CHAPTER 4: Hardware Installation

4.2.2.3 Non-Plug-and-Play Systems (Legacy PCs)

The 5250 Plug n Play Adapter Card can be configured in older PCs without Plug-and-Play capability. The Adapter has been shipped with a Configuration Utility, which will allow you to select the system resources in these systems.

In older systems, all resources for this adapter are set by the DOS 5250 configuration program (DCFG5250) program. The adapter is not enabled until the Enabler (ENB5250) program is executed. When running the IBM emulation program or IBM adapter handler with PC Support, you must use the Configuration Utility and Enabler.

NOTE

The DCFG5250 program will enable the user to configure the 5250 Plug n Play Adapter Card and will attempt to identify potential conflicts; however, since non-PnP systems do not have a resource manager, you must take care to prevent conflicts. Online help provided on the Windows Utility diskette contains information about some typically used PC resources and will help prevent conflicts.

4.2.2.4 MS-DOS and Windows 3.1 Configuration

Since MS-DOS®and Windows 3.1 do not contain integral PnP support, an external system resource manager must be used. In PnP systems, this resource manager will most likely be shipped with the PC. The resource manager will automatically detect the 5250 Plug n Play Adapter Card and assign its resources. While the functions performed by a system resource manager are well-defined, the interfaces that the various managers present vary, and it is therefore impossible to describe each one in this manual. In non-PnP systems, you must execute the ENB5250 program when the PC is started and use the DCFG5250 program to configure the Adapter.

With either PnP or non-PnP systems, the CEM5250.386 Virtual Device Driver (VxD) should be used with programs such as the IBM Client Access/400 or Personal Communications AS/400. This will provide for seamless operation with the 5250 Plug n Play Adapter Card.

4.2.2.5 Windows 95/98 Configuration

In Windows 95/98, the system resource manager, known as the Device Manager, is an integral part of the operating system. Therefore, when running Windows 95/98, the 5250 Plug n Play Adapter Card will automatically be configured. The file CEM5250.VXD is installed by Windows 95/98 the first time it sees the 5250 Plug n Play Adapter Card and will provide the interface between Windows 95/98 and the adapter. There are no resource configuration requirements.
