SYMPTOMS
When you run Microsoft Windows version 3.0 under Microsoft MS-DOS version 5.0, 6.0, or 6.2, with Digital Equipment Corporation (DEC) Pathworks versions 4.x, your machine may stop responding (hang) when accessing floppy disks from the MS-DOS command prompt.

When you switch to the MS-DOS Prompt from within Windows 3.0, accessing drives A and B may cause the machine to hang.



CAUSE
This problem may occur if EMM386.EXE is loaded.



WORKAROUND
To see if the problem is related to EMM386.EXE, type &quot;REM&quot; (without the quotation marks) in front of the DEVICE=C:\DOS\EMM386.EXE line in your CONFIG.SYS file. Restart the machine. If the problem seems to go away, take the &quot;REM&quot; out and try the following:

 Make sure to follow the directions for installing Pathworks with MS-DOS 5.0 on page 25 of the version 5.0 &quot;Microsoft MS-DOS Getting Started&quot; manual. Exclude the area A000 - C7FF and specify no expanded memory by adding the following to your CONFIG.SYS file:

Device=EMM386.EXE x=A000-C7FF NOEMS

 Try excluding the system ROM. In the [386Enh] section of the Windows SYSTEM.INI file, exclude E000 - EFFF from the EMM386 if your EtherNet card is set for this area.
