26which is called the backend. 29The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110) and
27The frontends for Nebula DigiTV (nxt6000), Pinnacle PCTV Sat (cx24110), 30TwinHan (dst) are loaded automatically by the dvb-bt8xx device driver.
28TwinHan DST + clones (dst and dst-ca) are loaded automatically by the backend.
29For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt.

313a) The manual approach 323a) Nebula / Pinnacle PCTV
32----------------------- 33--------------------------
33 34
34Loading modules: 35 $ modprobe bttv (normally bttv is being loaded automatically by kmod)
35modprobe bttv 36 $ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading)
36modprobe dvb-bt8xx
37 37
38Unloading modules:
39modprobe -r dvb-bt8xx
40modprobe -r bttv
41 38
423b) The automatic approach 393b) TwinHan and Clones
43-------------------------- 40--------------------------
44 41
45If 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
47alias char-major-81 bttv 44 $ modprobe dst
45
46The value 0x71 will override the PCI type detection for dvb-bt8xx,
47which is necessary for TwinHan cards.
48
49If you're having an older card (blue color circuit) and card=0x71 locks
50your machine, try using 0x68, too. If that does not work, ask on the
51mailing list.
52
53The DST module takes a couple of useful parameters.
54
55verbose takes values 0 to 4. These values control the verbosity level,
56and can be used to debug also.
57
58verbose=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
64dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
650x20 means it has a Conditional Access slot.
66
67The autodected values are determined bythe cards 'response
68string' which you can see in your logs e.g.
48 69
49Then place a line in /etc/modules containing this text: 70dst_get_device_id: Recognise [DSTMCI]
50dvb-bt8xx

52Reboot your system and have fun!
