Most eeproms also tell us the 550 * tuner type and other features of the the cards. 551 * 552 * The current probe code works as follows 553 * A) If the card uses a Bt878/879: 554 * 1) Read the sub-system vendor id from the configuration EEPROM. 555 * Select the required tuner, audio mux arrangement and any other 556 * onboard features. If this fails, move to step B. 557 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879: 558 * 1) Look for I2C devices. If there are none fitted, it is an Intel or 559 * VideoLogic cards. 560 * 2) Look for a configuration EEPROM. 561 * 2a) If there is one at I2C address 0xa0 it may be 562 * a Hauppauge or an Osprey. Check the EEPROM contents to determine which 563 * one it is. For Hauppauge, select the tuner type and audio hardware. 564 * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card. 565 * We still have to guess on the tuner type. 566 * 567 * C) If we do not know the card type from (A) or (B), guess at the tuner 568 * type based on the I2C address of the tuner. 569 * 570 * D) After determining the Tuner Type, we probe the i2c bus for other 571 * devices at known locations, eg IR-Remote Control, MSP34xx and TDA 572 * stereo chips. 573 */ 574 575 576 /* 577 * These are the sub-system vendor ID codes stored in the 578 * configuration EEPROM used on Bt878/879 cards.
