Hi

ftp://rah.star-gate.com/pub/bt848.tar.gz

With this release there is a better recognition mechanism for cards.

A new struct is introduced:
struct bt848_card_sig {
  int card;
  int tuner;
  u_char signature[Bt848_MAX_SIGN];
};

struct bt848_card_sig bt848_card_signature[1]= {
  /* IMS TURBO TV : card 5 */
    {  5,9, {00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 02, 00, 00, 00}}


};

bt848_card_sig.card holds a card number
bt848_card_sig.tuner holds a tuner number
bt848_card.signature holds the first 16 bytes of the signature probe test.

The program sign.c available from http://www.freebsd.org.~ahasty/Bt848.html
can be used to print the signature of your card or boot verbose.

If the recognition algorithm fails , you can still program the driver:
sysctl -w hw.bt848_card=<card-number>
sysctl -w hw.bt848_tuner=<tuner-number>
sysctl -w hw.bt848_reverse_mute=<0|1> 1 reverses the function of the tuner mute


I intent to check in the driver in about a week from now.


	Have Fun,
	Amancio
