Gentoo not seeing DVD Drive

I'm running Gentoo Linux on my Sager NP9261 which has a "DUAL Pioneer Combo 8x8x6x4x Dual Layer DVD +/-R/RW 5x DVD-RAM 24x CD-R/RW" and from what I can find it's a DVR-K17. Obviously the DVD drive shows up in the Live CD and it also shows up under Windowz but when I but into my Gentoo installation it isn't there.
Just wondering if anyone had any ideas on getting it to detect and use.
Thanks

 

So... you can't see it when there's nothing in it?
Does it still work if you put in a CD/DVD?

 

LOL! Even if there's something in it of course. I'd be a bit worried about my mental state if that was the problem. CD's DVD's nothing detects. I noticed that when I was installing Gentoo that it was on /dev/hda. But hda doesn't exist. There isn't anything hd* at all in /dev/. Nor dose /dev/cdrom exist. Also there isn't anything but my single hard drive under serial. /dev/sda.
I do remember when I was running Ubuntu that it was under /dev/sdb and that during the installation of Gentoo lspci saw the drive as a serial device.

Edit: also lspci dose not see it in the fully emerged system.

 

I find that my hard drive and cd drive is found under /media, check there.
You may also need to update/install a more recent kernel.
Other than that, I don't know, you should check with John B since he definitely knows more about Linux than me.

 

Do you have /dev/sr0 ?

 

For the /media the DVD drive isn't even seen as hardware so there wont be anything mounted yet. Also I have the latest stable kernel the gentoo-sources has to offer.

Nope no /dev/sr0

 

Could you post the output of dmesg | grep DVD ?

 

No output from the DVD. (Ah love grep)
Being that there's no output and I don't see anything dangerous to me to be posting I'll attach a whole dump of what dmesg gave me.
LOL it made me put .txt at the end...

 

Could you type lsmod and post the output?

That is as root.
Also I never expected someone to respond so fast and thank you too!

 

It's a pleasure

Try modprobe ata_piix

 

FATAL: Module ata_piix not found.

 

And modprobe piix ?

 

Same thing. Any idea where that is located in make menuconfig? I could try rebuilding my kernel with that set as a module. I'm google'n it now.

 

Have you compiled the kernel?

 

Yea. It's a custom one right now. Though the first time I installed Gentoo I used "Gen-Kernel" and it didn't show up so it seems that not even Gen-Kernel built it in. Heh this things fast. ~10 min to build it!

 

I'm not an expert with that but it seems some modules are missing...

Take a look there: http://www.thinkwiki.org/wiki/Problems_with_SATA_and_Linux#DVD_drive_not_recognized

 

Thanks. I'm working on that. I was trying to boot to Ubuntu to see what was loading in it but I have to burn a new CD for it (Yay for having extra PC's).
That link has a lot of good information!

Edit: Him... Wheres the +Rep button...

John's right. You are probably missing the ata_piix, or sometimes called around here, piix support. I have a current laptop too, (Asus V1S), and the way I was able to recognize my optical drive was to make sure I either built the Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support, (more commonly known as ata_piix, because that's what the module is called), into the kernel or build it as a module. To make sure you have this support configured into your kernel do the following as root, (I'm going to assume you are going to /usr/src/linux and typing make menuconfig to build your kernel configuration and not editing your /usr/src/linux/.config file directly);

Code:

cd /usr/src/linux
make menuconfig

Then you need to use the menu for Linux Kernel Configuration and go through the following choices. Device Drivers --> Serial ATA (prod) and Parallel ATA (experimental) drivers --> and then make sure that the Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support selection is either selected with an asterisk (*) which means the support will be built into the kernel, or with an M (M), which means that you will build the support as a module. Then finish your kernel building and installation process by doing the following from the /usr/src/linux directory;

Code:

make && make modules_install
cp /usr/src/linux/arch/i386/boot/bzImage /boot/[whatever you name your kernel]
cp /usr/src/linux/System.map /boot/[whatever you name your System.map]
cp /usr/src/linux/.config /boot/[whatever you name your config file]

You also may want to backup your existing kernel, System.map, and config files you have in /boot, by renaming them to [their name].old or something like that. BTW, if it matters to you, I would recommend building the support into your kernel and not building it as a module. My reasoning is that I like to build modules for things that can be taken off of my laptop, and building support into the kernel for stuff that can't.

However, if you go the module route, you will need to make sure that the module is loaded either automatically via udev, (which it was for me), or manually through adding the module name, ata_piix, to your /etc/modules.autoload.d/kernel-2.6 file. I would recommend after building and installing your kernel, to just reboot and see if your optical drive is found, because the module should autoload. If it doesn't, open a terminal window as root, and do another lsmod to see if ata_piix is loaded. If the module did not autoload, then modprobe ata_piix again, and this time it should load the module, and you should be able to see your optical drive. Then you can edit your kernel-2.6 file as I mentioned above to autoload the module in the future.

Good Luck..

 

Him... ata_piix is already built into my current kernel. Looks like I'll have to dig around more and figure out how exactly it is connected, being that ata_piix is the driver that Ubuntu is using to run it, and the Gentoo Minimal disc too.
Thanks for the post I had no clue on where it was and figured I'd check back here before starting to dig around!

 

You need to make sure you install into /boot and then boot your system, with the newly built kernel. The easiest way to check that piix support is being loaded, is right after you boot up in Gentoo (not the install or live cd), if you open up a terminal and as root, type the following command;

Code:

dmesg |grep -i piix

you should see something like the following;

Code:

ata_piix 0000:00:1f.1: version 2.12
scsi4 : ata_piix
scsi5 : ata_piix

That will let you know that the support is being loaded. But loading that module is just part of enabling CD support in your kernel. You also need to make sure you have support for SCSI CDROM either built into your kernel or loaded as a module. Just to make sure you should see if you get anything from issuing the following command;

Code:

dmesg |grep -i cd-rom

If your CD is not being detected, you should get nothing from typing that command. If you post the sections of your /usr/src/linux/.config file between the following section headers, we can probably figure out what's up..

Code:

#
# SCSI device support
#

[post everything between these sections in your response]

#
# Fusion MPT device support
#

Good Luck..

Got some help over on the Gentoo Forums. The problem was that the "IDE interface: JMicron Technologies, Inc. JMB368 IDE controller" wasnt enabled in the kernel. Heh compleatly missed that. Complete failure on my part.
Now I know and now all my kernels are configured extreamly more minimalistic on the slower box's.
