Here's the error message I get when installing packages from the second CD: Error The file /mnt/source/RedHat/RPMS/usbview-1. 0.2.i386.rpm cannot be opened. THis is due to a missing file, a bad package, or bad media. Press <return> to try again. OK Note it gets stuck in a loop becaue the only choice is to try again.
