I already found out what was going on. The kabels of the scsi connection were not connected. :( But is solved. :) Now I going to try if I can load the system. Thanks everybody for thinking with me.
I've got a DELL poweredge 6400/900. When I use the "open manage server assistant 4.5_ISM_A00.ISO" the boot goes fine (option 1) but when I get in the assistant file it says no harddisks found. When I want to boot the cd to a harddisk (0ption 3 from the cd) it also says no harddisk found.   When using a windows 2000 advanced server disk it loads the bios, but when to wright to a disk it also says no harddisk found.   Why cant the system find one of the harddisks, I've got 8 scsi drivers in place (0 to 7), none of them drive's, but keep still.   Can somebody please help me with this problem.   Already thanks.   John
