虚拟磁盘驱动程序 RAMDRIVER.SYS 蒋峻岭 1997-01-01   Uses part of your computers randomaccess memory(RAM)to simulate a hard disk drive. This device driver must be loaded by a <device> or <devicehigh> command in your CONFIG.SYS file.   RAMDRIVE.SYS利用计算机的随机存取存储器(RAM)模拟硬盘驱动器。该设备驱动程序必须在CONFIG.SYS文件中用device或devicehigh命令装入。   RAM drives are much faster than hard disk drives because your computer can read information faster from memory than from a hard disk.A RAM drive appears to be a normal hard disk drive;you can use it just as you use an hard disk drive.The most important difference between a real disk drive and a RAM drive is that because it exists only in memory,infor- mation on a RAM drive is lost when you turn off or restart your computer.   RAM drives(虚拟盘)比硬盘快得多,这是因为从内存读取信息要比从硬盘中读取快。一个RAM drive可视为普通硬盘驱动器,你可以象使用硬盘驱动器一样使 用它。两者之间最大的区别在于关机或重新启动时,因RAM drive仅存在于内存中,故在RAM drive中的信息将会丢失。   You can set up as many RAM drives as you want,up to the amount of memory your computer has. And you can do it not only using conventional memory but also extended/expanded memory(XMS/EMS),and the latter is strongly recommended if your system has them.   只要内存足够,你可以建立任意多个RAM drives。而且,除利用常规内存外,还可以利用扩展/扩充内存(XMS/EMS)来建立RAM drives,如果你的机器上有XMS或EMS,极力推荐使用它们。
