SMARTDrive, the MS-DOS disk caching driver, supports the use of extended
memory and expanded memory, but not conventional memory. SMARTDRV.SYS was
designed as a disk caching program for environments with memory that MS-DOS
does not use heavily: extended and expanded memory. The maximum 640K of
conventional memory is so valuable that most people don't waste it with
disk caching.
Most people would rather use this precious conventional memory for running
programs, and not for SMARTDrive to speed up their systems. However, if you
do want to use SMARTDrive to speed up your system, there are two upgrade
paths available, which are as follows:
- Obtain an expanded memory board (or software to emulate an expanded
memory board, such as the MS-DOS version 4.0 driver EMM386.SYS).
-or-
- Obtain an extended memory board.
SMARTDrive can be used in the extended or expanded memory areas. MS-DOS
original equipment manufacturers (OEMs) may choose to modify SMARTDrive to
support conventional memory if they decide that the memory choices
SMARTDrive was designed with are not adequate.
