fedora 8 doesn't detect cd/dvd on lenovo laptop
 

Hello,

I've been having difficulty this cd/dvd drive on my new lenovo y710 laptop. I am running Fedora 8, and it will not recognize the cd/dvd drive. A look in the /dev file showed no cdrom device listed. The /mnt and /media folders are empty.

I've installed a fedora 8 in dual boot with windows vista. Windows Vista will recognize the drive, but only if the windows boot loader is installed on the MBR. If Vista is boot from the grub loader, then it fails to recognize the drive.

I am not experienced with linux, so I'm hoping someone here can help. I tried installing other distributions (kubuntu and suse) of linux, but came up with the same problem. Linux will install from a dvd fine, but once the OS boots from the hard drive, the dvd is no longer recognized.

I've updated the firmware for the drive and the BIOS with no luck. Here's some more system information:

/etc/fstab:
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0

ls -l /dev:

Note: I ran the command "makedev cdrom" without knowing what I was doing. Turns out that didn't work (go figure).

I also have the lshw gui, which displays information about my motherboard (BIOS, CPU, system memory, Host Bridge), but nothing else.

Oh yes, I am running kernel: 2.6.24.5-85.fc8


I've had someone look at the machine and he's not been able to determine what the problem is precisely. Any help would be appreciated.

I would list dmesg here but I'm afraid that might go over the post length limit.

Thank you for any assistance.

Welcome to LQ!

Being unfamiliar with your hardware I can give you only one hint. Probably the DVD is connected to the IDE interface (00:1f.1 IDE interface: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller (rev 03)) and relevant kernel module is not loaded. Loading it with modprobe will probably solve the problem.

Hi Emerson,

Thank you for the response. I've had a look at the modules, but I'm not sure how to use them properly. Here is the output of an lsmod:

I didn't see any cdrom/dvd related module here.

I can do /sbin/modprobe -v cdrom:
insmod /lib/modules/2.6.24.5-85.fc8/kernel/drivers/cdrom/cdrom.ko

but this doesn't fix the problem. I am not familiar with loading modules manually, so I don't know if I've done it correctly. "cdrom" then appears in the lsmod output. Do I have to load an ide or scsi related module as well?

Secondly, if I reboot after loading the cdrom module, the system returns back to its former configuration (ie no cdrom module loaded). Again I'm not sure if I loaded it correctly.

Does /dev/sr0 appear if you load cdrom module? For autoloading modules at startup see Fedora documentation (probably you have to add it to the /etc/modules.conf).

Nothing changes in the /dev folder when I load the cdrom module.

I'll check the Fedora documentation for loading modules. There is no /etc/modules.conf file, but there is a /etc/modprobe.conf file.
