用MemMaker优化内存
如果有一台带80386或80486处理器和扩展内存的计算机,就可以通过运行MemMaker程序来释放常规内存。MemMaker修改CONFIG.SYS和AUTOEXEC.BAT文件,致使设备驱动程序和其他内存驻留程序占用较少的常规内存。MemMaker通过把某些设备驱动程序和内存驻留程序装入上位内存区来释放常规内存。
The upper memory area is the range of memory addresses that is normally set aside for use by hardware expansion cards. However,on most computers,hardware expansion cards do not use up the entire upper memory area. The unused areas of upper memory are call upper memory blocks(UMBs). You can use UMBs for running installable device drivers and other memory-resident programs. Moving these programs out of conventional memory makes more conventional memory available for other programs.
上位内存区(upper memory area)是一段内存地址范围,它一般保留给硬件扩充卡使用。然而在大多数计算机中,硬件扩充卡不占用整个上位内存区。未占用的上位内存区称为上位内存块(upper memory blocks,UMBs)。你可以使用UMBs来运行可安装的设备驱动程序和其他内存驻留程序,把这些程序从常规内存中移出,使更多的常规内存可供其他程序使用。
