Normally, you set the amount of
this memory as part of the application??™s PIF. However, the PIF doesn??™t let you control the Expanded
Memory Manager (EMM), which is the application that actually makes the memory accessible. The
EMM entry lets you change how the EMM works. This option uses the following syntax:
EMM = [A=AltRegSets] [B=BaseSegment] [RAM]
The following list describes each of the command line arguments.
A=AltRegSets Defines how many alternative mapping register sets the EMM has available for
mapping memory between extended memory and conventional memory. You can provide any
value between 1 and 255. The default setting of 8 works fine in most cases. Check your application
documentation for additional requirements.
B=BaseSegment Defines the base segment, the location where the EMM places code within the
DOS conventional memory area from extended memory as needed. Generally, any setting you
choose works fine. However, some applications use specific segments for their use. Using the
same memory segment for two purposes causes memory corruption and can cause the application
to fail. The application documentation should tell you about any requirements.
