Fraser's Hill: Technical Note: EMM386.EXE

EMM386 Parameters

The Fraser's Hill FHL-7124, FHL-7135, FHL-7121, FHL-8124, FHL-8135, and FHL-8121 adapter boards use two 16KB memory blocks in the adapter area of low memory. It is necessary to exclude this memory from use by expanded memory managers and other programs. Note: the examples use the default board switch settings. Substitute the correct values if the memory address switch has been changed from the default settings.

Add the parameter

        X=D000-D7FF

to the existing device=emm386.exe entry in config.sys.

before:

        DEVICE=EMM386.EXE NOEMS

after:

        DEVICE=EMM386.EXE NOEMS X=D000-D7FF

before:

        DEVICE=EMM386.EXE RAM X=A000-C7FF

after:

        DEVICE=EMM386.EXE RAM X=A000-C7FF X=D000-D7FF
