oh I see. Thank you

Thank you for your reply. BTW, may I ask one more question? If I set OemPreInstall = 0 and run the hotfixes directly from the CDRom, would it reduce the installation time?

What I know is as follow(pls tell me if it's incorrect): %systemdrive% points to the drive letter where the winxp is installed. %systemroot% points to the windows directory Since I don't want to copy the files in the directory $oem$ to the Harddisk, I want to run the Batch files: "hotfixes.cmd" & "applications.cmd" directly from the Installation CD. I think it would save some space. My question is: Is there a path which looks like %xxxx% pointing to the Drive Letter of the installation CD? Or how could I find the path of the source CD in a Batch file? Thanks in advance!
