cd-rom devices will not work

Description of Problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
I must have hit a dead time. Had all detail on the web page waiting for a
password....and when I finally got it it was all gone.
Intalled 7.2 workstation and the cdrom devices don't work. I have done a lot of
tests and got advice from the Grub developers and I can't get them to work. In
7.1 I'm using now the read-only and read/burn cdroms both work fine.
The only thing remaining is to unplug the read/write cdrom and re-load 7.2 and
then try to install the read/write.
When I use cdrecord -scandisk it correctly finds both cdrom devices. I assume it
will work. But the normal use of both cdroms is not there.
Karl Larsen again. I deleted 7.2 from the /dev/hda3 partition and then re-loaded
it with only one cdrom connected. It loaded normally without any problems but
when it came up I tried a cdrom in the driver and nothing happened. Then I tried
mount /mnt/cdrom and it came back "no such block device". I then displayed with
ls -al /dev/cdrom and found it's linked to /dev/hdc as it should be.
It is my opinion now that there is either something wrong with the loader
program or there is a major bug in either the kernel or some other part off the
I got the new install of 7.2 working. I found that modules cdrom and ide-cd were
not being loaded on this version. I loaded them with modprobe and that got both
cdrom devices working. But not as well as under 7.1.
I need to know what rc file loads these modules and I can explore more.
Bugzilla is for reporting bugs. I dont see the problem you are having
as a bug, but rather as a technical support / configuration issue.
Please use our mailing lists for support questions like this.
To get both the cd-rom reader and the cd-rom burner to work. I had to add
modprobe lines to rc.local. I can send you rc.local but not in this window. The
burner needs to appear as a scsi drive and I load that kernel driver with Grub.
Back when it was just loaded neither cd-rom worked but the ide-scsi kernel
driver was loaded. For sure it's a problem with the initial load and is "hard"
to fix if your not a skilled linux user.
