Getting the Firmware
--------------------
The firmware can be found in the software update zip files on this page:
http://www.hauppauge.de/sw_dec.htm

The firmwares are named as follows:
DEC2000-t:	STB_PC_T.bin
DEC2540-t:	STB_PC_X.bin
DEC3000-s:	STB_PC_S.bin

Note that firmwares since version 2.16 beta2 for the DEC2000-t give the device
the USB ID of the DEC3000-s.  The driver copes with this.

Instructions follow for retrieving version 2.16 of the firmware:

wget http://hauppauge.lightpath.net/de/dec216.exe
unzip -j dec216.exe software/OEM/STB/App/Boot/STB_PC_T.bin
unzip -j dec216.exe software/OEM/STB/App/Boot/STB_PC_X.bin
unzip -j dec216.exe software/OEM/STB/App/Boot/STB_PC_S.bin


Compilation Notes for 2.4 kernels
---------------------------------
For 2.4 kernels the firmware for the DECs is compiled into the driver itself.
The firmwares are expected to be in the build-2.4 directory at compilation
time.

mv STB_PC_T.bin build-2.4/dvb-ttusb-dec-2000t.fw
mv STB_PC_X.bin build-2.4/dvb-ttusb-dec-2540t.fw
mv STB_PC_S.bin build-2.4/dvb-ttusb-dec-3000s.fw


Hotplug Firmware Loading for 2.6 kernels
----------------------------------------
For 2.6 kernels the firmware is loaded at the point that the driver module is
loaded.  See linux/Documentation/dvb/firmware.txt for more information.

mv STB_PC_T.bin /usr/lib/hotplug/firmware/dvb-ttusb-dec-2000t.fw
mv STB_PC_X.bin /usr/lib/hotplug/firmware/dvb-ttusb-dec-2540t.fw
mv STB_PC_S.bin /usr/lib/hotplug/firmware/dvb-ttusb-dec-3000s.fw
