MemMaker increases your conventional memory by loading device drivers and terminate-and-stay-resident (TSR) programs into upper memory. Sometimes a device driver or TSR program cannot be loaded into upper memory because of its design.

Since MemMaker is not aware of every device driver or TSR that cannot be loaded high, your system may stop responding (hang) when you run MemMaker. To recover from this situation, refer to the section titled "Your computer stops responding while MemMaker is loading a program or device driver other than EMM386" in Chapter 6 of the "User's Guide."


During the beta test of MS-DOS 6 Upgrade, Microsoft found several programs that could not be loaded high. These programs are listed in the MEMMAKER.INF file.

The following device drivers and TSRs cannot be loaded into upper memory and are not currently listed in the MEMMAKER.INF file:

   ATDOSHC.SYS             Quantum Hard Card EZ driver

  ADTSR.EXE                After Dark for DOS version 1.0


To avoid having to specifically exclude a device driver or TSR program each time you run MemMaker, add the filename to the MEMMAKER.INF file. For example, if GAI.SYS is causing your system to hang, edit the MEMMAKER.INF file with a text editor (such as MS-DOS Editor) to add the following line:

Device Drivers and TSR Programs Ignored by MemMaker

The following device drivers and TSR programs are listed in the MEMMAKER.INF file and therefore are not loaded high:
