I just download CENTOS 5.4 DVD ISO X86_64 version from internet. I tried to install it on DELL server and get following error message before RPM start install: parted_1.8.1-23.els.x86_64.rpm can NOT open anyone know why? Should I download it again from any good site? If I install CENTOS 5.3 and use yum update, will it go to CENTOS 5.4? Thanks. ___________________________________________________ 您的生活即時通 － 溝通、娛樂、生活、工作一次搞定！ http://messenger.yahoo.com.tw/
