TXT VERSION

This setup works for 2.2 kernels
1. Setting up the sat card
Software you need:
1. http://www.linuxtv.org/download/dvb/dvbd3.tar.bz2
2. http://www.linuxtv.org/download/dvb/siemens_dvb-0.8.2.tar.gz


Extract the driver (2.) into folder /root/sat/0.8.2/ and the dvbd (1.) also into /root/sat/0.8.2

Compile them:
cd /root/sat/0.8.2/DVB/driver
make
cd /root/sat/0.8.2/dvbd3/
make
cp dvbd /usr/sbin/

If compile fails you must upgrade your libs and gcc

Create following scripts:

</root/sat/makeinsmod>
   #!/bin/sh
   echo -n "Loading dvb kernel modules..."
   (
	   cd /root/sat/0.8.2/DVB/driver/
	   make insmod >/dev/null 2>&1
   )
   echo "done !"
</root/sat/makermmod>

   #!/bin/sh
   echo -n "UnLoading dvb kernel modules..."
   (
	   cd /root/sat/0.8.2/DVB/driver/
	   make rmmod >/dev/null 2>&1
   )
   echo "done !"
</root/sat/Eutelsat W6>
   #!/usr/bin/perl
   open(IN,"/bin/ps ax|");
   @lines=<IN>;
   close(IN);
   @lines = grep(/dvbd/, @lines);
   if(@lines){
   		system("killall -9 dvbd >/dev/null 2>&1");
   }
   open(IN,"/sbin/ifconfig|");
   @lines=<IN>;
   close(IN);
   @lines = grep(/dvb0/, @lines);
   if(@lines){
	   system("/root/linuxsat/sat/Smakermmod >/dev/null 2>&1");
	   sleep(2);
   }
   system("/root/linuxsat/sat/Smakeinsmod >/dev/null 2>&1");
   sleep(2);
   system("/usr/sbin/dvbd -q");
</etc/dvbd.conf>
