Only one small thing: I don't see my CD drive !!! What should I do to MOUNT or see my CD drive??? I put a Music CD in there and no response from Knoppix. Looks like Knoppix thinks that there is NO CD drive. Sad Please Help, Marc.

Open Konsole and execute this Code: su hdparm -I /dev/cdrom does it display correct info about your CD Drive. execute hdparm -I /dev/hda or sda too. __________________ It takes a lot of time to be a genius, you have to sit around so much doing nothing, really doing nothing. - Gertrude Stein New Users: Read This First

If not, what software can I use to play MP3's??? Another question: How do I list the content of the CD?? (I'm new to the LINUX world ) Thanks for your HELP, Marc.

Knoppix supports MP3 format. play mp3 files in xmms.

you have to unmount CD first.

Code:

umount /dev/cdrom

Here's the content of /etc/fstab:

Code:

knoppix@Knoppix:~$ cat /etc/fstab
/proc      /proc       proc   rw,nosuid,nodev,noexec 0 0
/sys       /sys        sysfs  rw,nosuid,nodev,noexec 0 0
/dev/shm   /dev/shm    tmpfs  rw,nosuid,nodev,noexec 0 0
/dev/pts   /dev/pts    devpts mode=0622           0 0
/dev/fd0   /media/fd0  auto   user,noauto,exec,umask=000    0 0
/dev/cdrom /media/cdrom  auto   user,noauto,exec,ro 0 0
/dev/hda /media/hda  auto   users,noauto,exec,ro 0 0
# Added by KNOPPIX
/dev/sda1 /media/sda1 ntfs noauto,users,exec,umask=000,uid=knoppix,gid=knoppix 0 0
# Added by KNOPPIX
/dev/sdb1 /media/sdb1 vfat noauto,users,exec,umask=000,shortname=winnt,uid=knoppix,gid=knoppix 0 0
# Added by KNOPPIX
/dev/sdb2 /media/sdb2 vfat noauto,users,exec,umask=000,shortname=winnt,uid=knoppix,gid=knoppix 0 0

Here's what I get for mount -l:

Code:

knoppix@Knoppix:~$ mount -l

/dev/sdb1 on /cdrom type vfat (ro,nodev,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1)
/dev/cloop on /KNOPPIX type iso9660 (ro)
/proc/bus/usb on /proc/bus/usb type usbfs (rw,devmode=0666)
/dev/pts on /dev/pts type devpts (rw)
/dev/sdb2 on /media/sdb2 type vfat (rw,nosuid,nodev,umask=000,shortname=winnt,uid=1000,gid=1000)
