7/9/98 Using ROM-DOS 6.22 2-31
xxxx-yyyy defines a range of memory to fill-in with extended memory.
Up to eight ranges can be specified. The range can be specified as
an exact range, for example D000 to DFFF; or as the starting and
ending marks for the range, D000 to E000. In either of these
examples, 64K has been defined.
Frame defines the starting segment for four 16K pages which can be
mapped in and out at will. memK specifies how much memory to
reserve for EMS, the default allocates all XMS memory for use as EMS.
D= specifies the amount of RAM in Kbytes (specified as a base 10
number) to be reserved for a VDS buffer (Virtual DMA Services). The
default value is zero.
ROM= specifies a region of ROM to be supported by shadow RAM.
This uses write protected RAM in place of ROM and can increase the
speed of some systems.
