MORE INFORMATION

If double buffering is required, it must be loaded from the CONFIG.SYS file as in the following example:

    DEVICE=C:\WINDOWS\SMARTDRV.EXE /DOUBLE_BUFFER

NOTE: This only loads the double buffer driver. It does not load the disk cache portion of SMARTDrive, and cannot be loaded high.

To force SMARTDrive to load into conventional memory, use the /L parameter in the AUTOEXEC.BAT file, as in the example below.

     SMARTDRV C: D: /L

When double buffering is enabled for SMARTDrive, system performance decreases. This is expected, due to the nature of adding an additional buffer to handle all disk reads and writes through conventional memory.

Loading SMARTDrive into low memory is quicker than loading it into an upper memory block (UMB) because this eliminates the additional step of buffering from the UMB to conventional memory.
