I have installed a second video card in a client PC. Windows tells me that the card is initialized. When I look in Device Manager I am being told the I need to unload EMM386.exe or other memory manager for Multiple Monitor support to enable. I have looked in sysedit and I dont see EMM386. Any suggestions.

emm386 is a TSR that goes hand and hand with himem.sys. it is in the autoexec.bat file. older ms-dos programs use these 2 files to manage upper memory. you can disable this by opening the autoexec.bat file it word and place a "rem" at the begining of the line. or Run msconfig got to the autoexec tab and uncheck the box next to emm386. hope this helps

What do you mean by "Unable to Change Adapters"
If you intend to use a different adapter then you should disable the unwanted adapter in device manager and restart the system .
If you intend to use both Adapters for multiple monitor support then first try disabling the other adapter , hook up the monitor to the new adapter and restart the computer to make sure the adapter is working fine . Then enable the old the adapter to use dual display feature .

Good Luck !!
