winternals erd 2005

I am trying to reset the password on a Compay Proliant ML150 server which has SATA raid harddrives. I have created the driver from the Compaq CD. When I do the F6 thing to load the driver, (I cannot see the drives when I log on with erd 2005)I get an error and am unable to load the driver and obiously cannot see the windows installation.
