SYMPTOMS

EMM386.EXE version 4.45, which ships with MS-DOS 6.0, EMM386.EXE version 4.48, which ships with MS-DOS 6.2 and 6.21, and EMM386.EXE version 4.49, which ships with MS-DOS 6.22 may cause your system to stop responding (hang) with certain network cards installed.

CAUSE

This problem occurs when EMM386.EXE scans the adapter segment and detects a token-ring network card.
