ABOVE BOARD 286 & PS/286 INSTALLATION

         INTRODUCTION
         
  This document contains all the information an experienced user needs to
  install an Above Board 286 and PS/286 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.

  The Above Board 286 is designed to operate in 8-bit IBM PCs, PC XTs, and
  compatibles, 16-bit IBM PC ATs and compatibles, and 80386-based
  computers with bus speeds of up to 12 MHz.

         THE PC SELECTION CHIP
         
  For 8-bit systems, you must install the PC selection chip in U111 socket
  located above the gap between the two bus connectors (see figure).
  Don't install the PC Selection chip for 16-bit systems.

             Ŀ
                                                               
                                                               
                                                               
                                                               
                                             Ŀ          
                                        U111

                                                 Bus Connectors

  If you can't find the PC selection chip, contact Intel's Customer
  Support.

         ADDING MEMORY
         
  You must use 256K-bit chips on the Above Board 286.  You can't use 64K-
  bit chips.  For a list of chips that Intel has verified, refer to the
  Above Board manual or to FaxBack Document #1014, "Classic Above Board
  Memory Chip Compatibility."

  You must fill two columns at a time.  Add the chips to the Above Board
  in the order shown in this figure:

                 Ŀ
                                                  
                                                  
                                                  
                                                  
                 Ŀ    ڿ        
                  8  7  6  5  4  3  2   1  

         ADDING PIGGYBACK MEMORY OPTION BOARDS
         
  You can use Piggyback Memory Option boards to add memory to your Above
  Board 286.  There are two different piggyback boards available:  a 2M-
  byte version that uses the same 256K-bit chips as the Above Board, and a
  6M-byte version that uses 1M-bit chips.  For a list of chips that Intel
  has verified, refer to the Above Board manual, to the Piggyback Option
  Manual, or to FaxBack Document
  #1014, "Classic Above Board Memory Chip Compatibility."

         RUNNING SETBOARD
         
  The SETBOARD program lets you configure the Above Board 286. To run
  SETBOARD, insert the Above Board diskette into drive A, type A:SETBOARD,
  then hit the ENTER key.  Any time you need help answering a question
  displayed on the screen, press the F1 key for help.

         AUTOMATIC SETUP
  Use this option when you want the Above Board 286 to fill conventional
  memory (in systems with less than 640K) and use the rest of its memory
  as expanded memory.
        MANUAL SETUP
  Use this option if you need to do any of the following:

      Use Above Board memory as extended memory (16-bit systems only)
      Set Expanded Memory I/O Port to other than 258h
      Set the Serial or Parallel port address (Above Board PS/286 only)
      Set the computer's Bus Speed faster than 6 to 8MHz (16-bit systems
       only)
      Set Memory Chip Speed to other than 150ns

         SYSTEM BOARD SWITCH SETTINGS FOR IBM PC
         
  If you have an IBM PC and use the Above Board 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.
                  1 2 3 4 5 6 7 8
                 Ŀ
  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 don't.

         RUNNING THE SETUP PROGRAM
         
  Most 16-bit computers don't use switches to set system options. Instead,
  you run a "SETUP" program which saves the system configuration in CMOS
  RAM.  Check your computer's User's Guide for instructions on how to run
  the SETUP program for your computer.

         INSTALLING SOFTWARE
         
  Installing the Above Board software involves these steps:

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

         COPYING FILES
  Copy the files you need from the Intel diskette to your hard disk's root
  directory or to your system diskette.

         SETTING UP EXPANDED MEMORY
  To use expanded memory, add this line to your CONFIG.SYS file:

               DEVICE = EMM.SYS c m i [EXP=x] [ND] [NP] [H=x]

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

      i       Specifies the I/O address the Above Board uses   
              to access expanded memory.  Valid values:

  ͵
   EXP=x      Lets you verify the amount of expanded memory in 
              the computer.  "x" specifies the total expanded  
              memory amount.  EMM generates an error message   
              if it finds an amount different from what you    
              specified.                                       
  Ĵ
   ND         Instructs EMM to run abbreviated memory tests

  Ĵ
   NP         Instructs EMM not to pause after EMM errors or   
              messages.                                        
  Ĵ
   H=x        Sets EMM Handle count to "x" ("x" must be less   
              than 256).                                       
  

         SETTING UP RAM DISKS
  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 x d t

  Ĵ
      x       Specifies the size of the buffer in K bytes and  
              must be 32 or greater.  Any value that isn't a   
              multiple of 16 is treated as the next-higher     
              multiple of 16.                                  
  Ĵ
      d        Specifies the display adapter your computer

                 G   IBM CGA                  O   Other        
  Ĵ
      t        Specifies the type of port to be buffered.      
               Valid values:                                   
                                                               
                     P   Parallel                              
                     S1  COM1                                  
                     S2  COM2                                  
  

         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.
