Gpf

In Microsoft Windows 3.1, what causes frequent GPFs (General Protection Faults)?

The problem may be with the areas of memory Microsoft Windows 3.1 is trying to access. If you are experiencing frequent Windows 3.1 crashes, try starting Windows with this command:

  win /d:xsv

If the GPFs do not appear, in your system.ini file, under the "386Enh" section, add the following line:

  VirtualHDIRQ=off

If the GPFs continue, try starting Windows with this command:

  win /d:xs

If the GPFs do not appear, in your system.ini file, under the "386Enh" section, add the following line:

  SystemROMBreakPoint=false

If the GPFs continue, try starting Windows with this command:

  win /d:x

If the GPFs do not appear, in your system.ini file, under the "386Enh" section, add the following line:

  EMMExclude=A000-EFFF

While this should get Windows running more reliably, you should try to narrow down the range of memory that actually has to be excluded.
