1.  Q. How can I free conventional memory on my computer?
    
    A. You can optimize your computer memory use automatically by
       running the MS-DOS 6.0 MemMaker program. There are some
       restrictions on using MemMaker to optimize your system memory.
       MemMaker works on 80386 and 80486 computer systems only; it
       does not work on 80286 or 8088 systems. It works with the MS-
       DOS HIMEM.SYS and EMM386.EXE memory-management utilities only;
       it does not work with third-party utilities, such as Qemm(TM)
       and 386MAX(R).
    
       MemMaker reviews your CONFIG.SYS and AUTOEXEC.BAT files and
       then optimizes them by loading terminate-and-stay-resident
       (TSR) programs and installable device drivers into the memory
       area between 640 kilobytes (K) and 1 megabyte (MB), which is
       called the upper memory area (UMA). Before you run MemMaker,
       verify that all device drivers are being loaded properly and
       that any hardware they control is also functioning correctly.
       To run MemMaker, type "memmaker" (without the quotation marks)
       at the MS-DOS command prompt, and press ENTER.
       
       Read each screen and follow the instructions listed. During
       this process you are prompted to choose either Express Setup or
       Custom Setup. We recommend using the express mode of MemMaker
       Setup initially. Setup prompts you to verify that your
       applications require expanded memory. If you are unsure, refer
       to your software documentation.
       
       MemMaker reboots your machine twice while it determines the
       optimal configuration. When it has chosen a configuration, a
       screen reports how much memory was available before you ran
       MemMaker and how much is available now. If the displayed memory
       is not what you expect or need, press the ESC key to undo
       changes made by MemMaker.
       
       If you accepted the changes made by MemMaker and now want to
       undo them, type "memmaker /undo" (without the quotation marks)
       at the MS-DOS command prompt, and then press ENTER.
       
       For more information about MemMaker, please refer to the
       "Managing Your System" chapter of the "Microsoft MS-DOS 6
       User's Guide."

2.  Q. After MemMaker rebooted my computer, the computer stopped
       responding ("hung"). How can I correct this problem?
    
    A. MemMaker tries to use UMA locations that it determines are
       free. If your machine hangs, note any error messages that are
       displayed, then restart your computer. MemMaker detects that
       your computer is being restarted before the optimization is
       complete and displays a screen listing possible reasons for the
       interruption and instructions for resuming or quitting the
       optimization. Accept the default options to continue.

       For more information regarding MemMaker, please refer to the
       "Making More Memory Available" chapter of the "Microsoft MS-DOS
       6 User's Guide."

3.  Q. After running MemMaker, some programs on my computer no longer
       function properly. How can I correct this problem?
    
    A. Some programs and device drivers are not designed to be loaded
       into the UMA. If you have such a program, it cannot work
       correctly when loaded into the UMA. To correct this problem,
       you must change how the program is loaded, thus changing where
       it will be loaded in memory. Two procedures for doing this
       follow.
    
       If the program is being loaded from the CONFIG.SYS file with a
       DEVICEHIGH command, open the CONFIG.SYS file in an ASCII text
       editor, such as MS-DOS Editor, and change the line for the
       device driver to read device instead of devicehigh. Save the
       file, quit the text editor, and then reboot your computer by
       pressing CTRL+ALT+DEL.
       
       If the program is being loaded in the AUTOEXEC.BAT file, open
       the AUTOEXEC.BAT file in an ASCII text editor and remove the
       LOADHIGH (LH) command for that program. Save the file, quit the
       text editor, and then reboot your computer by pressing
       CTRL+ALT+DEL.
       
       For more information on the LOADHIGH and DEVICEHIGH commands,
       refer to the "Microsoft MS-DOS 6 User's Guide" or type "help
       loadhigh" or "help devicehigh" (without the quotation marks) at
       the MS-DOS command prompt. Also, check the documentation that
       comes with your application for details on memory location and
       usage.
       
4.  Q. I am using the Multi-config commands and I want to optimize my
       system. Are there any special precautions I should take?

    A. MemMaker views the CONFIG.SYS and AUTOEXEC.BAT files as a
       single unit. When you run MemMaker, it removes all references
       to memory managers and the FILES, BUFFERS, and DOS commands. It
       then adds the following commands to the top of the CONFIG.SYS
       file:

          device=c:\dos\himem.sys
          device=c:\dos\emm386.exe settings
          buffers=setting
          files=setting
          dos=umb
          lastdrive=setting
          fcbs=setting

        Note: The setting values for BUFFERS, FILES, lastdrive, and
        EMM386.EXE are determined by MemMaker based on your
        configuration.

       Because of this design, MemMaker cannot optimize CONFIG.SYS and
       AUTOEXEC.BAT files that use Multi-config commands.
       
       To optimize multiple configurations using MemMaker, you must
       have separate configuration files for each item on your
       multiple configuration menu, and run MemMaker on each set of
       files. This is a complex process. Refer to the "Making More
       Memory Available" chapter of the "Microsoft MS-DOS 6 User's
       Guide" to clarify how to use MemMaker with multiple
       configurations.
       
       For more information on the multiple configuration commands,
       refer to the "Configuring Your System" chapter of the
       "Microsoft MS-DOS 6 User's Guide."

       For more information on MemMaker, refer to the "Making More
       Memory Available" chapter of the "Microsoft MS-DOS 6 User's
       Guide."

5.  Q. After optimizing my system with MemMaker, I receive the error
       message "Bad command or filename." How can I correct this
       problem?
    
    A. This error message indicates that MS-DOS cannot find a file or
       program. Check the drive, path, and filenames to verify that
       the filenames and locations are accurate. This error may occur
       if MemMaker changes programs loaded by a third-party memory
       manager. MemMaker does not support the use of third-party
       memory managers, and all such references in the AUTOEXEC.BAT
       and CONFIG.SYS files should be replaced with the corresponding
       MS-DOS memory manager or command.

       For more information on MemMaker, refer to the "Making More
       Memory Available" chapter of the "Microsoft MS-DOS 6 User's
       Guide."
