ABOUT THE ABOVE BOARD PC

  The Above Board PC is a memory expansion board for IBM PC's, XT's, and
  compatibles running at 4.77MHz.  The Above Board PC can provide
  conventional and expanded memory in these systems.

  The Above Board PC are NOT COMPATIBLE with 80286, i386CPU-, and i486CPU-
  based computers and many TURBO XT compatibles.  The Above Board PC was
  designed to work at a speed of 4.77MHz like the original IBM PC and XT.

  These installation instructions assume that you are using the Above
  Board installation software dated 6/90 or later.  The latest Above Board
  software is always available on the Intel BBS for anyone to download.

ADDING MEMORY TO THE ABOVE BOARD PC

  You can use either 64K-bit chips or 256K-bit chips on the Above Board
  PC, but you can't use both types at the same time.  For a list of chips
  that Intel has verified, refer to FaxBack Document #1014, "Classic Above
  Board Memory Chip Compatibility."

  You need to use 200-nanosecond chips or faster, (such as 150ns or 120ns,
  etc).  You must fill each column to which you add chips, (nine chips to
  a column).  Leave no partially filled columns.  Fill the columns in the
  order shown in the following diagrams.

SWITCH SETTINGS FOR THE ABOVE BOARD PC

  Switches on the Above Board PC determine the size of memory chips being
  used, the starting address of conventional memory supplied by the Above
  Board if it is filling to 640K, and the I/O address that the Above Board
  will use.

CHANGING SYSTEM BOARD SWITCH SETTINGS, (IBM PC ONLY)

  If you have an IBM PC and are using the Above Board PC or PS/PC to
  provide conventional memory, you need to set switches on the computer's
  system board.  If you don't add conventional memory with the Above
  Board, you don't have to change the computer's switches.

  The following figures show the settings for IBM PC-1s and PC-2s if the
  Above Board provides conventional memory up to 640K bytes:
                 Ŀ
  PC-1 (640K)    ܳܳܳܳ      Note: The PC-1 ROM BIOS allows
                         544K bytes maximum.

  PC-2 (640K)    ߳ܳ߳߳ܳ   
  or PC-1 with   
  upgraded BIOS   1 2 3 4 5 6 7 8

  NOTE:   PC-2s have a "B" stamped on their back panel, PC-1s do not.

SETTING UP EXPANDED MEMORY

  The SOFTSET program will install the software necessary for EXPANDED
  memory.  SOFTSET copies necessary files to your system disk and adds
  commands to your CONFIG.SYS and AUTOEXEC.BAT files.

  You must be using DOS 3.0 or later to run SOFTSET.  SOFTSET must be run
  from a floppy disk.  SOFTSET saves your original CONFIG.SYS and
  AUTOEXEC.BAT files under the names CONFIG.OLD and AUTOEXEC.OLD.

  To start SOFTSET, boot your computer to a plain DOS boot disk that
  doesn't have a CONFIG.SYS or AUTOEXEC.BAT file on it.  This is to ensure
  that no TSR's or other programs are loaded that may interfere with
  SOFTSET.  Insert your Above Board Installation diskette into drive A and
  at the DOS prompt type

  A:SOFTSET <enter>

  Follow SOFTSET's directions and answer the questions, SOFTSET does the
  rest.

  SOFTSET will add the device driver EMM.SYS to your CONFIG.SYS file.  If
  you chose to install the RAM disk on the SOFTSET installation options
  menu, the device driver QUIKMEM2.SYS will be added to the end of your
  CONFIG.SYS file.  If you chose to install the print buffer, the command
  QUIKBUF2 will be added to your AUTOEXEC.BAT file.

EMM.SYS DRIVER PARAMETERS, ABOVE BOARD PC AND PS/PC

  The SOFTSET program will automatically install the EMM.SYS Expanded
  Memory Manager device driver and its parameters.  The parameters are
  given here so that you can manually install the software and manipulate
  the page frame address in cases where there is a memory conflict with
  other add-in boards in the system.

  Please remember, these parameters are for the drivers from the LATEST
  Above Board Installation Software dated 6/90 or later with EMM.SYS rev
  4.0D.  The latest Above Board Installation Software is always available
  on the Intel BBS for downloading, ph. (503) 645-6275.

