Glen, I tried again, and put the CD back in the CD drive after the reboot. This goes more smoothly, but I still get the color full screen message that there was a problem installing the selected software. (Again, I did not select any software to install.) The second reboot finally results in a prompt. (Which is further than I got before.) In general, there is big emphasis on applying updates to installed software. Does that not apply to directors running Sarge?
