Hello If the optional components to enable RAID functionality are installed then there should be an option in the system BIOS for Embedded RAID Controller. You can set the mode under that option to SCSI. That will set the controller to operate as SCSI controller without RAID functionality. The controller will use different drivers in the operating system and be detected differently by the operating system depending on which mode it is in. It will be presented as a PERC if RAID mode is enabled. If SCSI mode is enabled it will be presented as a SCSI controller. If you go the download page for the 6850 and change the OS to 2008R2 it will present what drivers are available for that OS. The SCSI RAID section has PERC  drivers for 2008R2, but I don't show a SCSI driver in the SCSI non-RAID section. 2008R2 should have a generic SCSI driver built into the driver CAB. Thanks
Hi Everyone, hope you might me able to help me, I have recently acquired a dell 6850 server, it has 1 x scsi 73 gb drive, how do I configure the bios so that it see's it as one normal non raid drive.... this isn't a production server just for testing... once I have the bios configured, I'm guessing the server 2008 r2 install disk still wont see the drive and i'll have to load a driver....... which one.... because I think I've tried all of them..... kinda at my wits end with it. Just FYi, I'm a experienced windows user and know my way around server OS but this is the first time i've played with server hardware... its been quite a steep learning curve :) many thanks, john
