I have checked the MD5SUM for disc1 is ok before I burn the CD from the iso image i downloaded from ftp mirror site. i have used different brands of cd and even lower the speed to 4x. I verify the cd by copy the entire disk in windows to a temp folder and the copy is no problem. I also install on 2 different pc and before installation, i go through the media test process and the result is pass. yet, the installation fails in the middle saying there is media error, or the package is corrupt ... what can i do ? __________________________________ Do you Yahoo!?
