Also; if you intend to sell the unit with the Dell warranty, the unit will have to have the original Dell drives. If you're selling it without the drives, the person buying the unit will want to understand that they won't have access to the firmware downloads and such and may not get the unit working (with non-Dell drives).
Is it just firmware and OS type stuff?  I'm going to be selling a controller with the CF card and want to make sure I dont leave any private info on there.  I noticed a couple of non-built-in user accounts on there in the PASSWD file -- is it ok to just edit that file to remove them?  Thanks
PS4000 what's stored on the CF card?
