cdrecord for PPC440EP, Lunux 2.6.13

[Leonid]

Hi:

I'm trying to use cdrecord under Linux 2.6 on PPC440EP board. It informs
that there are certain problems with Linux 2.6, but in general it works.
For example, I can burn image on USB CDROM.

However I couldn't make it working with my IDE CDROM (I have Sony
CRX320AE). I think I have enabled anything SCSI related in kernel, yet
cdrecord cannot recognize it. I realize that I must forward to kernel
hdb=ide-... parameter. I used 2 different parameters for bootarg:

1) "hdb=ide-scsi":

ide-scsi is deprecated for cd burning! Use ide-cd and give dev=/dev/hdX

However cdrecord doesn't like him:

2) Since ide-scsi may be deprecated, I tried "hdb=ide-cd":

cdrecord doesn't like this driver anyway:

Could it be that this CDROM needs some special drivers? Should I simply
get another CDROM?

Thanks,
