K3b problem
 

Hi,
I installed k3b on Slackware 9.0, but after i configured it, i run it and this message appeared:

No support for ATAPI with cdrdao
You will not be able to use all your reading devices as copy sources since there is at least one not configured to use SCSI emulation and your system does not support ATAPI with cdrdao.
Solution: The best and recommended solution is to enable ide-scsi (SCSI emulation) for all writer devices. This way you won't have any problems.

What does it mean?
Could anybody explain me what have i to do?
Thank you in advance.

If you are using a 2.4.xx generation kernel, such as the one that is installed by default in Slackware, then you must enable scsi emulation at boot-time (lilo) in order to burn cds at all with an IDE or ATAPI drive.

If you have upgraded to the 2.6.x generation of kernels, then you can burn cds without scsi emulation. However you need to do at as a track-at-once burn rather than disk-at-once as the aplication which burns in DOA mode, cdrdao, does not yet have the ability to work on IDE or ATAPI cd writers.

The cvs version of cdrao supposedly works with IDE or ATAPI in the 2.6.x kernel, so you can try that if you want.

I am using 2.4.xx kernel version.
The problem is i am using grub and the boot point is in Hda3 under Red Hat.

Hda1 Windows XP
Hda2 Swap
Hda3 Red Hat
Hda4 Slackware

How have i to modify grub in order to enable SCSI emulation?

Go into grub.conf and add hdc=ide-scsi to the end of your kernel line. This assumes hdc is your cd burner. In my case it was hdd instead.

I already have this line.
This is my grub.conf in /boot/grub

default=0
timeout=10
splashimage=(hd0,2) /boot/grub/splash.xpm.gz
title Red Hat Linux
root (hd0,2)
kernel /boot/vmlinuz-2.4.20-18.9 ro root =LABEL=/ hdc=ide-scsi
title Windows XP
rootnoverify (hd0,0)
chainloader +1
title Slackware
root (hd0,3)
kernel /boot/vmlinuz-ide-2.4.20 ro root=/dev/hda4 hdc=ide-scsi

Do you have any other optical devices?
Enable scsi emulation for them too: 'hdd=ide-scsi' (assuming it's on Secondary master). Ex:

Thank you very much aaa
K3b seems to work correctly now.
Can you also tell me why i get this message when i try to mount a CDrom

mount /dev/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
