Vista - Onboard and Radeon 7000

August 8, 2009 at 07:55:37
Specs: Windows Vista
Hi,

I currently have a system with onboard graphics and a radeon 7000.

I want to use the radeon 7000 with linux, which I have setup fine, I then boot into Vista and it also uses the Radeon 7000 even though it is disabed in the device manager.

Since I want to use both graphics cards in different OS's I cant select just one in the BIOS, I have to keep it as AUTO.

I was able to make linux ignore the onboard graphics so I would have thought it would have been easier to get vista to ignore the raeon 7000.

Does anyone have any solutions?

"....I then boot into Vista and it also uses the Radeon 7000 even though it is disabed in the device manager...."

There are no Vista drivers for the Radeon 7000 chipset. Vista is using default video drivers.

In most cases, if the Radeon 7000 card is AGP, the mboard's onboard video is automatically disabled when you install an AGP card in the AGP slot, and the settings regarding the amount of ram shared with the onboard video in the bios Setup are ignored by the bios.
You may be able to set Intialize Video First or Primary Video or similar in the bios Setup to Onboard video, AGP, or PCI, but if the onboard is disabled by installing the AGP card, the Onboard Video setting (or Auto, regarding the onboard video) has no effect.
If the Radeon 7000 is a PCI card, the onboard video may or may not be automatically disabled when you install the card - it's most likely to be disabled if the PCI video card is in the last PCI slot closest to the center of the mboard - next to the AGP slot it has one.

You have not said whether the onboard video works when you plug a monitor into it's port when the Radeon 7000 card is installed, or whether the onboard video shows up in Device Manager in Vista under Display Adapters (e.g. Computer - System Properties - Device Manager) as well as the disabled Radeon 7000 - if the onboard video doesn't show up there, it's been automatically disabled by the mboard's bios, and any settings to do with the onboard video are ignored in the bios Setup by the bios. .

"Since I want to use both graphics cards ..."

A pet peeve of mine...
The term CARD is frequently mis-used.
Both the Radeon 7000 and the Onboard video are a video or graphics chipset on a graphics or video or display adapter, but Onboard video, which is usually built into the main mboard chipset, is NOT A CARD. A video or graphics CARD, or any other CARD, is removable and installs in a mboard slot.

The solution for Vista? Use a card with a newer chipset that Vista DOES support. That depends on what the capabilities of your mboard are as well. An AGP Radeon 7000 card is 1X/2X/4X AGP capable - if the mboard can't support AGP 4X or 4X/8X, there is probably no 1X/2X AGP capable AGP card Vista has the drivers for, or that Vista drivers are available for. You can get PCI cards with newer chipsets that Vista has the drivers for, or that Vista drivers are available for, for not much money.

Are you physically moving the monitor cable from the R7000 to the onboard?? That's the only way it will work...

Thanks for your replies.

The Radeon 7000 PCI card is connected to my monitor with DVI, the onboard chipset is connected to my monitor with VGA. So I can easily which between both.


"If the Radeon 7000 is a PCI card, the onboard video may or may not be automatically disabled when you install the card - it's most likely to be disabled if the PCI video card is in the last PCI slot closest to the center of the mboard - next to the AGP slot it has one......"

As it is a PCI card, It is not disabled as when I installed Ubuntu it used the onboard chipset as default and I had to disable disable it, it then started using the Radeon 7000 card as default.


"You have not said whether the onboard video works when you plug a monitor into it's port when the Radeon 7000 card is installed, or whether the onboard video shows up in Device Manager in Vista under Display Adapters (e.g. Computer - System Properties - Device Manager) as well as the disabled Radeon 7000......"

No there is no output on the onboard when the Radeon is installed. Both show up in the device manager, Radeon is disabled.


"The solution for Vista? Use a card with a newer chipset that Vista DOES support. That depends on what the capabilities of your mboard are as well.

I need a PCI card as my motherboard does not have a AGP or PCI-E slot. I really dont want to buy a new card.

Linux will use both the radeon and the onboard depending on which I disable, so surely vista can do the same.

Any further suggestions?

Haven't tried it myself but I would guess Vista has the ability to set hardware profiles like WinXP. That should accomplish what you want, if available.

Hardware profiles are not available in Vista.

Is there not a registry value or configuration value somewhere that I can change which will just stop Vista using the Radeon card?

You may do better to post a new thread in the Vista forum. I have limited experience with Vista myself.

"Since I want to use both graphics cards in different OS's I cant select just one in the BIOS, I have to keep it as AUTO"

I am not sure the above statement is true. I believe that if you choose one as the primary graphics the other will still be available. You could try tweaking the system that way.

"The Radeon 7000 PCI card is connected to my monitor with DVI, the onboard chipset is connected to my monitor with VGA. So I can easily which between both."

If you have only one monitor and it can be connected to a VGA and a DVI connection (it has two cables, or two ports, one VGA, one DVI) , in all cases I know of, you can only use one or the other connection and get video from it at any one time (they can probably both be plugged in, but only one will work at any one time).

"As it is a PCI card, It is not disabled as when I installed Ubuntu it used the onboard chipset as default and I had to disable disable it, it then started using the Radeon 7000 card as default."

You may not need to disable the onboard video, if it is detected as well as the Radeon 7000, as long as it being enabled doesn't cause display problems - you can probably specify which is the primary display adapter in the operating system's configuration - e.g. In Win 95 to Vista, you can do that in Display Properties or similar.

Rarely, some operating systems will detect the onboard video when you install a card in a slot, some don't.
