I had to override the tuner detection and I'm not > sure how to decide, if it's a Temic or Phillips PAL tuner. Both have > their read/write address at 0xc2/0xc3. 2 programs are available that would be useful for a better board detection scheme: With eeprom.c you can record the contents of the on-board EEProm. Invoke as "eeprom 0 256" (Wincast/TV) or "eeprom 0 128" (STB TV/PCI). eeprom contents vary from 1 board to the next within thew same model, among other things will often be a serial #. there is no documentation available on the contents, so reverse engineering is in order... With sign.c you can record the "signature" of your card. This is the location of all i2c parts on the card. Although 2 different tuners might use the same address for 1 part, the overall combination of parts might be different enough to make a decision... between the 2 hopefully a method of detecting all tuners/boards could be devised. source for both programs is on the bt848 page. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
