Hi I want to make an unattended windows XP installation cd that after first boot will run a batch file i wrote which generated, eventually, a winnt.sif file on floppy (or ram drive, i haven't decided yet) then continue the setup with my answer file. my question is: how and where do i need to put my batch file to run before setup will start ? and how do i tell setup to use my new winnt.sif file ? Avi
