</div>When I do that, I get nothing. But, this is promising (BTW, my prev<br>
ide-cd thingy was left over from another CentOS box. It's not effective<br>
on this one.).<br>

I popped a CentOS DVD in, got one image on the desktop and one mount<br>
listed from the mount command and one nautilus box popped up..<br>
<br>
I removed that and inserted a Mark Knopfler DVD and totem automatically<br>
popped up to do it's usual bitch about plugins.<br>
<br>
Mount showed one on /media/SHANGRILA and desktop had one ICON for it.</blockquote><div><br>So what does grep ^hda /var/log/dmesg tell you about your optical drive Bill? <br></div><div> </div>Being a Unix user of 25 years, I'm always a little suspicious of these new-fangled things like desktops. ;-)<br>
However, if you're using Gnome then please have a look at System --> Preferences --> Removable Drives and Media<br>I know that there is a difference in the automount of a data CD/DVD when the user is root (basically it doesn't, you would have to right-click on the icon and select mount manually) and when the user is a normal user (automount err automounts).<br>
</div><br>Lanny or Bill - Sorry I'm loosing track. One of you has three boxes; in boxes #1 & #2 the drives behaves as you want, in box #3 the drive misbehaves. Have you tried the test of swapping the drives in - say - boxes #2 & #3 and seeing if the problem moves with the optical drive or stays with box, #3?<br>
<br>The hd{a|b|c|d}=ide-cd kludge certainly isn't required with the CentOS 5 2.6.18-series kernels. I last came across it with a 2.4.8-* IIRC.<br><br>Just a few more of my thoughts, for now.<br><br>Alan.<br><br><br>
