I'm trying to install a G400 into a Pentium II 266 with a Asus P2L97-S main board which has a very early AGP ports. The computer is running Windows 2000 Pro. After installing the latest drivers and setting the resolution, I get a message to say thatWindows Explore has performed a illegal operation and will be shut down. After this when I reboot I can?t get to the "Log On" screen as the computer keeps rebooting. The only way to get back in is to uninstall the Matrox sotfware from "Safe Mode".
Could someone please shed some light on this problem.

While I was unable to confirm my suspisions on Matrox's web site, I believe that you do not have the minimum hardware required to support the card.

The only details that I found stated that the G400 requires a2X or 4X AGP port.

I would first see if ASUS has a BIOS update for the motherboard.
Then, update the AGP mini-port driver for the motherboard. Get the latest version from the chipset mfg.

Install DirectX 8a or 8.1

Next, how much RAM do you have?
128MB would be the minimum I would attempt for this card. More is better.

In BIOS settings, make sure that APG is the primary display type.
Set AGP aperature to at least 64MB. But not more than 1/2 of system RAM.
Try both assign IRQ to VGA, and don't assign IRQ to VGA. Some combinations work better for a given system than others.

Finally, make sure that all remnants of the old video card driver are removed.

The early AGP port is not compatible with the the graphics card that you are trying to use,the card requires 2x or 4x
