Your computer has expansion slots for installing cards that give your system extra capabilities, such as a graphics card. Installing an ATI Radeon Crossfire 4870 X2 card gives your computer extra memory for processing video applications or games. After installing the Crossfire 4870 X2, your computer may not automatically detect the card. If your BIOS options aren't set to the correct settings, your operating system won't enable the card and you won't get any benefit from having the card installed.
Instructions
1. Click the Windows-logo button on the lower left-hand corner of the screen and choose "Shut Down." Tap the power button to restart the computer after the operating system completely shuts down.
2. Press the specific BIOS menu access key your computer uses, such as "F1," "F2," "Escape" or "F10." Check the bottom of the screen during the boot up process to see if your computer model lists the key you need to use with a prompt such as "Press F2 to enter the setup menu."
3. Press the right arrow button to scroll through the BIOS headings and navigate to the "Advanced" heading. Tap the down arrow key until you reach the "PCI Devices" option.
4. Hit "Enter" to open the "PCI Devices" menu. Select the option labeled "PCI Device Slot." If your computer uses more than one PCI expansion slot, highlight the specific slot that holds your Crossfire 4870 X2 graphics card.
5. Tap "Enter" again. Scroll to the "Enabled" option and press the "Enter" key to enable your Crossfire card. Press "Escape" and scroll to the "Exit" tab. Choose "Save and Exit" and press the "Enter" key. Wait for the operating system to boot up.
6. Bring up the "Start" menu and select the "Control Panel." Click "System and Maintenance" and navigate to the "Device Manager" option.
7. Click "Display Adapters" and locate the entry for your Crossfire card. Right-click the entry to bring up a new menu and select the "Update Driver" option. Choose "Search Automatically" and click "Next" and "Finish" to update the card's driver.
