how to get a scsi cd drive working

**Game master pro** · 11-15-2005

I have a scsi cd drive which is connected to a scsi sound card. I know that both of these work, and when installing slackware i noticed that it says if you use a scsi device choose a kernel that supports it. So i chose scsi.i or something because it sounds like it supports scsi. Later on in the installation it says that you might need boot parameters for a scsi device, or something. So i didn't know what to do here, so i just pressed enter and continued, now that ive got it installed. I want to get it working, what type of things do i need to do now?

also the fonts are all dodgy in KDE, how can i change this?
and alsomore. How do i set up my internet, i wouldn't know what to do when it asks for my IP and stuf, and dns server i just don't know, can someone help me here?

i love linux

so many problems

you shouldn't be using slackware , then some of your problems would go away

the SCSI cdrom will probably be /dev/sr0, mine is

check your boot logs 'dmesg | less' to see

Hi

What kernel are you using ?

Code:

uname -r

will tell you.

Can you show us a copy of your fstab please.

What is your CD drive currently showing as, ie /dev/hdc, /dev/sda etc.

You could try putting a CD in and typing, as root:

Code:

mount -t iso9660 /dev/sr0 /mnt/cdrom

then

Code:

cd /mnt/cdrom

to see if you can see the contents of the disk.

Make sure that you have a folder called "cdrom" in the /mnt directory before you try this.

Then we will see if we can get you going. I suspect you need to either add a parameter to Lilo, or determine the correct naming convention for your device. Neither are too difficult, so stick with it.

I'm not on the computer at this moment, so i will tell you what i remember.

My kernel is scsi.i, thats what i selected when installing it

my fstab....I can't get that for you right now, i will try later.

I have a normal IDE cd drive as hdc, and when i try to mount my scsi drive it just says "/dev/sr0 is not a valid block device"

Then we will see if we can get you going. I suspect you need to either add a parameter to Lilo, or determine the correct naming convention for your device. Neither are too difficult, so stick with it.

What do you mean by this? What do i have to do with LILO?

Thanks for the help

Hi

I suspect that your kernel will be a 2.4.X.X variant (just named scsi.i) which is default for Slackware. The later 2.6.X.X kernels sort all this out for you.

I think you need to run scsi emulation so that the system recognises your ide CD as a valid block device.

Try adding this line to /etc/lilo.conf

Code:

append="hdc=ide-scsi"

(The quote marks are important)

Heres the top of mine as an example

Code:

$ cat /etc/lilo.conf
# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
append="hdc=ide-scsi"
boot = /dev/hda2
message = /boot/boot_message.txt

Then run

Code:

/sbin/lilo

and you should get a return similar to "added linux" with no obvious errors.

Then reboot. Once rebooted run

Code:

dmesg | less

to see if your cd device is recognised as a scsi device.

You should see an entry like this somewhere in the result

Code:

hdc&#58; attached ide-scsi driver.
scsi0 &#58; SCSI host adapter emulation for IDE ATAPI devices
  Vendor&#58; HL-DT-ST  Model&#58; CD-RW GCE-8320B   Rev&#58; 1.01
  Type&#58;   CD-ROM                             ANSI SCSI revision&#58; 02
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
sr0&#58; scsi3-mmc drive&#58; 40x/40x writer cd/rw xa/form2 cdda tray

Now when you run the mount command as in my previous post, you should get to see the files on the CD.

Let me know how you get on.

Ok i did that but this is what it says when i try to mount /dev/sr0

/dev/sr0 mounted on /mnt/cdrom
No median found

i think thats what it said, i did it 2 days ago so now ive forgotten, but i know it said no mediam found, but i put a cd in there, it didnt spin at all

Also ive got internet working on it all i had to do was type "dhcpcd eth0" thanks sdously

thats ide-scsi emulation for ide cdroms in 2.4 you do not need that

you need scsi support, probably via a module. but not ide-scsi
