SYMPTOMS
When you use the ATI Rage II PCI video adapter as a secondary display adapter on a computer with multiple monitors, the secondary display adapter may not work properly. When you view the ATI Rage II PCI Properties dialog box in Device Manager, you may see the following message:

Multiple Display Support cannot start this device. The area of memory normally used by video is in use by another program or device. To enable Multiple Display Support, remove EMM386 or other memory managers from Config.sys and restart your computer.



RESOLUTION
To resolve this issue, use one of the following methods:

Method 1
Add an EMMExclude entry to the System.ini file. To do so, follow these steps:

 Using any text editor (such as Notepad), open the System.ini file. By default, the System.ini file is located in the Windows folder. Add the following line to the [386enh] section of the System.ini file:

emmexclude=c000-cfff

 Save and then close the System.ini file. Restart your computer.

Method 2
Add a line in the Config.sys file to load Emm386.exe. To do so, follow these steps:

 Using any text editor (such as Notepad), open the Config.sys file. The Config.sys file is located in the root folder.</li>  Add the following lines device= \himem.sys device= \emm386.exe x=c000-cfff

where is the path to the folder in which Windows is installed. </li> Save and then close the Config.sys file.</li> Restart your computer.</li></ol>

Method 3
Disable the line in the Config.sys file that loads Emm386.exe. To do so, follow these steps:

 Using any text editor (such as Notepad), open the Config.sys file. The Config.sys file is located in the root folder.</li>  Disable the following line by placing the word rem followed by a space at the beginning of the line device= \emm386.exe where is the path the folder in which Windows is installed. </li> Save and then close the Config.sys file.</li> Restart your computer.</li></ol>
