    N-O - MCP INSTALLATION & SYSTEM CONFIGURATION NOTES: DOCUMENT 3032

         3150                     Intel487 SX
    
            MCP socket is located underneath the keyboard. i487 SX is
    
            automatically enabled.
    
    
    
         PC6                      8087-2
    
            Reports indicate that this computer can't use an Intel Above Board
    
            and the 8087 at same time.  Contact NCR for more information.

            Intel cannot guarantee compatibility with non-Intel
    
            microprocessors.  Contact the your computer's manufacturer for more
    
            math coprocessor compatibility information.
    
    
    
         Portable 386             Intel387 DX
    
            Set jumper near 387 to pins 2-3
    
    
    
         Powermate II             Intel387 DX
    
            The beveled corner on the 387DX socket of this computer is 180
    
            degrees out of place.  However, a tiny arrow on the system board
    
            correctly points toward pin 1 of the 387DX.  Align the beveled
    
            corner of the 387DX with this tiny arrow to correctly install the
    
            chip and avoid damage to the computer or chip.
    
    
    
         NEC Ultralite SL25C      Intel387 SL 
    
            The customer may see the i387 SL-25 Mobile Math CoProcessor fail
    
            the IEEE Conformance Test on our Utilities Diskette, if they don't
    
            have a BIOS revision of 24 or later.  If the  customer's BIOS
    
            revision is earlier than rev 24 have them contact NEC  for an
    
            update.
    
    
    
         Powermate 386/25S        Intel387 DX 
    
            Set Switch 1 to ON, and Jumper JP6 2-3. Pin 1 of MCP socket  is
    
            closest  to base of the ZIF socket lever. System's Hardware Setup
    
            utility must be run to configure the system.
    
    
    
         Powermate 386 (16 MHz)   Intel387 DX 
    
            Jumper pins 2-3. System may fail the Intel Diagnostics Environment
    
            test. This does not effect operation of system.
    
    
    
         Powermate 386 (25 MHz)   Intel387 DX 
    
            Jumper 13G2 or 5L1, Pins 1-2 for Intel, Pins 2-3 of Weitek,  also
    
            DIP switch 1, position 7 should be ON for Intel, and OFF for
    
            Weitek.
    
    
    
         Prospeed 386             Intel387 DX * 
    
            There is a jumper to the left of the MCP socket (when facing  the
    
            front of the system). Set this jumper from position 2-3 to position
    
            1-2.
    
    
    
         Powermate 386 (20MHz)    INtel387 DX * 
    
    
    
            *This machine uses a ZIF (Zero Insertion Force) socket for  the
    
            Intel387 DX. To find the orientation look for a small triangle
    
            silk-screened at one of the socket corners or on the  motherboard;
    
            this is pin 1.

            This accelerator board has problems when using a math coprocessor
    
            and an Above Board.  The problem can be solved  by placing a dummy
    
            chip in the 8087 socket on the system board. Contact Orchid for
    
            more information.  Intel doesn't have a  dummy 
    
            chip for accelerator boards.

         PACKARD BELL
    
    
    
         PB286LP                  Intel287 XL 
    
            Reports indicate that the Packard Bell manual instructs you to set
    
            a jumper for an external clock.  This step is actually unnecessary.
    
    
    
         486SX                    Intel487 SX 
    
            Some units of this model of system shipped with the wrong  BIOS. If
    
            they have the wrong BIOS, the system  reports that a  mcp  is
    
            present in the Intel486 SX. Customer should contact Packard Bell
    
            for a new BIOS. Packard Bell's number is: 800-733-4422.
    
    
    
         PANASONIC  
    
    
    
         1850                     Intel287 XL
    
            Install 10 MHz oscillator (Radio Shack part number AXX- 7149).
    
            Insert into socket Y3 to enable the math coprocessor.
    
    
    
         1925SX                   Intel387 SX 
    
            There is a jumper located next to the microprocessor on the
    
            motherboard, that needs to be set to enable, after you have
    
            installed the math coprocessor. The jumper is marked
    
            ENABLE/DISABLE.
    
    
    
         SAMSUNG 
    
    
    
         386SX-25 Notebook        Intel387 SX
    
            This system uses VLSI chipset. Samsung testing shows ULSI mcp would
    
            not work in this system, while the Intel chip worked  fine.
    
    
    
         SANYO 
    
    
    
         MPC 386DX-16             Intel387 DX 
    
            The Math Coprocessor may be recognized as a 287, when the system
    
            BIOS is v1.04 SE. Replacing this BIOS with v1.04 solves the
    
            problem.
    
    
    
         SHARP 
    
    
    
         MZ100 8086 System        8087 
    
            This system does not have an MCP socket. If the customer sends 8087
    
            and system to Sharp, Sharp hardwires the chip onto the system
    
            board.
