`, depending on your distribution. Then, running an application which needs the driver will cause it to be loaded automatically with the appropriate options. The following is an example entry:

     # TV
     alias	char-major-81    bttv
     pre-install bttv        modprobe -k tuner; modprobe -k msp3400
     options                 bttv               radio=1  card=3
     options tuner           type=2
