MEMMAKER


Description | Syntax | Parameters | Switches | Related | Notes | Examples | Errorlevels | Availability

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 DOS User's Guide.

CAUTION: Do not use this command while Windows is running.


Syntax

MEMMAKER [/B] [/BATCH] [/BATCH2] [/SESSION] [/SWAP:drive] [/T] [/UNDO] [/W:n,m]


Parameters

none.


Switches
/B (v6.0 Win95 ONLY)
Displays MemMaker in black and white. Use this option if MemMaker isn't displayed correctly on a monochrome monitor.
/BATCH (v6.0 Win95 ONLY)
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 DOS Editor, or use the TYPE command.)
/BATCH2 (v7.00 Win95 ONLY)
Runs MemMaker in batch (unattended) mode and exits. 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 DOS Editor, or use the TYPE command.)
/SESSION (v6.0 Win95 ONLY)
Used exclusively by MemMaker during the optimization process.
/SWAP:drive (v6.0 Win95 ONLY)
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 (v6.0 Win95 ONLY)
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 (v6.0 Win95 ONLY)
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:n,m (v6.0 Win95 ONLY)
Specifies how much upper-memory space to reserve for Windows translation buffers. Windows needs two areas of upper memory for its translation buffers. The n value specifies the size of the first region; m 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.

Notes
Examples

To run MemMaker in batch mode and to direct it not to reserve any upper memory for Windows translation buffers, use:

    MEMMAKER /BATCH /W:0,0

To have MemMaker restore your previous system configuration, use:

    MEMMAKER /UNDO

Suppose you use a disk-compression program. Your startup disk is drive C, but after the compression driver starts, drive C becomes your main compressed drive. Your startup files are now on drive D. Because of this drive-letter swapping, you would start MemMaker by using:

    MEMMAKER /SWAP:D

This command specifies that the current drive D was originally the startup drive and contains your CONFIG.SYS and AUTOEXEC.BAT files.

Note: You do not need to use the /SWAP switch if you are using Microsoft DoubleSpace disk compression or the Stacker 2.0 disk-compression program.


Errorlevels

none.
