Loss of CMOS Settings When Rebooting on Intel Machines

ID: Q83892

The information in this article applies to:

Microsoft Windows versions 3.1, 3.11

SUMMARY

Some Intel machines require a BIOS update if the CTRL+ALT+DEL key combination causes the CMOS settings to be erased when EMM386.EXE is loaded. This problem only occurs with HIMEM.SYS version 3.07 and EMM386.EXE version 4.44, which shipped with the Microsoft Windows operating system version 3.1.

According to Intel, this is a known BIOS problem and can be fixed with a BIOS update.
