INSTALLING EMM.SYS
================================================================================
NOTE: IF YOU HAVE AN ABOVE BOARD 2 FOR THE IBM PS/2 MODELS 50 AND 60,
SEE THE SECTION BELOW TITLED "INSTALLING EMM2.SYS."
This section explains the installation of EMM 4.0, which is the
expanded memory manager for the Intel Above Board. You should
follow the installation instructions provided with your Above
Board before installing the EMM.SYS software.
Once you have installed the Above Board hardware, you can either
run the MEMSET program, which can be found on the Utilities 2 Disk,
or by following the detailed steps outlined below.
Installing the software without using MEMSET involves two steps:
o Copying EMM.SYS from the Utilities 2 Disk.
o Editing your CONFIG.SYS file to include a "device" command
line for EMM.SYS.
Copying files
-------------
Before you can use the Above Board for expanded memory, you must
copy EMM.SYS from the Utilities 2 Disk to your fixed disk.
Setting up Expanded Memory
This section explains how to edit the CONFIG.SYS file to use
EMM 4.0. To use EMM 4.0, you'll need to add new commands to
your CONFIG.SYS file. Use any ASCII file editor (such as
EDLIN or Notepad) to view and edit the file. Then perform the
following steps to add the commands:
1 Copy the parameters (for example, M5 and I5) that are currently
on the DEVICE=EMM.SYS line.
If you'll write down these parameters now, you won't need to
remove your computer's cover to see your Above Board's switches.
You can use the old parameters to help you choose the new parameters.
2 Replace the DEVICE=EMM.SYS line in your CONFIG.SYS file with the
following new parameters:
DEVICE=EMM.SYS Computer Memory_Address I/O_Address [EXP=x] [ND] [NP] [H=x]
The first three parameters, Computer, Memory_Address, and I/O_Address,
are required for using expanded memory; the parameters in brackets []
are optional (note: you don't type the brackets). Be sure you have
only one DEVICE=EMM.SYS line in your CONFIG.SYS file.
The "Computer" parameter defines the type of computer in which
the Above Board is installed. Replace the "Computer" parameter
with one of the choices listed in Table 2. The "Computer"
parameter is required in the EMM command line.

The "Memory_Address" parameter specifies the address of the
64K-byte block of memory to which expanded memory is mapped.
If your old DEVICE=EMM.SYS line has an M parameter, replace the
old M parameter with the corresponding Memory_Address listed in
o Table 3 (for Above Boards installed in 80286-based computers) or
o Table 4 (for Above Boards installed in 8088- or 8086-based computers).

If you don't have an old DEVICE=EMM.SYS line in your CONFIG.SYS
file, use a memory address listed in Table 5. Be sure you use a
memory address listed for your specific Above Board.
If in doubt of which address to choose, use address D000. The
"Memory_Address" parameter is required in the EMM command line.

The "I/O_Address" parameters specify which I/O addresses Above
Boards use to access expanded memory. Assign a unique I/O
address to each board. No boards in your computer can share I/O
addresses. Use one I/O address for each Above Board with
expanded memory. Piggyback Memory boards don't need I/O
addresses.
If your old DEVICE=EMM.SYS line has an I parameter, replace
the old I parameter with the corresponding I/O_Address listed
in Table 6.

-------------------------------------------------------------------
If you don't have an old DEVICE=EMM.SYS line, use an I/O address
listed in Table 7. Be sure your "I/O_Address" parameter values match
the I/O addresses you selected when you set your Above Board switches
( see the set up instructions in your Above Board documentation ).
If in doubt, use the addresses at 208 or 258. The "I/O_Address"
parameter is required in the EMM command line.

