Yes that's what he means (hda is primary ide master, hdb is primary ide slave, hdc secondary ide master, hdd secondary ide slave).

Also, does it matter that the actual cd drive is a cd writr as well?

Not for reading CDs, you'll need to modify some stuff to get in burning under a 2.4 kernel. But first, get it to read Cds

This assumes your CDROM is your secondary master and your dvd is your secondary slave.

Ok, here goes...

Oops... I got

Code:

 # rm /dev/hdc /dev/hdd /dev/dvd /dev/cdrom
rm: cannot remove `/dev/hdd': No such file or directory
# /dev/MAKEDEV /dev/hdc
/dev/MAKEDEV: don't know how to make device "/dev/hdc"
# /dev/MAKEDEV /dev/hdd
/dev/MAKEDEV: don't know how to make device "/dev/hdd"
# ln -s /dev/hdc /dev/cdrom
# ln -s /dev/hdd /dev/dvd

when I ran the code... what went wrong?

Umm, my bad. Strip the /dev/ part before hdc and hdd on the makedev lines. It's safe to ignore any rm warnings/errors.

Code:

rm /dev/hdc /dev/hdd /dev/dvd /dev/cdrom
/dev/MAKEDEV hdc
/dev/MAKEDEV hdd
ln -s /dev/hdc /dev/cdrom
ln -s /dev/hdd /dev/dvd

ok, done that, I guess I need to reboot now...

will get back after the break

Matir · 07-13-2005, 03:50 PM

For the record... this is not windows.

You don't need to reboot after everything. (Though I imagine you've done or are doing that by now).

kriidler · 07-13-2005, 03:57 PM

I'm Back.
No luck;(
When I try to read the cd I get "mount: special device /dev/cdrom does not exist" and the dvd "mount: special device /dev/dvd does not exist".

Do the links you created still exist?

Code:

 ls -l /dev/dvd /dev/cdrom

Yep, how does one then refresh the system configuration?

Looks like

Code:

# ls -l /dev/dvd /dev/cdrom
lrwxrwxrwx  1 root root 8 2005-07-13 22:47 /dev/cdrom -> /dev/hdc
lrwxrwxrwx  1 root root 8 2005-07-13 22:47 /dev/dvd -> /dev/hdd

gbonvehi · 07-13-2005, 04:29 PM

And what about /dev/hdc and /dev/hdd?

both give me the same error: special device /dev/hdc (/dev/hdd) doesn't exsist"

Another thing I just noted: the link for the cdrom referes to hdc which is the dvd and the link for dvd refers to the cd, if I undestand the output from "ls -l /dev/dvd /dev/cdrom". Is this not the wrong way arround?

gbonvehi · 07-13-2005, 04:48 PM

I meant: ls -l /dev/hdc /dev/hdd
The /dev/cdrom and /dev/dvd symlinks look fine, so we need to see the place where they're pointing to, which are /dev/hdc and /dev/hdd

If /dev/hdc and /dev/hdd don't exist, use these commands:

Code:

cd /dev
./MAKEDEV hdc
./MAKEDEV hdd

I've just tested and MAKEDEV creates the devices on the current directory, so you should cd to /dev when issuing the command.

As you said, the symlinks are wrong so correct them again:

Code:

ln -sf /dev/hdc /dev/dvd
ln -sf /dev/hdd /dev/cdrom

kriidler · 07-13-2005, 05:14 PM

Ok, here's the result:

Code:

/dev# ls -l /dev/dvd /dev/cdrom
lrwxrwxrwx  1 root root 8 2005-07-14 00:03 /dev/cdrom -> /dev/hdd
lrwxrwxrwx  1 root root 8 2005-07-14 00:03 /dev/dvd -> /dev/hdc
/dev#

Ok, the CD is reading data CDs, I can't tell about music CDs because I've not yet got the sound sorted out

The dvd is still not reading anything...

If /dev/hdc and /dev/hdd don't exist, use these commands:

Code:

cd /dev ./MAKEDEV hdc ./MAKEDEV hdd

[/code]

and that one...?

Glad to hear that, so what does ls -l /dev/hdc says? That would be your DVD.

I promess if you install Slackware again it will be easier, just changing the symlink would have worked but I screwed up by swapping the arguments the first time I told you. I'm very sorry for that
