( the small metal component. use 0x00200000 for a 24.576 MHz crystal and 0x00187de7 for 32.11 MHz - for the TD1316 tuner, you will need the TDA9887_PRESENT flag. - you need an inputs entry for each input of the card. .vmux values are valid from 0 to 3, add 8 for s-video .amux can be LINE1, LINE2 or TV you can find the values by try and error. - add an entry in the saa7134_pci_tbl in saa7134-cards.c. You should insert it right before the entries for cards without eeprom. You need to enter the .subvendor and .subdevice entries that are reported by lspci for your card. You might need to add code in this file for remote control and initialization to analog mode. We don't know yet, but you might have a look at the SAA7134_BOARD_PHILIPS_EUROPA label in saa7134_board_init2(). You might need something similar. Now your card is autodetected and analog should work. Test! digital section: First get the documentation for the MT352. You will need it. The file you need to modify is saa7134-dvb.c and probably mt352.c. You can take the code for the Pinnacle 3001 as an example, but you will need to modify it. - first you need an entry in the dvb_init function and a data structure for the mt352_attach() function. - the code for the td1316 tuner is there. The IF frequency most probably is 36.167 MHz. - There must be something on your board that switches the AGC between analog and digital mode. This often is a 4052 analog multiplexer, controlled by some GPIO pin. I would guess it is one on the pins of the tda9886(7). From here on, you need to find things out yourself. Good luck Hartmut
