Permanently sharing iBook CD drive to Windows machine

I have a network connection to a Windows machine and wish to share the CDROM from my ibook that is running OSX 4.5. I can do this using 'sharepoints' by changing the details every time, but would like a permanent solution. Does anyone know the file path to use for the drive in my Samba configuration?
Thanks,
Glen.

If it can help, each time you mount a CD or a network drive, they appear in /Volumes on your HD, which is a hidden folder. Maybe if you set an alias to it (actually you may need a hard link for this - looo at man ln in the Terminal) in a place such as the user folder you share...
