MS-DOS MemMaker may stop responding (hang) on a system that includes the line DEVICE=C:\DOS\EMM386.EXE AUTO in the CONFIG.SYS file. When you run MemMaker with this line active, it hangs on a blue screen that says "Microsoft MemMaker." At this point, you must turn off your computer and then turn it on again. Pressing CTRL+ALT+DEL does not work.


The EMM386.EXE AUTO switch enables expanded memory support only if a program calls for it. Therefore, EMM386.EXE is essentially on hold if you are using the AUTO switch. MemMaker tries to determine the status of EMM386.EXE, but it cannot do so when the AUTO switch is active.
