Hauppauge WinTV-HVR-4000 / Nova-HD-S2

Whats the command to extract the firmware from the new driver release at
http://www.wintvcd.co.uk/drivers/88x_2_123_27056_WHQL.zip

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.
