It depends what runlevel you want it to start at. Go into 'file manager - super user mode' ( k menu > system > file manager > file manager - super user mode).
Navigate to /etc/init.d/
within this folder find the runlevel (possibly rc5.d, this is when the graphics server starts on suse systems)
If you are using konqueror press F4 to get a konsole window up and you should see
<machineName>:/etc/init.d/rc5.d #
at this prompt type
ln /path/to/program/you/want/to/boot programName
A pointless example would be to run ifconfig
Code:
ln /sbin/ifconfig ifconfig
If you are unsure where the program you want to start is located type
This should tell you where the program is located. Hope this is of help
