The information in this article applies to:

Microsoft Windows operating system versions 3.0 and 3.1

SUMMARY

The Microsoft Windows operating system version 3.1 may hang during startup on Emerson 286 and 386sx computers with Quadtel HT113 286 or 386sx BIOS version 3.05.08, ROM version 1.04, dated prior to December 1990.

To correct the problem, contact Emerson for a BIOS upgrade.

MORE INFORMATION

This problem occurs because the BIOS startup code places a non-zero value that does not point to an interrupt service routine in the INT 5Ch vector. As a result, when standard mode starts up and calls INT 5Ch to try to detect the presence of NetBIOS, the machine hangs. If a NetBIOS network in installed on the system, the problem does not occur.
