The card is not
performing
optimally?
• 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
FireGL card 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
FireGL card. 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 FireGL
card 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 check the system configuration utility of your
operating system for the interrupt assignments.
Your FIRE GL™ card requires an internal auxiliary DC
power source. If the card's internal power extension cable
is disconnected, a warning message will be displayed on
your screen and your system will not start.
Refer to Connecting power to the card
reconnect the internal power extension cable.
Check the Information tab of the Display Properties.
The Transfer Mode information must be AGP.
The Transfer Mode is not AGP? (for example, PCI)
• Install the latest chipset driver for the AGP chipset on
your motherboard.
• Contact your supplier or motherboard manufacturer
for further information.
