SYMPTOMS

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

CAUSE

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.

WORKAROUND

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.
