Checking for address and interrupt conflicts
It is necessary to ensure that the I/O and memory addresses
reserved for the graphics board are not used by other hardware
devices.
The integrated on-board VGA controller of your Fire GL2 uses the
following addresses (hex):
I/O Address
Standard VGA I/O: 3B0-3DF
Memory Addresses:
Video RAM: A000-BFFF
Video ROM: C000-C7FF
Note: You cannot change the addresses of your Fire GL2. In
case of an address conflict, try to modify the I/O address of the
add-on card that causes the conflict.
Resolving Interrupt Conflicts
To support the special graphics processor on the Fire GL2 the system
BIOS should automatically assign a system interrupt to the AGP slot
where the card is installed. However, there may be problems if your
graphics card does not receive an interrupt or a system interrupt is
used for more than one device. In case of problems try the following:
Check the system configuration utility of your operating system
for the interrupt assignments.
Inspect your system BIOS setup for an option that says "Assign
IRQ to VGA" or something similar and ensure that this option is
enabled. If you do not have this option and your graphics card
does not receive an interrupt, contact your motherboard
manufacturer for an updated BIOS that has this option.
Some older ISA legacy add-in cards (with jumpers, non-PnP) may
cause a conflict if they are not configured in the ESCD (extended
system configuration data) area of the system BIOS. Please refer
to your computer's User's Guide for information on using the ISA
Configuration Utility ICU to add the required legacy card
resources to the system.
