I would say Yes, the CD-ROM can not share the same address. Also have you configured the addresses on the drives, so that the first drive on the chain is '6' then the next is '5', then '4', all the way to '0' on the first buss? The system accesses the first ID nearest to '7' first '6', then goes to 5,4, 3, and so on to '0'. Zero being the last drive on the chain, if you use them all, it would be terminated, all others no terminators or 'power on termination' as with a CD-ROM. Some will say NO NO NO put the internal boot drive on address '0', but with a SCSI chain the "main" boot drive should be the one nearest the system, and that is '6', because as we all know the system is '7', and it does not jump to '0' first, it looks for the nearest SCSI address then goes on from there.
