passing the argument "hda=ide-scsi" (no quotes) in Xboot works. The following
was found in dmesg:

scsi1 : SCSI host adapter emulation for IDE ATAPI devices <----- my internal
cd-rom
  Vendor: MATSHITA Model: CD-ROM CR-585 Rev: ZS20
  Type: CD-ROM ANSI SCSI revision: 02
scsi2 : MESH
mesh: target 2 synchronous at 5.0 MB/s <----- my external cd burner
  Vendor: YAMAHA Model: CRW8424S Rev: 1.0j
  Type: CD-ROM ANSI SCSI revision: 02

... and further down I find ....

Attached scsi CD-ROM sr0 at scsi1, channel 0, id 0, lun 0
Attached scsi CD-ROM sr1 at scsi2, channel 0, id 2, lun 0
sr0: scsi3-mmc drive: 24x/24x cd/rw xa/form2 cdda tray
Uniform CD-ROM driver Revision: 3.12
sr1: scsi3-mmc drive: 24x/16x writer cd/rw xa/form2 cdda tray
Linux Kernel Card Services 3.1.22

So, I made the /dev/sr0 and /dev/sr1 devices:

mknod /dev/sr0 b 11 0
chgrp disk /dev/sr0

mknod /dev/sr1 b 11 0
chgrp disk /dev/sr1

then I created two symbolic liinks:

[root@dhcp-159-66 marbre]# ln -sf /dev/sr0 /dev/cdrom
[root@dhcp-159-66 marbre]# ln -sf /dev/sr1 /dev/cdrw

and in /etc/fstab:

/dev/cdrom /mnt/cdrom auto noauto,ro,user 0 0
/dev/cdrw /mnt/cdrw auto noauto,rw,user 0 0

IT DOESN"T WORK! I can't play audio cd's or mount data cd's, nothing. What am
I missing here?
