 INTRODUCTION

     This document contains all the information an experienced user needs to
     install an Above Board 2 and its software.  If you're not an
     experienced user, you should use the Above Board manual for
     installation instructions or have your dealer install the Above Board.

 ADDING MEMORY TO THE ABOVE BOARD 2

     The Above Board 2 uses Single Inline Memory Modules (SIMMs).  These are
     small circuit boards generally containing nine memory chips each.  The
     Above Board 2 uses 256K-byte SIMMs only; it can't use 1M-byte or 4M-
     byte SIMMs.  For a list of SIMMs that Intel has verified, refer to the
     Above Board manual or to FaxBack Document #1510, "Micro Channel Above
     Board Memory Chip Compatibility."

     You must install two SIMMs at a time, filling sockets 1 and 2 first,
     then 3 and 4, etc.  The following figure shows where the sockets are on
     the Above Board.

     *   You can use SOFTSET to set the Above Board 2 for zero wait-state
         operation under DOS.  You must use only 100ns or faster memory
         modules when running at zero wait states.  Set switch one ON only
         if you're using an operating system other than DOS AND you need
         zero wait-state operation.

 CONFIGURING THE SYSTEM

     You MUST configure your PS/2 computer with the backup copy of the
     Reference Diskette after installing an Above Board or adding more
     memory to the Above Board.  Insert the Above Board then follow these
     instructions.

     Turn on your computer and put the Reference Disk in drive A.  Answer Y
     when asked "Automatically Configure System?".  After configuration is
     complete, remove the Reference diskette from drive A, and restart the
     computer.

 INSTALLING THE SOFTWARE

     Installing the Above Board software involves these steps:

        Copying files
        Setting up expanded memory
        Setting up RAM disks
        Setting up a print buffer

     These steps can be done manually or can be done by the SOFTSET program.

 COPYING THE FILES

     Copy the files you need from the Intel diskette to your hard disk's
     root directory or to your system diskette. This can be done manually or
     with the SOFTSET program. If you are manually installing expanded
     memory the files you may want to copy are:

     EMM.SYS         If you want the Above Board 2 to provide expanded
                    memory.
     QUIKMEM2.SYS   If you want to set up a portion or your expanded memory
                    as a RAM Drive.
     QUIKBUF2.COM   If you want to set up a portion of your expanded memory
                    as a print buffer.

 SETTING UP EXPANDED MEMORY

     To use expanded memory, add this line to your CONFIG.SYS file:

     DEVICE = EMM.SYS c [EXP=x] [ND] [NP] [NE] [H=x] [FR] [MC]
                        [RD] [MCF=x] [MCL=x] [EXPF=x] [EXPL=x]

     Where the parameters without brackets ([]) are required, and those with
     brackets are optional.

 REQUIRED PARAMETERS

          c          specifies the type of computer you're using.  Valid
                    values:

         MOD60     IBM PS/2 Model 60
         NC        Non-compatible computer*

     If you specify "NC" as the computer type, EMM error recovery features
     will be disabled.  The ROM BIOS will report parity errors.

                 all memory on the computer's system board and

 SETTING UP A RAM DISK

     To use a RAM disk, add this line to your CONFIG.SYS file:

           DEVICE = QUIKMEM2.SYS x

     Where "x" specifies the size of the RAM disk in K bytes.   The value
     for "x" must be at least 16 and can't exceed the total amount of
     expanded memory in the computer.  Values that aren't multiples of 16
     are treated as the next higher multiple of 16.  You don't need to type
     a "K" after the number.

 SETTING UP A PRINT BUFFER

     To use a print buffer, add this line to your AUTOEXEC.BAT file:

        QUIKBUF2 c SIZE=x d t

     All parameters are required.

 IF YOU HAVE PROBLEMS

     If you receive error messages during installation that say, "One or
     more of the parameters are missing or invalid...", you probably have an
     early version of the Above Board software.  You can get the latest
     software by contacting Intel's Customer Support or by using your modem
     to download the software from the Intel BBS.
