Windows: Masterpiece Requires SYSTEM.INI Modification

• Microsoft Windows operating system versions 3.0, 3.0a

   UniqueDOSPSP=true

MORE INFORMATION

Each time Windows creates a new virtual machine to start a new application, Windows reserves a unique amount of memory (i bytes) below the application. For example, the first application is loaded at address M, the second at address M+i, the third at M+2i, etc. The amount of memory (i) is determined by the PSPIncrement setting. This setting helps assure that applications in different virtual machines all start at different addresses.

Some networks use applications' load addresses to identify the different processes using the network. On such networks, failing to enable this setting might cause one application to fail when you exit another because the network interprets them as the same. However, enabling this setting will leave slightly less memory for non-Windows applications. If you are running a network based on Microsoft Network or LAN Manager, the default value is TRUE. See the NETWORKS.TXT online document to find out whether the network you are running is one of these.
