It's more of a hardware problem

"In order to cut costs, newer motherboards feature a lot of integrated devices. (LAN, sound, RAID, etc.) The ROM for these devices is placed in the upper memory area (UMA), where the EMS pageframe typically resides. When EMM386 or the NTVDM EMM installs, it looks for a contiguous 64K block of memory in the UMA for a pageframe. If there is no room in the UMA for a pageframe, the EMM will not install and you have no EMS."
Most people think EMS never works with XP because it's disabled by default. If your motherboard supports EMS, 99% of the time XP's EMM will work fine if you enable it. Back to Programming Talk
