Dell PowerEdge 440/800

O/S: Windows 2000 Server

I configure raid5 in the utilities. After this I went to install 2000 server and presses f6, pressed S to specify location for driver and get message "file txtsetup.oem could not be found"

Its a poweredge expandable raid controller 3/di v2.1-3 Build 2951. Does anyone have the PERC I need to install so that I can get this going.  Is there something I am missing. There is no drivers for this build which I suspect to be the issue. I could only find build 2947 and 2963. I was going to upgrade the firmware to the latest version then download the corresponding drivers is this the right thing to do.

Thanks in advance
