25 | i2c communication for us, plus the common dvb-bt8xx device driver, | 28 | i2c communication for us, plus the common dvb-bt8xx device driver. |

27 | The frontends for Nebula DigiTV (nxt6000), Pinnacle PCTV Sat (cx24110), | 30 | TwinHan (dst) are loaded automatically by the dvb-bt8xx device driver. |
28 | TwinHan DST + clones (dst and dst-ca) are loaded automatically by the backend. | ||
29 | For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt. | ||
30 | 31 | ||
31 | 3a) The manual approach | 32 | 3a) Nebula / Pinnacle PCTV |
32 | ----------------------- | 33 | -------------------------- |
33 | 34 | ||
34 | Loading modules: | 35 | $ modprobe bttv (normally bttv is being loaded automatically by kmod) |
35 | modprobe bttv | 36 | $ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading) |
36 | modprobe dvb-bt8xx | ||
37 | 37 | ||
38 | Unloading modules: | ||
39 | modprobe -r dvb-bt8xx | ||
40 | modprobe -r bttv | ||
41 | 38 | ||
42 | 3b) The automatic approach | 39 | 3b) TwinHan and Clones |
43 | -------------------------- | 40 | -------------------------- |
44 | 41 | ||
45 | If not already done by installation, place a line either in | 42 | $ modprobe bttv i2c_hw=1 card=0x71 |
46 | /etc/modules.conf or in /etc/modprobe.conf containing this text: | 43 | $ modprobe dvb-bt8xx |
47 | alias char-major-81 bttv | 44 | $ modprobe dst |
45 | |||
46 | The value 0x71 will override the PCI type detection for dvb-bt8xx, | ||
47 | which is necessary for TwinHan cards. | ||
48 | |||
49 | If you're having an older card (blue color circuit) and card=0x71 locks | ||
50 | your machine, try using 0x68, too. If that does not work, ask on the | ||
51 | mailing list. | ||
52 | |||
53 | The DST module takes a couple of useful parameters. | ||
54 | |||
55 | verbose takes values 0 to 4. These values control the verbosity level, | ||
56 | and can be used to debug also. | ||
57 | |||
58 | verbose=0 means complete disabling of messages | ||
59 | 1 only error messages are displayed | ||
60 | 2 notifications are also displayed | ||
61 | 3 informational messages are also displayed | ||
62 | 4 debug setting | ||
63 | |||
64 | dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card. | ||
65 | 0x20 means it has a Conditional Access slot. | ||
66 | |||
67 | The autodected values are determined bythe cards 'response | ||
68 | string' which you can see in your logs e.g. | ||
48 | 69 | ||
49 | Then place a line in /etc/modules containing this text: | 70 | dst_get_device_id: Recognise [DSTMCI] |
50 | dvb-bt8xx | ||
51 | 71 | ||
52 | Reboot your system and have fun! | ||