-------------------------------------------------------------------
Example. You're using two Above Board 286s in an IBM PC AT.
You're installing expanded memory at D000. One board is set for
I/O address 208 and the other for 258. Use this command:
DEVICE=EMM.SYS at D000 208 258
The EXP=x (expanded memory amount) parameter lets you verify
the amount of expanded memory in your computer, where x is the
amount in kilobytes. The value for x must be a multiple of 16
and less than or equal to 32768.
The EXP=x parameter is optional. If this parameter is in the
command line, the EMM compares the number you specify (for
example, EXP=512 for 512K bytes) with the amount of expanded
memory it finds. If the numbers aren't the same, you'll receive an
error message.
The ND (no diagnostics) parameter tells the software to run abbreviated
memory tests after a warm boot (Ctrl-Alt-Del). The ND parameter is
optional. If ND is in the command line, the EMM will run abbreviated
memory tests; if ND is absent, the EMM will run full tests. In either
case, full tests are run during a cold boot (power-on).
The NP (no pause) parameter lets you set the EMM so that it
does not pause after an EMM error or advisory message.
The NP parameter is optional. If NP is in the command
line, the EMM won't pause after errors or messages.
If NP is absent, the EMM will pause.
The H=x (handle count) parameter lets you set the EMM to
support as many handles as a particular application program needs.
A handle is a value that the EMM assigns and uses to identify a
block of memory requested by an application program. The EMM
allocates memory based on the number entered. Specifying a
small EMM handle count can save conventional memory and allow
EMM to run faster.
The EMM handle count default is 64 handles. Application
programs written to use EMM versions below EMM 4.0 use a
maximum of 32 handles. If you're using older application
programs, you may change the EMM handle count to H=32,
but using the default of 64 handles will work fine. The maximum
number of handles is 254.
The H=x parameter is optional. If the H=x parameter is in the
command line, the EMM will support the number of handles
specified by x. The handle count will appear on the screen when
EMM is installed. If H=x is absent, the EMM uses 64 handles.
You won't see a handle count on the screen when EMM is installed.
Example. You're using one Above Board 286 in an IBM PC AT.
Expanded memory is installed at D000. The board is set for I/O
address 208. You have 1.5M bytes of expanded memory and no
extended memory. You want abbreviated diagnostics and your
application program uses 128 handles. Use this command:
DEVICE=EMM.SYS at D000 208 EXP=1536 ND H=128
When you have finished editing the CONFIG.SYS file, reboot
your computer. EMM 4.0 is installed and ready to go.
================================================================================
INSTALLING EMM2.SYS
================================================================================
Once you have installed the Above Board 2 in your PS/2 Model 50 or
60, you can run the MEMSET program provided on the Utilities 2 Disk
or use the detailed instructions below.
Installing the software involves two steps:
o Copying EMM2.SYS from the Utilities 2 Disk.
o Editing your CONFIG.SYS file to include a "device" command
line for EMM2.SYS.
Copying files
-------------
Before you can use the Above Board for expanded memory, you must
copy EMM2.SYS from the Utilities 2 Disk to your fixed disk. When
you copy the file, you should rename the file emm.sys, for example:
COPY A:\EMM2.SYS C:\EMM.SYS
Setting up Expanded Memory
This section explains how to edit the CONFIG.SYS file to use
EMM 4.0. To use EMM 4.0, you'll need to add new commands to
your CONFIG.SYS file. Use any ASCII file editor (such as
EDLIN or Notepad) to view and edit the file. Then perform the
following steps to add the commands:
1 Copy the parameters that are currently on the DEVICE=EMM.SYS line.
2 Replace the DEVICE=EMM.SYS line in your CONFIG.SYS file with the
following new parameters:
DEVICE=EMM.SYS Computer EXP=x ND NP NE FR MC RD H=x MCF=x MCL=x EXPF=x EXPL=x
All the parameters are optional.
The "Computer" parameter defines the type of computer in which
the Above Board 2 is installed. Replace the "Computer" parameter
with one of the choices listed in Table 2.

The EXP=x (expanded memory amount) parameter sets the amount
of expanded memory in your computer, where x is the amount
in kilobytes. The value for x must be a multiple of 16 and
less than or equal to 32768. Any unused memory in your system
will be used as extended memory. The default is x=0, which means
that NONE of your memory will be used as expanded memory.
ND (no diagnostics) - see the EMM.SYS documentation above.
NP (no pause) - see the EMM.SYS documentation above.
NE (no extended memory device drivers) - Use this option if you
don't intend to use any extended memory. Do NOT use this option
if you intend to use HIMEM.SYS.
The FR (fast RAM) parameter tells emm to take advantage of 100-
nanosecond SIMMS installed in the Above Board 2. Do not use this
if you have any 120 nanosecond SIMMS installed in your Above Board 2.
The MC (mappable conventional memory) parameter causes emm to
disable all memory on the computer's system board. You should
only do this if you have 2 mb or more of expanded memory.
The RD (relocate driver) parameter causes emm to be installed in
expanded memory instead of conventional memory. This conserves
conventional memory.
H=x (handle count) - see above.
The MCF=x (mappable conventional first) and MCL=x (mappable
conventional last) parameters provide the same function as the
MC parameter, but they also let you override the beginning and
ending addresses of mappable conventional memory.
The EXPF=x (expanded first) and EXPL=x (expanded last) parameters
specify the addresses of the expanded memory page frame.
Example. You're using an IBM PS/2 Model 50 that includes an
Above Board 2 card with 2 megabytes of memory. You want to
leave 64K of extended memory for HIMEM.SYS, map all of conventional
memory, and use the remainder as expanded memory.
