标题Device Driver HIMEM.SYS

　　HIMEM is an extended-memory manager-a program that coordinates the use of your computer's extended memory，including the high memory area(HMA).so that no two applications or device drivers use the same mamory at the same time.
　　You install HIMEM by adding a<DEVICE> command for HIMEM.SYS to your CONFIG.SYS file.The HIMEM.SYS command line must come before any commands that start applications or device drivers that use extended momory;for example，the HIMEM.SYS command line must come before the EMM386.EXE command line.
　　设备驱动程序HIMEM.SYS
　　HIMEM是一个扩展内存管理程序，即协调计算机的扩展内存、包括高端内存区(HMA)使用的程序，因此两个应用程序或设备驱动程序在同一时间不能使用扩展内存的相同部分。
　　通过在你的CONFIG.SYS文件中增加一条HIMEM.SYS的DEVICE命令来安装HIMEM。 HIMEM.SYS命令行必须位于任何开始使用扩展内存的应用程序或设备驱动程序的命令之前；例如，HIMEM.SYS命令行必须位于EMM386.EXE命令行之前。
