| 7 | Please pay close attention to the warning about the bttv module | 7 | This class of cards has a bt878a chip as the PCI interface. |
| 8 | options below for the DST card. | 8 | The different card drivers require the bttv driver to provide the means |
| 9 | to access the i2c bus and the gpio pins of the bt8xx chipset. | ||

| 24 | 2) Loading Modules | 21 | 3) Loading Modules, described by two approaches |
| 25 | ================== | 22 | =============================================== |
| 26 | 23 | ||
| 27 | In general you need to load the bttv driver, which will handle the gpio and | 24 | In general you need to load the bttv driver, which will handle the gpio and |
| 28 | i2c communication for us, plus the common dvb-bt8xx device driver. | 25 | i2c communication for us, plus the common dvb-bt8xx device driver, |
| 29 | The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110) and | 26 | which is called the backend. |
| 30 | TwinHan (dst) are loaded automatically by the dvb-bt8xx device driver. | 27 | The frontends for Nebula DigiTV (nxt6000), Pinnacle PCTV Sat (cx24110), |
| 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. | ||
| 31 | 30 | ||
| 32 | 3a) Nebula / Pinnacle PCTV | 31 | 3a) The manual approach |
| 33 | -------------------------- | 32 | ----------------------- |
| 34 | 33 | ||
| 35 | $ modprobe bttv (normally bttv is being loaded automatically by kmod) | 34 | Loading modules: |
| 36 | $ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading) | 35 | modprobe bttv |
| 36 | modprobe dvb-bt8xx | ||
| 37 | 37 | ||
| 38 | Unloading modules: | ||
| 39 | modprobe -r dvb-bt8xx | ||
| 40 | modprobe -r bttv | ||
| 38 | 41 | ||
| 39 | 3b) TwinHan and Clones | 42 | 3b) The automatic approach |
| 40 | -------------------------- | 43 | -------------------------- |
| 41 | 44 | ||
| 42 | $ modprobe bttv i2c_hw=1 card=0x71 | 45 | If not already done by installation, place a line either in |
| 43 | $ modprobe dvb-bt8xx | 46 | /etc/modules.conf or in /etc/modprobe.conf containing this text: |
| 44 | $ modprobe dst | 47 | alias char-major-81 bttv |
| 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 | 48 | ||
| 55 | a. verbose takes values 0 to 5. These values control the verbosity level. | 49 | Then place a line in /etc/modules containing this text: |
| 56 | b. debug takes values 0 and 1. You can either disable or enable debugging. | 50 | dvb-bt8xx |
| 57 | c. dst_addons takes values 0 and 0x20: | ||
| 58 | - A value of 0 means it is a FTA card. | ||
| 59 | - A value of 0x20 means it has a Conditional Access slot. | ||
| 60 | 51 | ||
| 61 | The autodetected values are determined by the "response string" | 52 | Reboot your system and have fun! |
| 62 | of the card, which you can see in your logs: | ||
| 63 | e.g.: dst_get_device_id: Recognize [DSTMCI] | ||
