MS-DOS -> SMARTDRV.EXE

SMARTDRV.EXE is a disk-caching program that will almost always improve performance on a DOS-based system. A disk caching program's job is to intercept data that is being read from disk. The program will store this data in RAM, in a place referred to as the cache. The syntax for invoking the SMARTDRV.EXE program in either AUTOEXEC.BAT or CONFIG.SYS respectively is:

	[d:\path]SMARTDRV.EXE [switches]
	DEVICE=[d:\path]SMARTDRV.EXE [switches]

SMARTDRV.EXE Switches
Switch	Purpose
Device [+\|-]	Enables or disables read / write caching.
InitCacheSize WinCacheSize	Defines cache size.
/C	Forces data in the write cache to be written to disk.
/F	Empties cache before returning to command prompt.
/L	Forces SMARTDRV to load itself in memory below 640KB.
/N	Displays a command prompt wihtout forcing cached data to disk.
/Q	Tells SMARTDRV to forego the display of status messages when loading.
/R	Restarts SMARTDRV after clearing cache.
/S	Displays status information on SMARDRV's efficiency.
/U	Prevents CD-ROM caching portion of SMARTDRV from loading.
/V	Tells SMARTDRV to display status messages when loading.
/X	This default setting disables write-caching for all drives and is countered by the d:+ parameter.
/E:elementsize	Minimum number of bytes SMARTDRV will process at one time. The default is 8KB.
/B:buffersize	Number of bytes in read-ahead buffer. The default is 16KB.
