what should i do??? plz help as i have important backup files on my cds which i need to work on badly...
---------
secondly the problem is my mouse and keyboard.. my mouse is working fine except the rolerball.. i have added the Zaxis command in the config file that the desktop installtion manual tells me 2.. still no effect.. and to make things worst.. my keyboard only works to acceptable level when in the keyboard layout switcher i deselct the gnome default keyboard.. but i have to do this everytime...

| You can mount the cd automatically by specifying it in /etc/fstab, using FS type iso9660. Not sure about your keyboard. |

my fstab config reads like this:
| Code: | | /dev/hdc1 /boot ext2 noauto,noatime $/dev/hdc3 / reiserfs noatime $/dev/hdc2 none swap sw $/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro $ |
so i think that it is already including.. i think my problem is that i don't know how to acces the cd drive... were do i go to access it.. assuming its already mounted?

Um...from that, it would seem that /dev/hdc is your hard drive, not a CD drive. Also, notice the "noauto" in the /dev/cdroms/cdrom0 entry. This means that it just isn't mounted at boot time. Type this to mount it anytime:

Ask this in the Desktop Env forum, you might have better luck...
As for the mouse make sure you have the protocol as ImPS/2 in your XF86Config

As Lews_Therin told you, /dev/hdc may be your main HD
But I don't get what are the $ in your fstab.

You most likely didn't include cdrom support in your kernel.

The mount point is the directory in your filesystem where you want the contents of your mounted cdrom to show up. Under unix, the standard location is /mnt/cdrom, but it can be anywhere you want.
The same goes for any mountable filesystem wether it's a disk partition, floppy, usbstick or a Samba share.
After it's mounted you can accres the files there as you would with any other file on our system.
You might also consider adding the option "user" to your fstab, so normal users can mount cdroms too.
The line would then look like this: | Code: | | /dev/cdroms/cdrom0 /mnt/cdrom iso9660 ro,noauto,user 0 0 |
hope it helps.

"mkdir" won't screw anything up.
its evil twin "rm -r" on the other hand...

One time in the old days when I thought that the Linux symbol was a light orange-red hat, I did "sudo rm -r /usr" since I didn't think anything important was in there.
Let's just say that it was not fun.

Looks like you're using nano and this just indicates line continuation off screen. |

| Hopefully I understood your post. You have the CD mounted and you're confused as to why the eject button on the drive does not function. You will have to make sure the drive is un-mounted before it will eject. When mounted the eject button is disabled. Did you specify the "noauto" option in your fstab? Does mount report that the drive is currently mounted? You may want to check out "man eject" for related information, and of course the man page for mount. |

after you're done with whatever you're doing with your cdrom just do
Then you can eject your cd, also try looking into supermount since it's easier for you to use. |

Sounds great!
I once did strip /usr/lib* in an misguided attempt to save HD space. Almost the same effect as rm, but it gives much more scaring error messages and generally very sublte failures

Easier: do
which will umount your cdrom and then open the cd lid Also sooo much geekier

Supermount is very good and really easy to configure: If you have it compiled into your kernel, simply change the cdrom-line in your fstab from:
| Code: | | /dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro |
to:
| Code: | | none /mnt/cdrom supermount fs=iso9660,dev=/dev/cdroms/cdrom0,ro,users,auto 0 0 |
Now there's no need to mount/umount your cdrom anymore. To "mount" it, simply access it (e.g. cd /mnt/cdrom or ls /mnt/cdrom). To eject the drive, simply press the eject button (like in windows).
But I recommend that you learn how to use mount and mkdir before compiling your own kernel

hey a quick question about supormount.. in my fstab...
like i only have 4 columns rite.. fs, mountpoint, type and opts
u said: | Quote: | | none /mnt/cdrom supormount fs=iso9660,dev=/dev/cdroms/cdrom0,ro,users,auto 0 0 |
from my understanding of what u said:
/mnt/cdrom is the mount point
supormount is the type
ro,users,auto is the the opts
is fs this?: "fs=iso9660,dev=/dev/cdroms/cdrom0" do i need to type "fs=" and but a comma after cdrom0?
what r the 2 "0 0" at the end.. and the "none" in the starting....

no, you (should) have six. If you use nano, scroll right in the line where the $ symbol is, you should see the parts that are missing.

(Man, I just changed my .sig two days ago )
You are partially right. Supermount is a special case, lets look at the usual line first:
| Code: | | /dev/cdrom /mnt/cdrom iso9660 noauto,rw 0 0 |
The first field is the linux "special device", and interface from the kernel to be able to access hardware devices. It basically tells the kernel where to look for the hardware you want to mount.
The second field is the mount point allright, I already explained above what that does.
The third field is the filesystem, specifying how the kernel should read the data coming from the hardware device.
Now the fourth field is interesting. It contains "mount options". They tell the program handling the filesystem some parameters on how exactly do that handling. You can read about them in the mount manpage (man mount) These are highly dependant on the filesystem used, kind of device used etc., but some of them are generally available, like the one in the example above.
You can string together all kinds of mount parameters in this field, separating them with commas.
"ro" means read-only, and it is not strictly nesessary for a CDROM as it cannot be written to, but it keeps the mount command from issuing the "read-only filesystem found" message at every mount.
"noauto" means it should not be automounted at boot.
The fifth field is called "dump" and is meant to be used by a program called dump and is part of the old UNIX heritage. Linux does not use this field at all AFAIK, so ignore (but not omit!!) ) it.
The last field is relevant only if you do an unclean reboot, when your filesystems will be checked for consitancy. AFAIK, Gentoo does not use this field, it handles checking differently in its boot scripts.
Now lets look at the supermount line:
| Code: | | none /mnt/cdrom supermount fs=iso9660,dev=/dev/cdroms/cdrom0,ro,users,auto 0 0 |
[NOTE] I have never used supermount, so I'm partially guessing here how it handles things.[/NOTE]
The element is none, because the mount command does not deal with a real device here, supermount does. If the device is "none", it assumes the filesystem handler will know which data to use.
Mount point is as usual, as are the last two fields.
"supermount" as a filesystem basically causes mount to ask the kernel "hey, I've got a filesystem called supermount, do you have a program which understands this?" and the kernel replies "hmm, yes, a program called supermountd told me it could" at which point mount hands control over the data over to supoermount, which starts to do its magic.
mount options: ro,users,auto are generic options.
fs=iso9660,dev=/dev/cdroms/cdrom0 are options which only supermount can understand, and they obviously tell him the device to use and the filesystem, just as a normal line in fstab would. But as supermount can do much more than just CDROMs, it needs to be told this here.
Phew, that turned out a lot. But now that you've already read as much you might just as well read on and look at the man pages for fstab and mount.
*bows*

sorry, I had a typo there (also corrected in my original post):
| tuxlover wrote: |
| Code: | | none /mnt/cdrom supormount fs=iso9660,dev=/dev/cdroms/cdrom0,ro,users,auto 0 0 |
|
should read
| Code: | | none /mnt/cdrom supermount fs=iso9660,dev=/dev/cdroms/cdrom0,ro,users,auto 0 0 |
But maybe supermount is so good it's actually supor
And nephros, your post sounds like a good explanation. Too bad supormount isn't covered in man fstab  |

Oh wow, my bad. I was thinking /dev/cdrom didn't exist. Sorry about that.
