I'm Trying to add SCSI Raid 5 capability to a PowerEdge 1800 with existing single 40GB SATA Drive.  The intent is to keep SATA as the boot and create data partition for SCSI Raid 5.

Unfortunately, I can’t get the system to acknowledge existence of any of the 3 SCSI drives.  Is my desired configuration valid?  Are there any specific jumpers that have to be modified from their factory settings?  I get no errors but BIOS doesn't see any SCSI hard drives.
