|
||||
General information
|
||||
-------------------
|
||||
|
||||
This class of cards has a bt878a as the PCI interface, and require the bttv driver
|
||||
for accessing the i2c bus and the gpio pins of the bt8xx chipset.
|
||||
Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
|
||||
|
||||
Compiling kernel please enable:
|
||||
a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Enable Video for Linux API 1 (DEPRECATED)"
|
||||
b.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Video Capture Adapters" => "BT848 Video For Linux"
|
||||
c.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
|
||||
|
||||
Please use the following options with care as deselection of drivers which are in fact necessary
|
||||
may result in DVB devices that cannot be tuned due to lack of driver support:
|
||||
You can save RAM by deselecting every frontend module that your DVB card does not need.

Then please select your card-specific frontend module.

Loading Modules

Probing the cards with broken PCI subsystem ID

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are some TwinHan cards that the EEPROM has become corrupted for some

reason. The cards do not have correct PCI subsystem ID. But we can force

probing the cards with broken PCI subsystem ID
