Ok, I know how to unmount and mount a floppy drive and that you can view the contents of the floppy in /mnt/floppy and it is located at /dev/fd0, however, where is the CD drive ? how do you mount and unmount it ? Also, I have some XVID and DIVX and AVI format movies but I do not konw how to view these in linux , I have no idea what program to use of if this kind of playback comes incorporated into linux ? If anyone could recommend a program for these things and where to get it and how to install it that would be great as I am very new to linux : )

For the CD-ROM, you can look in the /etc/fstab file for the correct device name.

Most distribution have it set to /dev/cdrom (a soft link to the actual device).
Use the mount and umount commands like you would with the floppy.
As for the movie player, you can use MPlayer.
It may be part of your distribution, check your CDs.

Ok, I found http://www.mplayerhq.hu/homepage/design6/dload.html, however I do not know which one to download from there, I have slackware 9.0, do I download the source ? what is source ? does it need to be compiled ? how do i compile and install this program ? ty. Also when I put in my cd rom drive module for my laptop and changed to /mnt/cdrom and I did a ls and a ls-a and saw nothing. Does this have to do with slackware not having built in avi /divx support or ?? Does slackware ? I am confused, I did the full 2.0gb installation of slackware 9.0. Also when I tried to umount and mount /dev/cdrom it said it was a invalid block device, could that possibly be the reason behind not seeing anything in /mnt/cdrom ? I am very confused : ) How can I check if I have built in support ? If I do indeed have built in support how do I play these avi and divx : ) Thankyou !

here's a good website for compiling things from source.

note that with slackware 9 you can also install using RPM (red hat's install tool) which is simpler, but in the long run you'll be far better off doing it from source.

What type of CD-ROM do you have ? (IDE or SCSI)

If it is an IDE, use the following table:
/dev/hda => primary master
/dev/hdb => primary slave
/dev/hdc => secondary master
/dev/hdd => secondary slave

If it is a SCSI, use the following:
/dev/scd0
/dev/scd1
etc...

I don't know, how do I find out which one I have ?

I'd have to say that "if you don't know" it's a thousand to 1 odds it's IDE. However, you could look at your computer specs, you can look at your motherboard, and you can even check out something like dmesg to find out.



Cool

Yes, take a look at dmesg.
At the command line, type: dmesg

Or do a more precise search with:

What exactly does grep do ?

man grep?
