dvd and eth0 doesnt work on fresh install mdk 10.1


Ok. I''ve just installed mdh 10.1 community. But i don't know what's going on with my dvd reader and my eth0 device.

First, the DVD.
I've installed the OS from 3 cds using my dvd reader. Setup runned smoothly and with no problems. I restarted and logged into KDE. Then i see that /mnt/cdrom was shown with the hard disk drive icon. I double clicked it and an error message poped up sayin that device /dev/hdc doesnt exist. Checked /dev and, as reported, the device isn't there. I had NO problems gettin my CD Writer recognized.

Something similar happened when i first installed MDK 10.0 Official. But, i tried booting with an alternative kernel that install putted into the LILO list and like 'magic' the dvd started to work. I see no alternative kernel in this version, so i don't know what to do and my entire backup is in a dvd.

I have a LG DVD reader and CD Writer.

Next, the eth0 thing
Here i have NO Idea what can be happenning. This is the first time i have 2 network interfaces since i want to share internet connection: eth1 is a VIA Rhine II interface, no problem with it, eth0 is a DAVICOM (CNET) card, i've tried to configure using drakconf and manually editing the eth* scripts. Nothing works. When network starts at boot time it just appears [FAILED]

Thanx in advance.

dmesg | more

and look to see how the kernel recognizes and configures your DVD drive.

Try dmfe for the Davicom chipset

edit /ect/modprobe.conf

change "alias eth0 tulip" to "alias eth0 dmfe"

reboot

Ok.. eth0 is up... but dvd ...

Ok.
Thanx SinSpinr, eth0 is up and running.

opjose, the result of dmesg | grep 'CD' is

hdd: HL-DT-ST GCE-8160B, ATAPI CD/DVD-ROM drive
hdd: ATAPI 32X CD-ROM CD-R/RW drive, 2048kB Cache, DMA
Uniform CD-ROM driver Revision: 3.20

Check out that both devices, the dvd and the cd-rw, are mapped as hdd, and i think this could be the problem. How can i create or force the system to create an hdc device and map it to my dvd? I've just checked the jumper settings of both drives and they're ok, the cdrw is slave and the dvd is master, they're on the same channel IDE1. I have 2 hard drives at IDE0, no problem with them.

Anyway, here's my entire dmesg output. Thanx again

This is probably why:

Probing IDE interface ide1...
ide1: Wait for ready failed before probe !

The drives are not going ready as far as the kernel is concerned.

This could be due to a noise issue on the cable (change cables and route them away from the CPU and motherboard as much as possible, shield them with metal if possible... e.g. the casing, etc... DO NOT use "round" cables...).

This could also be due to booting the system with a disk in the drive(s), data rates being set to high by the bios, etc.

Start by setting the drives to PIO 3 mode and see if there is any change.

same thing

Changed to PIO3
nothing
Changed Cable
did not work... :S
under Windows it all runs fine. and as i said, i booted and installed from the dvd reader, the one with problems
anything else would be appreciated.

While Windows is often used as a comparison, remember that the results from Windows don't necessarily apply.

As Linux sees it, your devices are not coming "ready" when the IDE interface is probed and reset.

USUALLY this indicates a problem with the devices themselves or with communication to/from the device.

I say USUALLY because an unusual kernel problem may also be to blame, but this is less likely...

It may be possible to pass a kernel parameter to Linux prior to start to help deal with this and assign the correct mappings.

Quick question here.
Is their a problem with noise and rounded cables ?
I put some on my system to help with the airflow. I haven't heard anything negative about them yet.

I was just wondering..........

Never hurts to keep your ears open and ask questions <grin>

Thanks Charlie

Rounded cables put the wire pairs next to each other in a way that the ribbon cables do not.

This causes signal induction, where in an adjacent wire picks up a signal from another, called cross-talk.

Most rounded cables have had their individual strands cut apart negating some of the RF shielding features of the return ground on the 80 pin versions.

The rounded cables then tend to pick up far more interference from the CPU and other components as well.

If you really want to use round cables they should not be hacked apart ribbon cables or loose stranded, but rather specifically designed for this purpose... e.g. w/twists in the manner of cat-5/6e and with an outer shielded shieth.


I at first thought that the caveat about round cables was all hype, until I noticed problems burning DVD's on a particular 3.4gHz P4 system I had.


