here is what I did: Code: mkdir /mnt/cdrom mount -o loop /home/tm/Desktop/fl1.ISO /mnt/cdrom wine cmd.exe D: dir Now I see the content of the French Language CD 1. In Win Configuration window on Drivers tab, I entered D: /mnt/cdrom When I launch Rosetta Stone and try to add language file, the program still cannot find the drive D. Here is the output of mount command: Code: /dev/mapper/vg_bubba-lv_root on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0") /dev/sda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) gvfs-fuse-daemon on /home/tm/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=tm) /dev/loop0 on /mnt/cdrom type iso9660 (rw) Here is the output of command df -h: Code: Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_bubba-lv_root 143G 14G 123G 10% / tmpfs 975M 320K 975M 1% /dev/shm /dev/sda1 194M 53M 131M 29% /boot /dev/loop0 329M 329M 0 100% /mnt/cdrom Here is the output of command ls -la ~/.wine/dosdevices: Code: total 8 drwxr-xr-x. 2 root root 4096 2009-12-12 17:35 . drwxr-xr-x. 4 root root 4096 2009-12-12 17:36 .. lrwxrwxrwx. 1 root root 10 2009-12-12 17:26 c: -> ../drive_c lrwxrwxrwx. 1 root root 11 2009-12-12 17:35 d: -> /mnt/cdrom/ lrwxrwxrwx. 1 root root 1 2009-12-12 17:26 z: -> / Thanks for generous help.
