Strange dvd behavior

[gugus]

I had the following incidence when I was installing the nvidia driver:

- first I installed the fedora core 4 from a DVD
- then I installed yum as suggested in section "How do I enable 3D support for my nVidia graphics card in Fedora Core 4" on the fedorafaq.org
- then I have tried to the following command:
yum install nvidia-glx kernel-module-nvidia-$(uname -r)
but this didn't work because of some dependency errors.
- then I executed only
yum install nvidia-glx
which installed everything needed for the grhics card plus a new kernel. But the Security Keys (GPL) were not correct, I ignored that and installed the packages anyways.
- during the next reboot I was asked for the root password which I typed in without thinking too much. I was asked something like: Need root password for the requested hardware adjustment (but i don't remember the exact words).
- The graphics card and everything works fine now, but ever since the DVD drive is not recognized anymore! Also the BIOS setup program that can be start right the computer is switched on also says that there is no dvd drive connected (but it should be correctly connected, since i used it to install Fedora!)

Here are my question:

- Can it be that the nvidia and kernel packages I have installed were virus infected?
- Can Linux somehow tell the bios that there is no DVD connected? If yes, how can I undo that?

Please post a copy of /etc/fstab

Can it be that the nvidia and kernel packages I have installed were virus infected?
Absolutely, no.
For the dvd drive see
dmesg | grep -i dvd
and check the hardware browser.
Why do you say that the drive is not recognized anymore? How did you try to use it?

plus some partition are mounted per nfs

... but already the boot utility does not see dvd anymore ... I cannot boot from a dvd/cd!

[gugus]

dmesg | grep -i dvd

does'nt do anything

dmesg | grep -i dc

gives the following message:

what does that means? it looks like there is something, doesn't it?

dmesg | grep -i dc
Do you mean "dmesg | grep -i cd", right?
Well, it seems that the drive is dead. :eek: The only hint I can give here is to check the cables: could it be that you have unintentionally disconnected the power or the data cable? Can you check with another drive?

"I cannot boot from a dvd/cd"
Is the dvd drive listed in bios,can you open the dvd .

[gugus]

yes I meant

dmesg | grep -i cd

I have checked the cable serveral time. The LED also flashes, when I put in a CD ... but then nothing happens.

Do you know why the kernel asked me for the root password to fiddle around with my hardware during the boot up? is that a normal procedure when the nvidia drivers are installed .... i never had to do this when I have installed previous versions linux!

I don't think it is listed! How can I check that?

I can open it with the button ... yes, and LED comes on after I close it again!

My dell normally lets me choose the boot devices when I press F12 during the boot ... but there the dvd/cd rom is not listed anymore!

I dont know how to get into bios on Dells but on my system you press the delete key after turning on computer. For fedora or any operating system the dvd must be installed in the bios, Sorry i cant be anymore specific ,

Thank you for the information

Currently I can't reboot my computer but I will try to get into the bios asap.

Thanks again
