ide-scsi to ide-cd

quietguy47 · 05-13-2006, 07:13 PM

What do I need to do to switch from ide-scsi to ide-cd?
I'm using 2.6.14.7

If you are using 2.6.x you usually don't need ide-scsi, since this kernel knows ATAPI. Just stop passing the bootparam (edit /etc/lilo.conf).

when I do that I get "/dev/cdrom is not a valid block device"

What's the output of "cdrecord -scanbus" and "ls -l /dev/cdrom"?

I have to write :
cdrecord dev=ATAPI -scanbus

To get that to work.

Hi,

If you are having trouble with your kernel recognizing the device(s) then pass;

Code:

append= "hdc=ide-cd hdd=ide-cd"

by placing the append in your 2.6.14 stanza of the lilo.conf file.
Be sure to run lilo to update.

The new 2.6 kernel do use ide-cd module and the ide-scsi is deprecated. You can place the append for the ide-scsi in the stanza of the 2.4 or earlier to allow the use of that module.

Patrick has a thing wedged in the init scripts to load ide-scsi. You'll need to kill it off (or simply delete or don't build the module anymore--it's really not needed for 2.6.x). Once ide-scsi is loaded, unless you've told it otherwise, it will claim the IDE optical drive for itself and then ide-cd can't get at it anymore, leading to the device error.

append="hdc=ide-cd" doesn't work. It's not compiled as a module. It's compiled into the kernel.

Hi,

The append command passes the option to the kernel! The ide-cd can be a module or compiled and the option is still passed. This way you can do some reassignment of the device.

I have added append="hdc=ide-cd" to lilo.conf and updated lilo after(/sbin/lilo).
This is what cdrecord --scanbus returns

i hope u didnt mention your main aim!!!
do u want to burn cd or read cd???
you still cant write cd even using k3b??

burning cd you dont need scsi emulation(dont need to append lilo), now have you enabled that in yur custom kernel, while compilation?? (while compilaiton there is am option like that)

so you only need to give the device name not the dev=0,0,0 names

how many cd drives u have?
1. first determine the cd device, then we can get into next step
"dmesg |grep CD"

regards

No, can't burn cd's

You want to burn cd's use kuser to add yourself to the disk and cdrom group than run k3bsetup to fix permissions.

Thanks, that worked.
