#E.1.2.7 Notes:
#Specifying the Initial Memory Cache:
#specify for the InitCacheSize parameter to the nearest multiple of 16.
#you plan to run an application that uses expanded or extended memory,
#specify a cache size that leaves enough memory for that application after
#SMARTDRV.SYS is installed.
#If there is not enough memory to create a cache of the size you specify,
#SMARTDRV.SYS creates a smaller cache, using the available memory.
#Using Extended Memory:
#first install HIMEM.SYS or other extended-memory manager that conforms to
#the Lotus/Intel/Microsoft/AST (**) Extended Memory Specification (XMS).
#In the CONFIG.SYS file, the DEVICE command that installs the
#extended-memory manager must precede the DEVICE command that installs
#SMARTDRV.SYS.
#Using Expanded Memory:
#configure your system to provide expanded memory.
#the DEVICE command that installs the expanded-memory manager must precede
#the DEVICE command that installs SMARTDRV.SYS.
#manager must conform to the Lotus/Intel/Microsoft Expanded Memory
#Specification (LIM EMS).
#Manager" in topic C.0.
#Using SMARTDRV.SYS: If you place the disk cache in extended memory, you
#will probably have the best results.
#You Cannot Run the Disk Compaction Program:
#run any disk-compaction program while SMARTDRV.SYS is loaded.
