Problem with Matrox Parhelia 128 in Asus P4P800-VM mainboard

Question for all,

My brother just bought a new system with an Asus P4P800 VM mainboard.
See
http://www.asus.com.tw/support/download/item.aspx?ModelName=P4P800-VM&...e=Lates
for details

He also got an Matrox Parhelia videocard. (
http://www.matrox.com/mga/products/parhelia/128mb.cfm )

Now, when i install the card, the system keeps booting from the on-board
Intel VGA card.
Should it not be that when the card is installed, the on-board card is
disabled ?
Also the card is not detected at all bij Windows XP home
I tried to change the VGA boot priority in the BIOS, but to no effect.

We're about to return the card to the store, but does anyone have a
suggestion what might be wrong (except of course that the card may be faulty
?)
Perhaps i'm doing something wrong.
The mainboard supports 0,8 and 1,5 volt cards, which i think the Parhelia
is.

Thanks.

Not on modern systems, no. A user might want to use BOTH the built-in
graphics as well as installed cards, which most modern operating systems
(Windows NT, 2000, XP, Linux) support.

Now that's a problem.

It should be set to external card before internal graphics.

It's AGP 2.0, which is basically AGP PRO without the extra power connector,
and requires 1.5V (do not put it in a 3.3V slot, or you'll likely fry
something).

Some things to check:

- Check whether there's a jumper on the motherboard (or BIOS setting) for
disabling the built-in graphics.
- Make sure the BIOS is not set to AGP 8x -- the Parhelia supports 4x and
2x.
- Borrow a second monitor, and hook both up -- one to each card. Boot into
Windows XP, and run the Hardware Wizard. If that's not doable, boot with
the Parhelia present, but the monitor hooked up to the internal graphics
card. Then go into the device manager, and disable the internal graphics
(under Display adapters). Shut down (don't reboot, as you will be asked),
move the monitor over, and start up.

Can you get into the BIOS screen with the Parhelia hooked up to the monitor?
