MP5 checks

Does anyone know if the YaST installer does an MP5 check on each package as it is installed. I ask because I have a flaky DVD-ROM drive but it appears to have installed all the packages but I'm concerned that there may be some hidden errors in the installation. Anybody have any info? -- Donald D. Henson, Managing Director West El Paso Information Network The "Non-Initiation of Force Principle" Rules
