Greetings.
This is not an urgent request for help since I will be upgrading to
kernel 2.6 sometime soon, but if some of you kind experts have a look at
my diagnostics it might be apparent what my problem is.


My setup is slackware 10.1 with kernel 2.4.31

I recently activated ide-scsi to use cdrecord. Now I can burn CDs but I
can't mount the CD for reading!

My drives are:
Two scsi hard discs on an Adaptec card.
One IDE CD/DVD writer using ide-scsi (Empirex 16x DVD writer)
One SATA drive plugged in but not configured yet.


My changes were the addition of these two lines to /etc/modules.conf:
options ide-cd ignore='hdb'
options scsi

and this line to /etc/lilo.conf:
append="hdb=ide-scsi"

Before that I was able to mount the CD using
mount -t iso9660 /dev/hdb /mnt/cdrom

I have tried a few variations like
mount -t iso9660 /dev/scd0 /mnt/cdrom
but without success.


This command works to burn a CD

Have you verified the ISO image by mounting using a loop device:

mount -o loop /mnt/sda2/temp/backup.iso /mnt/somedir

and inspecting /mnt/somedir? I remember using -dao for cdrecord of ISO
images but I don't recall if it is required.

Yes my iso mounts fine. I have tried mounting some known good CDs to no
avail.

However the OP did state that he was using the earlier kernel which does
need "hdb=ide-scsi".

Slackware 12, I understand, will have a 2.6(.21.5) kernel. Which if the OP
installs that should solve that problem. There is for specific Slackware
questions, alt.os.linux.slackware, and a UK, (although it has a world wide
membership), mailing list, here,

Hi.
I had tried it. Here it is again plus a few more guesses.
Can you glean anything from the dmesg query?
Regards.
