SCSI ID doesn't have to be zero, it just has to be a unique number for each of the connected devices. The controller is set to ID 7 out of the box, so any other one is fine for the disk drive.
On the IBM drives, leave the "Force SE" jumper Off, set TermPower Enabled, choose an ID, and there you go.
Cabling: The end with the terminator on goes onto the far side, the other end plugs into the controller. The drive is connected anywhere inbetween, as you please. If you get a dual-channel controller there, make sure you put it onto the "LVD/SE" channel (the fast one).
First you visit SCSI BIOS (press Control-C), check that the SCSI channel(s) you got are included in the boot process (by default, they are). Then inspect each channel's properties, invoke the drive list to check whether your drive is seen, and best performance enabled (get into the controller's line, scroll all the way to the right, and hit "Restore Defaults" once). Save and exit.
On next reboot, enter system BIOS, and put your SCSI drive into the boot order. Modern system BIOSes list the drive by name, older ones just have a generic "SCSI" entry to choose.
That's it. You want to have a look whether the SCSI BIOS is the most current, 4.19.00 it should be.