  EMM.SYS:
  To use expanded memory on your Above Board PC or PS/PC, the EMM.SYS
  command line must be the FIRST line in your CONFIG.SYS file:

  DEVICE=EMM.SYS PC i/o-address [EXPF=x] [ND] [NP] [VI]

  The order of the parameters does not matter.  The parameters are
  separated by a space and they can be in upper or lower-case.

  i/o-address, (2x8, REQUIRED PARAMETER)
  The "i/o-address" parameter specifies which base I/O address the Above
  Board will occupy.  This should match the I/O address set with switches
  on the Above Board.  The I/O addresses of other Above Boards providing
  expanded memory should also be included.  Assign a unique I/O address to
  each Above Board.  No boards in your computer can share I/O addresses.

  Below is a list of valid I/O addresses for the Above Board PC and PS/PC:
  I/O Address
     208
     218
     258
     268
     2A8
     2B8
     2E8

  EXPF= (EXPanded First, OPTIONAL PARAMETER)
  The EXPF= parameter specifies the beginning of the 64K-byte page frame
  needed for LIM 4.0 expanded memory.  The following values are valid:

  EXPF=C400
       C800
       CC00
       D000
       D400 
       D800
       DC00
       E000

  Example:  You're installing the Above Board in an IBM XT. The Above
  Board is using I/O address 258.  You want EMM to begin looking for an
  available page frame in reserved memory that is not in use by other add-
  in boards. In this example we'll imagine the other add-in boards are
  using reserved memory addresses C000 to C7FF.  The EMM.SYS command line
  would read:

  DEVICE=EMM.SYS PC 258 EXPF=C800

SETTING UP RAM DISKS

  QUIKMEM2.SYS:
  To set up a RAM disk in expanded memory, add this line to the end of
  your CONFIG.SYS file.

  DEVICE=QUIKMEM2.SYS x

  The "x" parameter specifies the size of the RAM disk in K-bytes and must
  be at least 16.  Values that are not multiples of 16 will be rounded up
  to the next higher multiple of 16.  The maximum size of the RAM disk is
  8M-bytes, (8192K).

  Example:  To install two 512K RAM disks in expanded memory, add the
  following two lines to the end of your CONFIG.SYS file:

  DEVICE=QUIKMEM2.SYS 512
  DEVICE=QUIKMEM2.SYS 512

  The drive letter assigned to each RAM disk is displayed when the
  computer is started.  There are no parameters to manually assign a
  different drive letter to the RAM disk(s).  DOS automatically assigns
  the next available drive letter to the RAM disk(s).

SETTING UP A PRINT BUFFER

  QUIKBUF2.COM:
  To set up a print buffer in expanded memory, the following line must be
  added to your AUOTEXEC.BAT file:

  QUIKBUF2 PC x d t

  The "x" parameter specifies the size of the buffer in K-bytes and must
  be 32 or greater.  Any value that is not a multiple of 16 is rounded up
  to the next higher multiple of 16.  16K of the print buffer is reserved
  for the pop-up menu.

  The "d" parameter specifies the type of display adapter your computer is
  using.  Choices for the "d" parameter are:

  M    - IBM Monochrome Adapter
  H    - Hercules Monochrome Graphics Adapter
  G    - CGA adapter
  E    - EGA adapter
  V    - VGA adapter
  O    - Other adapter:  Used if the pop-up menu isn't being displayed
       properly.  The "O" parameter disables the print buffer command
       menu but the print buffer will still work.

  The "t" parameter indicates the type of port to be buffered.  Valid
  choices are:

  P    - Parallel port, (LPT1, LPT2, LPT3)
  S1   - Serial port, (COM1)
  S2   - Serial port, (COM2)

  If you choose "P", the first parallel port you print to will be the
  buffered port.  If you omit the "t" parameter, the print buffer defaults
  to parallel.

  Example:  To create a 256K print buffer in expanded memory on an IBM XT
  with an IBM Enhanced Graphics Adapter, and you want to buffer the first
  parallel port you print to, use the following command:

  QUIKBUF2 PC 256 E P
