 MEMORY BOARDS - GENERAL NOTES

     Any memory board added into an 8088-based computer's add-in slot can
     only provide Expanded memory because of the PC's 8 bit bus.

     Inboard 386/PC piggyback options can provide extended memory since they
     don't access the memory across an 8bit bus, but are directly attached
     to the Inboard 386/PC utilizing a 32bit bus.

     The InBoard 386/PC can work faster and do more if a piggyback memory
     card is attached to it (a 4M-byte piggy can be ordered directly from
     Intel by following the instructions in FaxBACK document 9012). The
     piggy will increase the amount of Extended memory and allow the use of
     80386 control programs like QEMM386 (from Quarterdeck) and 386ToTheMAX
     (from Qualitas).

 AST 6-PACK AND 6-PACK PLUS

     Intel has tested these products with the Inboard 386/PC, and they are
     compatible.

     Tech Notes: You must disable any 6-Pack+ memory being used for
     conventional memory because Inboard 386/PC supplies all conventional
     memory for the computer.  To disable the memory on 6-Pack+ boards, set
     switches 4, 5, and 6 to off.  (The 6-Pack+ ports and clock still
     function when its memory is disabled.)  Also disable parity on the 6-
     Pack+ by setting switch 8 off.

 AST 6 PACK PREMIUM

     Intel has Customer reports that this board is compatible with the
     Inboard 386/PC but you must disable conventional memory on the 6 Pack
     Premium.

     To disable conventional memory provided by the 6 Pack Premium set
     switches:

             1 off
             2 on
             3 off
             4 on

 AST RAMPAGE

     Intel has tested this product with the Inboard 386/PC and they are
     compatible.

 AST MEGAPLUS

     You must disable any Megaplus memory used for conventional memory
     because Inboard 386/PC supplies all conventional memory for the
     computer.

     The switch settings that disable memory on the Megaplus board are as
     follows:

                    1 - OFF    5 - ON
                    2 - ON     6 - OFF
                    3 - OFF    7 - OFF
                    4 - ON     8 - OFF

 AST MEGAPLUS 2

     We have one customer report that this board is incompatible with the
     Inboard 386/PC because the conventional memory on the MegaPlus 2 board
     can't be disabled.  The user had to remove the MegaPlus board to
     install the Inboard 386/PC.

 INTEL MEMORY BOARD NOTES

     Inboard 386/PC is compatible with the following Intel Memory boards:

             Above Board PC & PS/PC
             Above Board 286 & PS/286
             Above Board Plus & Plus I/O
             Above Board Plus 8 & Plus 8 I/O
             Matched Memory Classic

     The Inboard 386/PC is NOT compatible with Micro Channel Above Boards or
     the Above Board AT and PS/AT because these memory boards won't work in
     an 8088-based computer with an 8-bit data bus.

     All other Above Boards are compatible as long as the Above Board is
     supplying only expanded memory and the Inboard 386/PC isn't supplying
     expanded memory.  Only one expanded memory manager can be active in a
     computer at a time.

     Because the Inboard 386/PC supplies all of its own conventional memory,
     you must disable any conventional memory the Above Board supplies.

     You can't use Above Boards to supply extended memory in computers with
     an Inboard 386/PC because extended memory requires a 16-bit path to the
     CPU, which can't happen across an 8-bit data bus.  The only way to use
     extended memory is by adding the Inboard 386/PC Piggyback Option.

 TECMAR CAPTAIN BOARD

     This board has limited compatibility with Inboard 386/PC.  The clock
     won't work (date and time are set to 00000) when the Inboard 386/PC is
     set to Speed 4. It will be necessary to start the Inboard 386/PC in
     Speed 1, and then switch it to Speed 4 after the clock driver has been
     installed.
