But, If i unterstand you right then you add this line in your "risstndrd.sif". Do you put the line then under [unattended]? I'm also new to the slipstreaming thing. I have a default "XP_X86 SP2" cd (I 've used it for my RIS Image) and I would like to slipstream SP3 with my RIS-server. But has anyone a foolproof howto for doing this?
