Nvidia GeForce MX4000 video card won't start until Windows loads

Hi, new I'm here and have worked on my computers for many years with success. i have a problem with a new Nvidia MX4000 video card with an Asus P5P800-MX/CHANNEL-UAYGZ motherboard. All works well except there's no video signal until the Windows XP boots up and loads the driver. This means I can't see the Bios setup or dual boot screen on startup. It works fine with the built in video on the motherboard but I'd like to use the dedicated video card. Has anyone had this problem and suggestions to work around it.
Thanks, Don Black.

This usually happens with HDMI, are you using HDMI?
