RampagePlus 286                                     AST Part Number 202247-001

The RampagePlus 286 is a memory expansion adapter for the IBM PC/AT and 100%
compatibles running at up to 10MHz.  Memory can be expanded on this board from
512K to 8MBytes using industry standard 256K or 1024K Single In-Line Memory
Modules (SIMMs)  Memory standards supported by the RampagePlus 286 include
conventional (base 640K), linear extended, LIM 3.2, LIM 4.0, and EEMS.  The
RampagePlus 286 can also support Parallel and Serial I/O with an optional
Daughterboard (AST Part No. 500560-002).

Configuration of this board is achieved through "smart switch" technology.
Software is required to set such options as starting address, linear memory
installed, parity enable, etc.  The program required is on the RampagePlus 286
Utilities Disk (AST Part No. 910316-001).


MEMORY CONFIGURATION

    Speed requirements for the SIMM Modules will vary depending on the BUS
    speed of the system:

        BUS SPEED
        6/8MHz  10MHz
        ------  -----
        120NS   100NS

    The RampagePlus 286 will accept either 256K or 1024K SIMMs.  A bank of
    memory would consist of two modules; installing a single module will cause
    errors.  There are four banks available to populate, and if 256K and 1024K
    modules are both used, the 256K modules must be installed in the lower
    numbered banks.  A list of valid configurations follows:

        BANK1  BANK2  BANK3  BANK4    TOTAL MEMORY
        -----  -----  -----  -----   --------------
         512K    -      -      -      512K (0.5 MB)
         512K   512K    -      -     1024K (1.0 MB)

         512K  2048K  2048K    -     4608K (4.5 MB)
         512K   512K  2048K  2048K   5120K (5.0 MB)
        2048K  2048K  2048K    -     6144K (6.0 MB)
         512K  2048K  2048K  2048K   6656K (6.5 MB)
        2048K  2048K  2048K  2048K   8192K (8.0 MB)

        NOTE: 512K = TWO 256K  SIMM MODULES
             2048K = TWO 1024K SIMM MODULES


JUMPER SETTINGS

    JP1 - Change Configuration

    This is a three-pin jumper.  Every time the SMART.COM program is run in
    "automatic" mode, the jumper must be reversed (ie change plug from pins
    1&2 to 2&3 or vice-versa)  This change is not neccesary if the board is
    configured in "manual" mode by SMART.

    JP2 thru JP5 - Board Identification





    If more than one "smart switch" adapter is installed in one system, each
    board must have a unique identification in order to be recognized by the
    configuration software.  The default setting (JP2) identifies the
    RampagePlus 286 as the first "smart" board in the system.  JP3 would be
    the second board, JP4 the third, and JP5 the fourth.
