Hello: The box is dual boot (Win XP & CentOS 5). A Dell Dimension 4300 Celeron. There was an intermittent problem with this last year and last Thanksgiving, I wiped the HD and installed Win XP and CentOS 5 clean. My daughter asked me to install KStars which is in the kdeedu RPM on the Fedora Core 6 Install DVD. I did that, without any problems, on my box and on my wife's box. On the Dimension 4300, in Linux, the OS thinks the DVD ROM is empty. I suspect this is a HW problem, but: (a) Windows can see everything on the DVD, without any problem and (b) I can boot the Fedora Core 6 Install DVD, without any problem. If anyone on the ML has ideas about what might be wrong with the installation of the OS (I have GNOME and KDE installed and the problem is the same with either desktop) please give me your suggestions about how to get the DVD to mount properly. TIA! _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
