Section 2 | CHKSTATE.SYS | MEM


Starts the MemMaker program, which optimizes your computer's memory by moving device drivers and memory-resident programs to upper memory. To use MemMaker, your computer must have an 80386 or 80486 processor and extended memory. For more information about running MemMaker, see the chapter "Making More Memory Available" in the MS-DOS User's Guide. Do not use this command while Windows is running. Syntax MEMMAKER [/B] [/BATCH] [/SESSION] [/SWAP:drive] [/T] [/UNDO] [/W:n,m] Switches /B Displays MemMaker in black and white. Use this option if MemMaker isn't displayed correctly on a monochrome monitor. /BATCH Runs MemMaker in batch (unattended) mode. In batch mode, MemMaker takes the default action at all prompts. If an error occurs, MemMaker restores your previous CONFIG.SYS, AUTOEXEC.BAT and (if necessary) Windows SYSTEM.INI files. After MemMaker has completed, you can review status messages by viewing the contents of the MEMMAKER.STS file. (To view this file, use a text editor such as MS-DOS Editor, or use the TYPE command.) /SESSION Used exclusively by MemMaker during the optimization process. /SWAP:drive Specifies the letter of the drive that was originally your startup disk drive. Specify the current drive letter after the colon. This switch is necessary only if the drive letter of your startup disk drive has changed since your computer started. (The drive letter sometimes changes because of disk swapping performed by some disk-compression programs.) If the drive letter of your startup drive has changed and you do not specify this switch, MemMaker will be unable to find your system startup files. You do not need to use this switch if you are using Stacker 2.0, SuperStor, or Microsoft DoubleSpace. /T Disables the detection of IBM Token-Ring networks. Use this switch if your computer includes such a network and you are having problems running MemMaker. /UNDO Instructs MemMaker to undo its most recent changes. When MemMaker optimizes your system's memory, it makes changes to your CONFIG.SYS and AUTOEXEC.BAT files (and, if necessary, your Windows SYSTEM.INI file). If your system doesn't work properly after MemMaker completes, or if you are not satisfied with your new memory configuration, you can return to your previous configuration by starting MemMaker with the /UNDO switch. /W:size1,size2 Specifies how much upper-memory space to reserve for Windows translation buffers. Windows needs two areas of upper memory for its translation buffers. The size1 value specifies the size of the first region; size2 specifies the size of the second region. By default, MemMaker does not reserve upper memory for Windows; this is equivalent to specifying /W:0,0. Related Commands For information about loading device drivers into upper memory, see the <DEVICEHIGH> command. For information about loading programs into upper memory, see the <LOADHIGH (LH)> command.
