But I can tell you how to work it out. The problem is how to determine the offset to use. Look at this hex dump from the start of each firmware file: dvb-fe-cx24116-1.20.79.0.fw: 00000000 02 11 f9 ec 33 50 03 12 dvb-fe-cx24116-1.22.82.0.fw: 00000000 02 11 fb ec 33 50 03 12 dvb-fe-cx24116-1.23.86.1.fw: 00000000 02 12 02 ec 33 50 03 12 Note the magic `33 50 03 12` bytes that appear at offset 4 in each firmware file. You can use that to determine the offset of the firmware in the `hcw88bda.sys` file (at least for the existing firmware files). I used `hd hcw88bda.sys | more` and typed `/33 50 03 12` in `more` to find the offset. Make sure to subtract 4 from the offset of the `33 50 03 12` bytes. Convert the offset from hex to decimal and use that as the `skip` amount for the `dd` command. Verify the extracted firmware using `md5sum`. Perhaps when you get it to work you could update the wiki page you mentioned.
