Autoinstallation Procedures

Hi All I am new to suse auto-install. Please direct me to the link where I can find step by step procedures to setup the autoinstall server and creation of boot floppy. I tried setting up an autoinstall server and also created a boot floppy, but, while boot through the floppy at a point it "Can't find the Source of Installation" and starts the manual installation. I think it is not loading the network card drivers, so it is not able to find the source. Thanks and Regards Umesh
