28 How to add support for new cards
29 --------------------------------
30
31 The driver needs some config info for the TV c
32 cx88-cards.c. If the driver doesn't work well
33 entry for your card in that file. Check the k
34 to see whenever the driver knows your card or
35 like this one:
36
37 .. code-block:: none
38
39 cx8800[0]: subsystem: 0070:3400, board
40 34xxx models [card=1,autodetec
41
42 If your card is listed as "board: UNKNOWN/GENE
43 the driver. What to do then?
44
45 1) Try upgrading to the latest snapshot, maybe
46 meanwhile.
47 2) You can try to create a new entry yourself,
48 cx88-cards.c. If that worked, mail me your
49 diff ("diff -u").
50 3) Or you can mail me the config information.
51 following information to add the card:
52
53 - the PCI Subsystem ID ("0070:3400" from
54 "lspci -v" output is fine too).
55 - the tuner type used by the card. You c
56 trial-and-error using the tuner=<n> ins
57 know which one the card has you can als
58 list in CARDLIST.tuner
