I've been following the "ultimate unattended xp cd" guide to install make a CD that will install Windows XP with the client programs that we use. The program uses install shield so I'm pretty sure I can do a silent install by running "start /wait %systemdrive%\CPO2004client\Setup.exe -s" (I already created the setup.iss file and created the CPO2004client folder in the $1 folder. Where do I put the "start /wait %systemdrive%\iCPO2004client\Setup.exe -s" command to get it to run with the windows setup, is it in the winnt.sif or somewhere else?
