Hi,

We (including me) have no indication if Renesas bothered or not. Maybe
they tried but could not convince a third party. I don't know.

Sure thing!

Opera firmware
==============

Author: Marco Gittler <g.marco@freenet.de>

To extract the firmware for the Opera DVB-S1 USB-Box
you need to copy the files:

2830SCap2.sys
2830SLoad2.sys

from the windriver disk into this directory.

Then run:

.. code-block:: none

	scripts/get_dvb_firmware opera1

and after that you have 2 files:

dvb-usb-opera-01.fw
dvb-usb-opera1-fpga-01.fw

in here.

Copy them into /lib/firmware/ .

After that the driver can load the firmware
(if you have enabled firmware loading
in kernel config and have hotplug running).

=== snap

And this is probably not the only driver where you need to get firmware
out of a Windows driver (media drivers and webcam drivers are good
candidates). And the redistribution of such drivers is likely to be
limited as well.

Happy hacking,

   Wolfram
