I have a 5500 already running Core 2 - finally nixing a Windows Server on an identical machine. So figured I'd test Core 4 by wiping the Windows server and doing a clean install - all the latest ROM patches etc.. on the IBM RAID SERVER. Everything goes fine - automatically partition, select the server config I want (fairly slim config, command line server, plus PostgrSQL) until the Install goes to start the install, it formats the partitions and starts to copy the set up to the drives. After awhile it complains it cannot continue to copy and suggests we have run our of disk space. I think it may be trying to copy the install to the boot partition. I've gone though it a couple fo times - the mounts look right, I increased the boot space to 128MB on the off chance it was complaining about the boot partition - no change. The drives are two logical drives on a RAID 1 configuration (4 physical disks in all). I've been through it a number of times today. Help appreciated. Steven
