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