2.6 Kernel, CDR/DVD combo - need help.
 

Hello all,
I recently upgraded my fedora core1 distro on my Compaq Presario 2110 Laptop to 2.6-test9. (ACPI and PCMCIA work a lot better.) However, I lost DVD/CDR combo functionionality. I know there was some buzz about going to ATAPI for these devices over SCSI emulation, but I am not sure what to do. I have my kernel config'd the same as the 2.4.21 kernel that came with core 1 with respect to CD/DVD/SCSI emulation and grub, but it doesn't work. Can someone recommend kernel, fstab, and/or GRUB settings to bring the DVD/CDR drive back to life?

Thanks in advance.

Hi.

You'll have to go through the configuration for your new kernel - 2.6 doesn't require SCSI emulation for CD-R support (at least not in 2.6test11).

There's some notes either in the configuration help screens or in the README that comes with the kernel. I don't have access to my Linux box at the moment so I can't be more specific.

same here
 

Me neither (access to my box). I will check tonight. Does it work for you? Did you have to change mounting options in fstab/bootloader?

Hi.

Yeah, I got test11 to work. I removed hdc=ide-scsi in the kernel arguments.

You might want to upgrade to the latest cdrecord, as this can use the ATAPI device drivers for writing to CDs.

Have a look at this:

It might give you some clues.

It worked with removing the ide-scsi thing. Many thanks!

Yeah, scsi-emulation is broke in 2.6.0, according to this doc:

If you need cdrdao with read support for non scsi/scsi emulated drives, then grab the latest CVS off sourceforge and compile/install it.

Thanks.
 

Yeah, k3B said cdrao was not supported. Thanks. Too bad someone doesn't RPM that sucker and put it on freshRPM's. Got Ogle and Xine working for DVD playing though.

Hehe..Well if you want to grab the CVS, then you can go about it this way. Move into the directory where you want to store it, /usr/local/src for instance, then run this command:

cvs -d:pserver:anonymous@cvs.sf.net:/cvsroot/cdrdao checkout cdrdao

That will download the entire CVS tree and place it all in a directory named cdrdao, assuming of course that you have cvs installed on your system. Move into the cdrdao directory and run "./autogen.sh". This will create a configure script for you. Then just configure it with "./configure", with whatever options you want and then run "make". If everything builds correctly, then use rpm to uninstall your installed version and then run "make install". Isn't that bad. :) It will be installed in /usr/local/bin by default, else you can put it where you want using the "--prefix=/yourpath" flag when you configure it. ./configure --help will show you all the available options.

wow...
 

Do you have any idea how much time you just saved me by explaining that? Given that I only have a couple hours a day max to work linux stuff, it would have taken me weeks to research enough to do this. (Assuming it all works.) Thanks a ton! Your post is a keeper.

Your welcome...Glad I could help.
