*** THIS GUIDE IS INCOMPLETE *** [[!toc levels=3]] # Scenario I am running 2.11-DEVELOPMENT DragonFly 64Bit with i5 Core on an IntelĀ® Server-Mainboard S1200BT with 8GB RAM. The Main System is on two Disks mirrored RAID1 with 500GB. I want to use dfBSD as our company Fileserver for important Backups. Also I found an old (not much used) Dawi controler (with Sillicon's SiL Chip) with 4 SATA Ports which I want to use for our Backup Fileserver. # Pre-steps ## Configuring the SATA Adapter Please make sure that the adapter is not configured (After the BIOS just before dfBSD starts) as RAID - just expose the disks individually to Dragonfly. We are going to setup a Software RAID. ## Identifying the disks After booting up the system please check that the Adapter you are going to use is correctly found: dmesg reveales: atapci1: port 0xe100-0xe10f,0xe110-0xe113,0xe120-0xe127,0xe130-0xe133,0xe140-0xe147 mem 0xfe4a1000-0xfe4a13ff irq 21 at device 0.0 on pci1
