Solved How can I force a Radeon 6450 to default to the VGA port?

Specs: Windows 7
Plug and Pray isn't working, and I think I need some kind of manual solution.

I have a HD 6450 that I am trying to install on a hp 462432-001 mother board. (It supports the shader models I need, and I don't need a lot of power. In before "Why would you do that?")

When the graphics card is in place, I can boot to Windows 7 (I can shut down by pressing Windows Key, Right Arrow, Enter), but the screen remains blank. Neither the VGA port on the card, nor the one on the mobo works.

Removing the card restores the mobo VGA port to normal function.

I suspect that the GFX card is not detecting the monitor, and defaults to one of the other two ports, but I don't have the cables, adapters or monitors to test that.

I can't install AMD Catalyst or Omega drivers while the card is out of the machine, because the installer depends on detecting the correct drivers automatically.

Is there any way to make this work without access to the Catalyst controls?

You may need to disable the on-board video in the BIOS.

Make sure the card is fully seated in it's slot - pop it in & out a few times to clean the contacts. Connect the monitor cable to the card & boot the system. Do you see the HP splash screen? If you do, press F10 to enter the BIOS setup menu. I'm not sure what settings will be available but look to disable the onboard graphics, change the shared memory, and/or change the initial display to the graphics card. Save the settings & reboot, then see if the display works in Windows.

Many older video cards didn't have UEFI compatible firmware and wouldn't allow the system to boot in UEFI BIOS mode. The HD 6450 is from around the time when PCs and motherboards started shipping with UEFI.

Look for a Legacy or Compatibility or CSM mode in your BIOS menu and try running the card in that mode.
