Memory Savings Techniques

PATHWORKS for DOS software supports several techniques for saving con-

ventional PC memory. By using these techniques, additional conventional

PC memory becomes available for user applications.

o Several network components can be optionally loaded into expanded

memory simultaneously. For 80386 and 80486 Intel processors, the

PC must be configured with a user-supplied Expanded Memory Spec-

ification (EMS), Version 4.0 software driver. For 8088, 8086, and

80286 Intel processors, the PC must be configured with both a user-

supplied EMS, Version 4.0 software driver and hardware.

o The LAN Manager Basic Redirector can be loaded into the High Mem-

ory Area (HMA) portion of extended memory.

The Enhanced Redirector can be loaded into HMA or into Expanded Mem-

ory (EMS). Users should use the Enhanced Redirector to take advan-

tage of the LAN Manager capabilities in conjunction with a PATH-

WORKS for OS/2 server.

The configuration must have a minimum of 64KB of extended memory

(if either redirector is loaded in extended memory) and either the

Digital-supplied driver, HIMEM.SYS, or a vendor-supplied high mem-

ory manager that supports Extended Memory Specification (XMS), Ver-

sion 2.06.

Note: DOS Version 5.0 or Version 6.0 cannot be loaded in the High

Memory Area (HMA) if either the Basic or Enhanced Redirector is al-

ready loaded into the HMA.

o Provides the ability to unload several network components from ei-

ther conventional or EMS memory.

The exact amount of conventional memory available for user applica-

tions will vary depending on:

o Availability and size of EMS drivers
