You can use something like
ISO Recorder v 2 to create an image of the cd on your PC - then copy that image to either your portable HD or USB Key and then use something like
SlySoft Virtual CloneDrive installed on your netbook to mount the image and access it as a virtual cd/dvd drive.
The above will work if you have Windows on the netbook - if you have linux on your net book you will have to find an equivalent to virtual clone drive for your OS.
