* First, make sure that looback is compiled in your kernel or a module: 

Device Drivers  ---> 
  Block devices  ---> 
  <M> Loopback device support

If you compile the module, the module name is loop.

    * Second, copy CDs to ISO files: 

# cat /dev/cdroms/cdrom0 > icewind_dale1.iso 
# eject 
# cat /dev/cdroms/cdrom0 > icewind_dale2.iso 
# eject

Note We do not need to mount CDs. We are not copying the contents of the filesystems, we are copying the filesystems themselves.

    * Then, as root, mount the first ISO file. 

$ mount -o loop /home/steve/icewind_dale1.iso /mnt/cdrom

    * Run the winex3 installer as your user. Be sure to close all Windows applications before installing anything. 

# cd /mnt/cdrom
