frontend stv0299.


in my /etc/modprobe.conf (SuSE 9.2)

#Skystar 2 B2C2 Flexcop

options dvb-core dvb_shutdown_timeout=0
alias char-major-250 skystar2
install skystar2 { /sbin/modprobe stv0299; } ; /sbin/modprobe --ignore-install 
skystar2
remove skystar2 /sbin/modprobe --ignore-remove --remove skystar2 && 
{ /sbin/modprobe --remove stv0299; }

in my /etc/modules.conf (SuSE 9.0)


#Skystar 2 B2C2 Flexcop
