5.3.2 Troubleshooting Windows 3.1
This section provides troubleshooting tips for users having problems
installing or using the high resolution drivers for Windows 3.1 only.
Problem: When changing resolutions by running SETUP, the SETUP
menu displays more than one selection for the same resolution mode.
Solution: When upgrading to a new set of Windows drivers, you need to
delete the old OEM?.INF(e.g. OEMO.INF) file in the WINDOWS\SYSTEM
subdirectory. The SETUP menu will then display only one selection for
each resolution mode.
