When I try to write to my CD-writer with
'cdrecord -v speed=2 dev=5,0 cdimage.raw'
it fails to write because it thinks the
device is a CD-ROM. I've tried to boot with
the cd-writer turned off, then turning it
on after the boot completes but get the
same results. I'm using PPC Linux 4.1 which
is based upon Red Hat 5.0, with a Philips
CDD 2600 cd-writer. How can I write the
image to the CD-R?

Are you uasing the generic scsi device? for the first scsi it would be
/dev/sga

Sure it does, that works anyway.

You would read the CD-Writing HOWTO.

No, I'm not sure what you mean by this. How
would I use the generic scsi device?

With cdrecord, you don't: it doesn't want the '/dev' file anyway.

Does -scanbus show the drive correctly?

No. If I execute 'cdrecord -scanbus' I get this response;

Cdrecord release 1.6 jCopyright 1995-1998 Jorg Schilling
cdrecord: No target found

However I have 2 hard drives and the cd-writer on the scsi bus.

The old cdwrite used the sg device, the newer cdrecord uses the dev
paramater to sepcify the device without refering to the sg device.

Should return something like this: (An Intel system if that makes
any difference)

You need to recompile your kernel with SCSI generic support enabled.

He probably also has an ATAPI device, which means he should add SCSI
emulation and choose SCSI CDROM support. Also, he should pass the
parameter: "hdx=ide-scsi" where hdx is the device that the burner attaches
to as an ATAPI device. This will force the device to use SCSI emulation
instead.

Make sure you include 'generic' scsi support in the kernel. (The helps
on it mention something about scanners and other devices.) This is
needed since the kernel proper doesn't know a thing about cd burners and
it needs to allow the application (cdrecord) to issue scsi commands
directly to do its thing.

That -scanbus can't find anything is indicative of that: it uses the
generic scsi access to find drives on the system and query them.
