I just recently received the Precision T5600 Workstation. The original configuration was setup in RAID 1 with 2 SATA drives. I killed the RAID and loaded a single SAS drive in the RAIDs place. When I loaded a Windows 7 installation disk, windows could not see any hard drives. So my question is there a place where I can download the SAS/SATA controller's driver and throw it on a thumb drive to load during the Windows 7 installation process?

Thanks.
