Hi :)

I'm having one last go to get my old giant Siemens DVB-C to work. It's one of 
these:

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

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.
