+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).
