SMARTDRV Command
Author: 山西 郭建军 Date: 1996-11-08
In SMARTDRV command you can specify a drive letter, either readcaching (reading information from disk cached) and write-caching(writting information into disk cached) are enabled or disabled. If you don't specify a drive letter, floppy disk drives, CD-ROM drives, and drives created using Interlnk are read-cached but not write-cached, hard disk drives are both read-cached and write-cached, and network drives are ignored.
创建磁盘缓存命令
SMARTDRV(DOS 6.2下)安装或配置磁盘缓存,即在扩展内存中创建磁盘缓存,磁盘缓存能有效地加速DOS的磁盘操作。当使用磁盘缓存时,在AUTOEXEC.BAT文件中或在命令提示符下,通过SMARRTDRV命令来加载。因为磁盘缓存建立在扩展内存中,所以在CONFIG.SYS文件中必须设置扩展内存管理程序。
在SMARTDRV命令中,可以指明对读缓存(从磁盘中读出的信息缓存)和写缓存(写入磁盘的信息缓存)允许或者禁止的驱动盘符。如果没有指明驱动器,则软盘、光盘驱动器及通过远程链接建立的磁盘驱动器,都是读缓存而不是写缓存,硬盘既是读缓存也是写缓存,而网络驱动器被忽略。
