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
./get_dvb_firware 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).
