From what I can remember, yes that\'s the only thing that file was for. It wouldn\'t hurt to put it back in, else everytime you boot the PC with the CD in (if it\'s set to boot from CD first) it\'ll start the WinXP install. With the file there, it sees if there is an OS already on the drive and if so, prompts you to press a key, if not then it goes straight to the install.
