We have a Dell PowerEdge 850 server running SBS 2003. After installing an Iomega REV SATA backup drive connected to a PCI-E SATA controller, the server won't boot into Windows. The server is configured for RAID 1 with 2 240GB SATA hard drives. It almost seems like the server wants to boot from the Iomega device instead of the RAID hard drives. My temporary solution is to unplug the SATA cable from the controller, boot the system and then reconnect the cable once Windows loads.
