I checked any my bios does not have this setting.. and it is in legacy mode.. do I need to update bios?
You can check with the Mobo maker for updates to it (if any). But normally a Mobo with built in video has a option "Use onboard video first" or some such statements. If there is NO options at all for that you would have to go to the Mobo maker and look up in their forums, FAQ and / or READ THE MANUAL (pdf) for that option.
You 'added' this to a "dell", how OLD is this Dell computer?
