scsi emulation for dvd burner fails

[Guest Recon]

Hi,

i cannot burn with my dvd writer because it needs scsi emulation.

I already tried the obvious but that didn't do the trick. I also have

a working CD writer so all necessary scsi modules are present and

loaded. (Mandrake Linux 9.0, Kernel 2.4.18).

 

My drives:

hdb: LITE-ON DVDRW SOHW-1653S, ATAPI CD/DVD-ROM drive

hdc: SONY CD-RW CRX175A1, ATAPI CD/DVD-ROM drive

 

My lilo.conf (I already added the hdb=ide-scsi part):

append="devfs=mount hdb=ide-scsi hdc=ide-scsi quiet"

 

my fstab:

none /mnt/cdrom supermount

dev=/dev/hdb,fs=auto,ro,--,iocharset=iso8859-1,codepage=850,umask=0 0

0

none /mnt/cdrom2 supermount

dev=/dev/scd0,fs=auto,ro,--,iocharset=iso8859-1,codepage=850,umask=0

0 0

 

Devices in /dev:

/dev/scd0 -> scsi/host0/bus0/target2/lun0/cd

/dev/hdb -> ide/host0/bus0/target1/lun0/cd

/dev/hdc -> ide/host0/bus1/target0/lun0/generic

/dev/cdrom -> cdroms/cdrom0

/dev/cdrom0 -> cdroms/cdrom0

/dev/cdrom1 -> cdroms/cdrom1

/dev/cdroms/cdrom0 -> ../ide/host0/bus0/target1/lun0/cd

/dev/cdroms/cdrom1 -> ../scsi/host0/bus0/target2/lun0/cd

 

What I did so far:

1) add "hdb=ide-scsi" to lilo.conf

2) run lilo

3) make a new device scd1: mknod /dev/scd1 b 11 1

4) change hdb to scd1 in fstab

5) make symlink: ln -s /dev/scd1 cdrom

 

All this didn't work, my dvd writer was still not recognized by

 

cdreord:

cdrecord -scanbus:

Can somebody please tell me what I have to do to get scsi emulation

 

for my Lite-on dvd drive?

Many thanks.

I haven't done scsi emulation in a long time. You might just try a newer version of mandrake. The last several versions have not needed anything in the way of scsi emulation, because of a change int he way CD and DVD burners are handled.

 

Mandriva Limited Edition 2005 (the newest mandrake) is out and available now, and it's quite good.

 

If you really want to stick to 9.0, searchthe ahrdware forum for scsi. This was pretty welld iscussed back when scsi was still needed.

Add to that the fact cdrecord 1.11a32 is older that the great pyramid, and unlikely to work with any dvd+rw tools version, so DVD burning is right out of the question.

You're probably right, upgrading to a newer version is better than fiddling around with this "antique" 9.0. Thanks for your advice.
