Supported Components

The following components of Windows 3.0 are supported and available within the OS/2 V2.0 Windows kernel:

Windows real mode kernel (WINOS2.COM and KERNEL.EXE)

Modified Windows standard mode kernel (OS2K286.EXE)

Modified DOS Extender (VDPX.SYS)

Print Manager (Spool Function)

Program Manager:

Permits the starting of multiple Windows applications in a VDM
Permits switching between Windows applications in the VDM

Help Manager

Video device drivers

Keyboard, mouse and communications device drivers

Task Manager

Windows user and GDI DLLs

Printer device drivers

Clipboard support

Note: This is really not necessary to do if you are already running any network requester code under OS/2 itself. This would be transparent to the entire system and therefore every VDM and WIN-OS/2 session will have full access to the network, printers, files, etc.

Control Panel, with functions limited to:

Printer Install
Color
Fonts
Sound
Mouse
International
KBD (Keyboard rate).

The Clock program is available in a Multiple Application VDM (MAVDM) (see Methods of Execution).

The following Microsoft Windows 3.0 components are not included within OS/2 V2.0 (even though they would run just as any other Windows application):

File Manager

Systems Editor (SYSEDIT)

Games

Write

Terminal

Notepad

Cardfile

Calendar

Calculator

PIF Editor

Paintbrush

Recorder

Wallpaper bitmaps

For each of these functions, equivalent capabilities are provided by OS/2 Version 2.0, or these functions are not required within the OS/2 Version 2.0 environment.

Multimedia Extensions (MME) for Windows

Multimedia Extensions for Windows can be installed under WIN-OS/2 and are fully supported.

Some multimedia applications may require more than the default DPMI memory. If that happens, the WIN-OS/2-Setting DPMI_MEMORY_LIMIT should be adjusted to the appropriate value.
