There are a couple ways to enable or disable system services at boot time in SUSE.
From the command line:
To enable a service:
$ sudo insserv SERVICE
To disable a service from starting:
$ sudo insserv -r SERVICE
You can also use YaST:
YaST Control Center -> System -> System Services (runlevel)
Select the service you want to change then click either the Enable or Disable button.
