IDE CD burner under 2.6.2

Shade · 02-25-2004, 12:20 AM

I've read about how ide-scsi emulation is deprecated in the 2.6.x series, and that ide-cd or ide-cdrom is to be used instead.

How does one go about getting the cdburner to work without scsi emulation now?
I also could not find an ide-cd or ide-cdrom module to be enabled in the kernel config.

I've tried the following:

append="/dev/hdd=ide-cd"
and
append="/dev/hdd=ide-cdrom"

in lilo.conf

A cdrecord -scanbus still won't recognize a device.

What am I forgetting

You should be able to just enable ATAPI cdrom support in the IDE section of the kernel, and all will be well...

According to the documentation in Xcdroaster, scsi emulation is still faster and more reliable than the IDE drivers - might just be that program.

Can anyone confirm/deny that SCSI emulation is still better for burning than the IDE interface?

Thanks for the reply.

The cdwriter works as a regular cdrom but I can't figure out a way to burn under 2.6.2...

odd... I did absolutely nothing special, and was able to burn just fine. I haven't tested for performance yet though.

What burning software are you using, and what errors is it generating?

Here's what I'm trying, and the readouts:

Code:

root@gobot:/usr/src/linux# cat /proc/cmdline 
BOOT_IMAGE=Slack-2.6.2 root=301 /dev/hdd=ide-cd
root@gobot:/usr/src/linux# cdrecord -scanbus
Cdrecord 2.00.3 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg 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@gobot:/usr/src/linux#

I included /proc/cmdline to show what I was passing to the kernel from lilo

EDIT to add what /proc/ide/hdd says about it...

Code:

UPDATE and BINGO!

:-D

Got it working, and am burning cd right now.

Here's the info:

Code:

mike@gobot:~$ cat /proc/cmdline 
BOOT_IMAGE=Slack-2.6.2 root=301 hdd=ide-cdrom

Then I searched around alittle more and came accross the command:

Code:

cdrecord dev=ATAPI -scanbus

Which listed my burner :-D Gave it an address of 0,1,0
So I tried how I usually do it when I had scsi emulation...

Code:

cdrecord -v dev=0,1,0 speed=8 whatever.iso

But it spat out the same old error, not able to open /dev/pg*

Quick glance at the cdrecord manpage led me to this permutation:

Code:

cdrecord -v dev=ATAPI:0,1,0 speed=8 whatever.iso

And I'm now in the cd-burning business :-D
Hope this helps some one else.
I was racking my brain over it.

you can also use a cmd like

cdrecord dev=/dev/hdd speed=8 whatever.iso

it works fine

robot5x · 02-26-2004, 06:10 AM

Thanks for this advice - I've been trying to figure this out too, but now it goes like a dream.

Bump to the top, since there seem to be a few more threads about this.

All of your hard work made my life better by removing this problem quickly.

I'm using kernel 2.6.2 and trying to burn a DVD. Following the suggestions here doesn't give you SCSI emulation and no one here is using the ide-cd driver in the 2.6.x kernel. If I run K3b using what has been posted I get an error message telling me that I'm burning in ATAPI mode.

How do I use the ide-cd driver in the 2.6.x kernel?

Note: I have the ide-cd module loaded.

nbitaud · 03-15-2004, 01:38 AM

I can burn CD without scsi emulation. I'm using the last version of k3b and cdrdao (1.1.8). Neverheless, as this last version of cdrdao doesn't exists when the las version of k3b has been released, you still have an error message

NB
