himem.sys
An extended memory (XMS) driver included with DOS, Windows 3.1, Windows for Workgroups and Windows 95. Windows 95 automatically loads himem.sys during start-up. With older versions of Windows, and with DOS, himem.sys must be explicitly loaded by placing a command in CONFIG.SYS.WEBOPEDIA WEEKLY