I ended up replacing everything in the system trying to eradicate the problem.

New motherboards, software, OS installs, power supply case, everything, but I kept the same type of round cables (though I did swap them for a different set...) EVERYTHING.

The same problem continued even though it was seemingly impossible given the completely revamped machine...

Then one day I put in a set of flat cables and routed them away from the mainboard while bending/folding them up against the new case sides.

The problems went away immediately.

I couldn't believe that the cables could be to blame so I tried a couple of different pairs from other manufacturers. One rounded set gave me decent results, another the same problem as before.


Finally I scoped the signals on a fast Tek scope.

Sure enough on some of the rounded cables noise induction could be seen as well as more than expected "ringing".

So watch out.

Not all rounded cables are bad, but some are much better than others.

nothing works... with the dvd

ok, everything's well connected, i have read faqs ant done everything opjose said before.
I compared to windows to discard device failure., and as i said, everything's works fine there.
so... any other idea to get my IDE1 well identified?
As i said, when i first installed mdk10official, i had the same problem but once i booted with other kernel included with that version (the one labeled as 'linux-smp' on the LiLo boot menu) everything started work fine, even if i booted with the normal 'linux' kernel. That makes me think i have one kernel module missing to handle the IDE the right way. My motherboard is an Shikatronics model SHP4VQF24S and uses a VIA PM800 + VIA 8237 Chipset
thanx again

It's unlikely that it's a missing kernel module, as the ide interface modules are rolled into the initrd image for that kernel....


However it could well be the initrd image itself which is to blame.

After you installed the smp kernel, the process may have created NEW initrd images, cleaning up the problem.

Any time you modify the boot themes and kernel parameters a new initrd image is automatically created for you.

Question Info on initrd, boot theme, etc.

Thanks again opjose...
well... this is kinda new for me. I've never dealed with boot parameters and initrd images... where do i find information (online or printed docs) about this so i can try to fix this problem. Serious, I have no idea where to start.
Thanx again

Basically the way it works is like this...

initrd images are stored in /boot

They are used to "preload" any modules along with the kernel, so that once the kernel starts to run, it has sufficient resources available to it, to find the hard drives and continue initialization of the system.

Usually the initial installation merely copies out the contents of an initrd image to the /boot directory which is used during the first stage boot.

When you subsequently load a new kernel via urpmi or rpm, the installation wants to see what you may have manually added to your system (such as a raid array) so it builds a NEW initrd image for the new kernel you are installing.

When it does this it uses the entries in /etc/modprobe.conf and /etc/modules.conf to determine which drivers to add to the initrd image.

Programs such as the bootsplash and lilo gui's will automatically do this for you as well... but you can also do it manually.

For example; if your SMP kernel is working and up and running, but you want to generate a new initrd image for the uniprocessor kernel... and you have kernel-2.6.8.1-12mdk, all you would have to do is type as root


mkinitrd /boot/initrd-2.6.8.1-12mdk.img 2.6.8.1-12mdk

where the /boot/initrd-2.6.8.1-12mdk.img indicates the name of the file it is to create (in this case it should already exist and ask you if you wish to overwrite, to which you answer YES...)...

and 2.6.8.1-12mdk specifies which kernel modules are to be used, in this case namely those from the UNIPROCESSOR 2.6.8.1-12mdk installed kernel.

After it succeeds (you merely get a prompt back after the overwrite message...) you need to run lilo again to get the boot loader to recognize the changes.

The mystery of dvd and ide1

Aright. The mystery remains...
Today I turned on my computer and suddenly i found i had access to my dvd.
My motherboard usually doesn't start up if i have any USB device plugged in but this didn't happen today, booted up normally and when i got my deskop loaded i found the dvd correctly configured.
Now, the ONLY thing i did was installing an trying to configure the demo version of vmware up and running. I haven't run any virtual machine yet.
I'm surprised and really curious about what vmware did. Maybe it's because it does something with the rd scripts. That reminds me what opjose told me about the init images.

At the end... this never happened to me with MDK 9.x but 10.0 and 10.1 has got me this problems and, beside, i find the 10.x versions buggy compared with 9.2 so, now i'm near of holydays i'm thinking about give Debian a chance (i'm downloading the latest version) .

Any suggestions? can anybody tell me about that?

thanks!
