Modifying CONFIG.SYS
so there is not usually any need to use EXCLUDE. The area F000-FFFF is always
occupied by system ROM.
INCLUDE = xxxx [-cccc]
Specifies the memory to be included under the control of the driver. Parameters are
similar to the EXCLUDE option above. For example, if an EGA video adapter is
installed in the computer, the monochrome graphics section of memory might not be
used. So INCLUDE B000-B7FF would allow the driver to make use of this area of
memory.
Note: If you are editing the command line yourself, the EXCLUDE and INCLUDE
options may be used several times to exclude or include several areas of
memory, though at least 64KB of memory above 640KB (A000) should
remain. The facility is not available using the setup program. If you specify
the same area of memory in an EXCLUDE and an INCLUDE statement, the
command line order determines which statement will take effect.
FRAME = aaaa
Specifies the page frame starting address (i.e., a contiguous 64KB segment through
which the Expanded memory is mapped). The parameter aaaa must be one of the
following values: C000, C400, C800, CC00, D000, D400, D800, DC00, or E000.
Specifying FRAME overrides the automatic choice of page frame. If you need to
specify a frame address, try D000, which uses the range D000-DFFF. The D range is
usually available.
IOADDR = aaaa
Overrides the default base I/O address at which the EMS hardware should be
configured. The parameter aaaa must be one of the following values: 0208, 0218,
0258, 0268, 02A8, 02B8, or 02E8. The default is 0208 (hex). You should not change
this unless you are sure that you have a conflict with another card.
SCAVENGE = xxxx [-cccc]
Specifies an area of system shadow RAM in the range A000-FFFF to be used for EMS
memory. Normally, the shadow RAM is used to overlay system ROM regions, for the
purpose of speeding up code execution from those areas. Not all of the shadow RAM
is used, however. The areas that are not used may be scavenged for use as EMS
