The driver at http://www.wintvcd.co.uk/drivers/88x_2_122_26109_WHQL.zip
is no longer available, so the link on

Hi Jonas,
I can't remember the exact command off the top of my head. 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.
