Problem
Address and interrupt conflicts
EX2 Display Controller
Possible Solution
Ensure that the I/O and memory addresses reserved for the controller are not used by
other hardware devices.
The integrated onboard VGA controller uses the following addresses (hex):
I/O Addresses:
Standard VGA I/O: 3B0-3Df
Memory Addresses:
Video RAM: A000-BFFF
Video ROM: C000-C7FF
You cannot change the addresses of the EX2 controller. In case of an address conflict,
try to modify the I/O address of the add-on card that causes the conflict.
To support the special graphics processor on the controller, the system BIOS should
automatically assign a system interrupt to the AGP slot where the controller is installed.
There may be problems if your controller does not receive an interrupt or if a system interrupt
is used for more than one device.
Check the system configuration utility of your operating system for the interrupt assignments.
