This article was previously published under Q108818





SYMPTOMS
If you have the setting NoEMMDriver=On in the [386Enh] section of your SYSTEM.INI file, your system may stop responding (hang) at startup with the Windows Logo screen displayed after you enable 32-bit file access.



WORKAROUND
If you delete the NoEMMDriver=ON entry, your system may be able to start Windows.

NOTE: This works only if your system configuration requires the RMM.D32 file for 32-bit file access. The RMM.D32 file is required for 32-bit file access with MS-DOS 6.2 DoubleSpace, Stacker, and hard disk drive controllers that are not INT 13 compatible.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows for Workgroups version 3.11. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



MORE INFORMATION
When the entry NoEMMDriver= is set to ON, it prevents Windows 386 enhanced mode from installing the expanded memory driver. This differs from setting EMMSize=0, which prevents upper memory blocks (UMBs) from being allocated but does not prevent the EMM driver from being loaded.

The default value for NoEMMDriver= is OFF.

A number of third-party software applications recommend placing this line in the SYSTEM.INI file to optimize Windows. If you experience any problems with your applications after you remove this entry, contact the manufacturer of the application. KBCategory: kbenv kbbuglist kbfasttip kbtshoot
