I have been working with an IBM PC Server 330 8640 PBO I just got. I used the procedure on the URL http://www.tek-tips.com/gfaqs.cfm/le...d/513/fid/3049 to move the CDROM from the RAID controller to the external SCSI controller and was able to install RedHat 7.2 from CDROM succsessfully. Good luck.
