The information in this article applies to:

Microsoft Windows operating system 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.

MORE INFORMATION

To obtain an updated BIOS, call (800) 468-3548 (INTEL4U). You can also obtain the update from Intel's bulletin board at (503) 693-1493. Log on as "guest" (the password). The file is 11031O0.ZIP.

The BIOS must be within the range "Phoenix 85-91 1.10.30.O0" to "Phoenix 85-91 1.10.31.O0" Note: The second to the last character in these numbers is the letter O, not 0 (zero).
