CD Burning on 2.4.26

benchcomptons · 05-29-2005, 11:10 AM

I am trying to get my computer to burn CDs. When I run cdrecord I get

bash-2.05b# cdrecord -scanbus
Cdrecord 2.00.3 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jï¿½rg 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'.

From this I figure that I need to enable ide-scsi emulation, so I edited lilo.conf, but now:

bash-2.05b# dmesg | grep scsi
Kernel command line: auto BOOT_IMAGE=Linux ro root=302 cdrom = ide-scsi
ide_setup: ide-scsi -- BAD OPTION
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
scsi0 : SCSI host adapter emulation for IDE ATAPI devices

so I don't think that it worked. I can't figure out the BAD OPTION. Also,

bash-2.05b# cat etc/fstab
/dev/hda1 swap swap defaults 0 0
/dev/hda2 / reiserfs defaults 1 1
/dev/hdb1 /home reiserfs defaults 1 2
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro,user 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,user 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

and,

bash-2.05b# lsmod | grep scsi
ide-scsi 9328 0

After some searching I think that I need to recompile my kernel with ide-scsi emulation into it.
But, I have never done a kernel recompile before so this makes me nervous...
Is this even the right way to go? My goal is to get cdrecord working.

By the way I am using Slackware 10

i'd think that the "bad option" is the reference to "cdrom" rather than the real ide device, i.e. hdb, hdc or hdd most likely. I'd also suggest removing the spaces either of the =, not sure if it actaully matters at all though.

ide-scsi isn't something normally left out of a 2.4 kernel, but if you do end up looking at recompiling a kernel, i'd VERY VERY strongly recommend you don't. instead build a 2.6 kernel, which doesn't need ide-scsi stuff anyway, and gives vastly improved burner performance as a result.

i'm not a slack user at all, but i'm sure slack does at least include a 2.6 kernel nowadays.

You might have the ide-scsi module loaded but do you have it specifying what devices should be using it at bootup from your lilo.conf file in the correct format?

Alright good, removing the spaces around "=" got rid of BAD OPTION. Now,

bash-2.05b$ dmesg | grep scsi
Kernel command line: auto BOOT_IMAGE=Linux ro root=302 cdrom=ide-scsi
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
scsi0 : SCSI host adapter emulation for IDE ATAPI devices

I still have the same problem with cd record.

Maybe getting the 2.6 kernel would be an instant fix to everything. How do I go about doing that?

Also, here is what my lilo.conf looks like:

image = /boot/vmlinuz
root = /dev/hda2
append = "cdrom=ide-scsi"
label = Linux
read-only

To update to the generic 2.6 kernel use these steps:

To compile your own try these steps:

Quote:

append = "cdrom=ide-scsi"

This line should go before your image section and why are you using cdrom.. should be your actual device name.. like hdc or something.

isbn't that what i said first time, drew??

Awesome! Upgrading to the 2.6 kernel did it.

no, hang on, that's still using scsi emulation isn't it??? you should *NOT* be using ide-scsi on a 2.6 kernel. instead it's direct to the IDE driver via ATAPI:

don't get this far and then go wrong!

Yeah, lots of stuff went wrong. It turns out that I did not even have the 2.6 kernel installed so I did that part wrong. But, in the process of doing it, something happened and I can burn CDs now. Since I only want to back up some stuff before switching out my hard drive, this is good enough.
