Machine is a Dell Optiplex I want to run some device-driver installations on unattended setup. These come as "Setup.exe"s for Networking, Graphics, Sound etc... So I want to include a cmdlines.txt that itself calls a batchfile to add the GUIRunOnce-Keys for the Setup.exes Like: REG ADD %KEY%\005 /VE /D "Intel Chipset Software Installation Utility" /f REG ADD %KEY%\005 /V 1 /D "%systemdrive%\dell\drivers\R162291\Setup.exe -s" /f This seems to work. My problem: I have a lot of other machines on my network, that may require re-installation. So I have different .SIFs on my RIS-Server. But to my knowledge, I can only have one cmdlines.txt - So what would be the best way to specify batchfiles for installation of different hardware requirements? Many Thanks, Reinhard
