o DWDOS386 for Intel systems with 80386 and 80486 processors

PC DECwindows Motif requires additional extended memory over and above

the conventional, EMS, and XMS memory required by the other components

of the PATHWORKS for DOS product.

A minimum of 1 MB of system memory must be free and accessible to start

PC DECwindows Motif after configuring the system with the required PATH-

WORKS network components. This memory may be made up of free conven-

tional and extended memory.

Between 1 MB and 4 MB of system memory must be free and accessible to

run X Window System applications. The specific amount of X Server mem-

ory required will depend on the memory requirements of the applica-

tion(s) chosen by the user.

Depending on the number of X Window System applications being displayed

and the memory requirements of each application, the user should test

these types of configurations with PC DECwindows Motif prior to pro-

duction use.

Two utilities that report the amount of memory available to the X Server

are provided:

o DWINFO2 is for Intel systems with 80286, 80386, and 80486 proces-

sors and reports the amount of memory available to DWDOS286.

o DWINFO3 is for Intel systems with 80386 and 80486 processors and

reports the amount of memory available to DWDOS386.

Because PC DECwindows Motif includes its own extended memory manager,

it will conflict with expanded memory managers that do not support the

Virtual Control Program Interface (VCPI), eXtended Memory Standard (XMS),

or the DOS Protected Mode Interface (DPMI) specification. PC DECwin-

dows Motif may also conflict with other drivers using extended mem-

ory, such as disk caching programs and RAM drives, if their presence

cannot be detected by the PC DECwindows Motif extended memory manager.

DWDOS386 does not support DPMI.
