If you have a device= statement for SMARTDRV.EXE in your CONFIG.SYS
file, but you are not using the /DOUBLE_BUFFER switch, MemMaker may
change the device= statement to devicehigh=. If so, you receive the
following error message:
Double-buffering driver cannot be loaded into a UMB.
Do not use the devicehigh command or other load-high
utilities to load Smartdrv.exe
MemMaker recognizes and ignores the device= statement for SMARTDRV.EXE
only if you are using the /DOUBLE_BUFFER switch.
A device= statement in the CONFIG.SYS file does not load the
SMARTDrive cache; it loads only the double-buffering device driver
embedded in the SMARTDRV.EXE file. This device driver cannot be loaded
into upper memory.
To correct this problem, in the CONFIG.SYS file, change the
devicehigh= statement for SMARTDRV.EXE to device= and add the
/DOUBLE_BUFFER switch, then run MemMaker again.
