Question: I'm using an AGP 8X card to replace the old AGP 4X card on P4VX4. In the BIOS, I can see AGP mode icon when the AGP 4X card is installed. But there is no AGP mode option when AGP 8X card is installed. Why?(9/15/2003) Answer: When an AGP 8X card is detected, the system will run at AGP 8X automatically. At this moment, the AGP mode option is not provided.
