Hi :) I'm having one last go to get my old giant Siemens DVB-C to work. It's one of these: http://www.vdr-wiki.de/wiki/index.php/Bild:Fujitsu-siemens_dvb-c.jpg PCI ID: 1131:7146 - the i2c dump of 0x50 is: 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: 00 00 11 0a 26 0f ff ff ff ff ff ff ff ff ff ff ..??&?.......... 10: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 20: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 40: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 60: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 70: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 80: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 90: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ a0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ b0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ c0: ff ff ff ff ff ff ff ff ff ff ff ff 96 e1 28 9a ............??(? d0: 5e 28 75 ec f2 93 63 35 9a a3 16 76 c9 77 64 bd ^(u???c5???v?wd? e0: 0a 0a 14 01 0d 0a 00 00 04 83 01 01 00 00 00 f0 ??????..????...? f0: 24 00 09 ff ff ff ff ff ff ff ff ff ff ff ff 50 $.?............P and this confuses me - I thought these old cards had 'Copyright Siemens' in 0x50, as per http://www.linuxtv.org/pipermail/linux-dvb/2005-August/004232.html (I also note all the other values at the end of the block are different) My last hope is that when 'playing' with the PWM, I accidentally did an 'i2cset' of a location other than 0xff and now the card won't lock at all. Is there another user who could post their EEPROM dump so I can compare it? Alternatively, am I likely to kill the card completely by changing the last 40-or so bytes to match those in Karl's post? Cheers, Gavin.
