SCSI drives are not set to "Master" or "Slave." They are given an address of 0-7 (I believe some implementations allow 0-15). The lowest number has the highest priority and will become the boot device. Often this is the controller, which has been configured for how its attached drives are arranged (such as in a RAID).
The end devices on a SCSI cable must be terminated. This may be done with a dongle on a cable connector, or sometimes on the device itself with a resistor network (looks like a 14-pin DIP but is made up of resistors; not an IC).
Ok you are talking above my head here Im lost.Can the port configuration on the back of the drives that are on the moth board of the drive be configured to which order the drives boot in?I ask this because the 2 drives are set up with a diferent amount of port jumpers and the position is different on both of them.If you at the links where I first started a thread about these drives theres a pic that will show you what im trying to explain.The pic is of the second drive and uses 4 port jumper and the 1st drive only has 3 jumpers.Im not setup for raid yet but I don't want to that on this computer.I ust want to be able to boot to the 4 drives.
