Hello everyone: Just to bring you up to speed, I'm running SuSE 9.3 professional in 64-bit mode on an AMD 64 laptop. Recently I was experiencing problems with YaST (Yet another System Tool) as I couldn't install additional software packages. YaST couldn't 'see' the DVD and would report: ERROR (InstSrc: E_no_instsrc_on_media) [ /media.1/media ] This file ( /media.1/media ) contains text identifying the make and model of the software (SuSE 9.3, DVD 1). Somehow this file was corrupted on the laptop and this was preventing YaST from 'seeing' the DVD. However, after a clean install, everything worked. So, I assumed that the problem was with the YaST update packages and, on the next update, I avoided all of the YaST patches only to have the problem re-surface on the next reboot. After reading my posts, another user suggested I attempt another upgrade but not to upgrade the Linux kernel. This seems to have solved the problem. I did a fresh install - everything worked. I even used YaST's 'Check Media' program on the DVD - it got a clean bill of health. I then did an upgrade but I DID NOT upgrade the LINUX KERNEL. Well, after the upgrade and a re-boot - everything is working correctly. And YaST's Media Check gave the DVD another clean bill of health. So, there must be some sort of incompatibility problem between my machine and the kernel upgrade. Hope this helps. In closing, I would like to thank all of you who helped to solve this problem. It was a dilly. Cheers, Mike
