1.4       hunold      1: How to get the Nebula, PCTV and Twinhan DST cards working
                      2: =========================================================
1.1       holger      3: 
1.6       hunold      4: This class of cards has a bt878a as the PCI interface, and require the
                      5: bttv driver.
1.2       honan       6: 
1.6       hunold      7: Please pay close attention to the warning about the bttv module options
                      8: below for the DST card.
1.2       honan       9: 
1.8     ! hunold     10: 1) Loading Modules
1.4       hunold     11: ==================
1.1       holger     12: 
1.6       hunold     13: In general you need to load the bttv driver, which will handle the gpio
                     14: and i2c communication for us. Next you need the common dvb-bt8xx device
                     15: driver and one frontend driver.
                     16: 
                     17: The bttv driver will HANG YOUR SYSTEM IF YOU DO NOT SPECIFY THE
                     18: COORECT  CARD ID! A list of possible card ids can be found inside
1.7       hunold     19: "bttv-cards.c" inside the bttv driver package.
1.1       holger     20: 
1.2       honan      21: Pay attention to failures to load these frontends. 
                     22: (E.g. dmesg, /var/log/messages).

1.8     ! hunold     24: 2a) Nebula / Pinnacle PCTV
1.4       hunold     25: --------------------------
                     26: 
                     27:    $ modprobe bttv i2c_hw=1 card=0x68
                     28:    $ modprobe dvb-bt8xx
                     29:    
                     30: For Nebula cards use the "nxt6000" frontend driver:
                     31:    $ modprobe nxt6000
                     32: 
                     33: For Pinnacle PCTV cards use the "cx24110" frontend driver:
                     34:    $ modprobe cx24110
                     35:

1.4       hunold     37: -----------
                     38: 
                     39:    $ modprobe bttv i2c_hw=1 card=0x71
                     40:    $ modprobe dvb-bt8xx
                     41:    $ modprobe dst
1.3       honan      42: 
1.6       hunold     43: The value 0x71 will override the PCI type detection for dvb-bt8xx,
1.7       hunold     44: which  is necessary for TwinHan cards.
1.6       hunold     45: 
                     46: If you're having an older card (blue color circuit) and card=0x71 locks
                     47: your machine, try using 0x68, too. If that does not work, ask on the
                     48: mailing list.
1.3       honan      49: 
1.6       hunold     50: The DST module takes a couple of useful parameters, in case the dst
                     51: drivers fails to detect your type of card correctly.
1.3       honan      52: 
                     53: dst_type takes values 0 (satellite), 1 (terrestial TV), 2 (cable).
                     54: 
                     55: dst_type_flags takes bit combined values:
                     56: 1 = new tuner type packets. You can use this if your card is detected
                     57:     and you have debug and you continually see the tuner packets not
                     58:     working (make sure not a basic problem like dish alignment etc.)
                     59: 
                     60: 2 = TS 204. If your card tunes OK, but the picture is terrible, seemingly
                     61:     breaking up in one half continually, and crc fails a lot, then
                     62:     this is worth a try (or trying to turn off)
                     63: 
                     64: 4 = has symdiv. Some cards, mostly without new tuner packets, require
                     65:     a symbol division algorithm. Doesn't apply to terrestial TV.
                     66: 
                     67: You can also specify a value to have the autodetected values turned off
                     68: (e.g. 0). The autodected values are determined bythe cards 'response
                     69: string' which you can see in your logs e.g.
                     70: 
                     71: dst_check_ci: recognize DST-MOT
                     72: 
                     73: or 
                     74: 
                     75: dst_check_ci: unable to recognize DSTXCI or STXCI
