how do i enable ide-scsi for my cd burner


Ive been tyring to get my new cd burner to work with redhat 9, and k3b and im having some problems. when i open up k3b it says "cdrdao 1.1.7 does not suppport ATAPI" and it tells me to enable ide-scsi. this is probably a simple question, but im kinda new to linux so im not real sure what to do. thanks for your help!

I think you may be able to solve this by putting a line into lilo.

Below I have written a sample for you to look at. The line you should put in is the one that says append. Replace ' hdc ' with whatever your cd-rw is.

Let me know if this works.

image=/boot/vmlinuz-2.4.19-ac4
label="Linux
read-only
append="hdc=ide-scsi"

What Distro are you using? Do you have Grub or LILO?

Peace,
Whitehat

Yes - you can pass kernel parameters from GRUB or LILO - add it to the end of your kernel line in grub.conf -so it will just be hdx=ide-scsi on the end of that line - check in dmesg for the correct device name....

alright, well heres what i got, it doesnt look to good though. did i do it wrong?

Code:
[root@localhost /]# cdrecord -scanbus
Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J?rg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
[root@localhost /]#

looks like the scsi driver is not being loaded ( I think)... any reference to hdc in dmesg with the new grub setup ?

dmesg | grep hdc

see what that that tells you, also look for any any reference to ide-scsi in dmesg...

cdrecord -vv -scanbus may give more info as well. I'm not sure if that one will work as I'm sitting at my mac right now. :-)

i could be wrong, but:
unless you enabled scsi emulation for your cdrom in the kernel, you cannot treat your cdrom as a scsi device just by adding that line to the bootloader.

also, scsi devices will not point at /dev/hdXXX, they will point to /dev/sXXX (unless of course, you're redirecting twice). most likely doing an "ls -l /dev/cdrom" will point you to /dev/hdc, while it sshould be pointing somewhere to /dev/srXXX.

i don't think you can burn CDs using ide on the 2.4.* series kernels.
this is possible only in the 2.6.0 kernel that just came out.

no:

burning can only be done by treating your IDE as a scsi device
make sure you kernel has been compiled w/ scsi support.

Unless you want to take Berhanie's advice and upgrade your kernel to 2.6

Hello,

Having a few problems with this too. For me i had to add the append= line at the beginning of lilo before the boot device and then it enabled scsi emulation no problem. But i still can't burn as a user yet. I hope to get it worked out today.

See the following links --and search the slackware forum using "k3b" quite a few posts about this and how to tell if you have the scsi drivers already too.

Hope this helps::: the first link tells how to append grub and lilo

Peace,
