RS232 JUMPER SETTINGS

    The RS232 configuration block is made up of three sets of three pins each.
    Their function is to minimize the need for making special I/O cables for
    some unique serial devices. The normal setting in nearly all cases is to
    install three jumpers connecting the middle and left pin in each row. In
    rare instances, a device may require that the CTS, DSR, or DCD signals be
    forced true. In these cases, move the corresponding jumper to connect the
    center and right pin.

    the "two" positions, allowing normal RS-232 operation. In rare instances,
    a device may require that the CTS, DSR, or DCD signals be forced true. In
    these cases, move the corresponding jumpers to the "one" position.

SixPak 286                                          AST Part Number 202344-001

The AST SixPak 286 board offers flexible and powerful memory enhancement for
the AST Bravo/286, AST Premium/286, AST Premium Workstation, IBM PC/AT and
compatible computers.  It offers complete software compatibility with Expanded
Memory Specification (EMS) 4.0 software.

The SixPak 286 SmartSwitch configuration software eliminates the need to set
board switches. The software can make the optimal settings for your computer
automatically, or you can select your configuration from easy to use menus.
The SixPak 286 board retains your selected configuration even when your
computer is turned off.

You can upgrade your SixPak 286 board's memory to a maximum of four megabytes
(MB) with single inline memory modules (SIMMs) that snap in and out of your
board socket's.  Optional I/O Pak 286 (AST P/N 500560-002) piggyback boards
add one serial port and one parallel port to your SixPak 286 board.


JUMPER SETTINGS

To set the board Identification jumper (E9 through E12): If this is the first
SixPak 286 board in your computer, place the jumper on E9. For the second
board use E10, the third board, E11 and the fourth board, E12. In addition, to
use automatic mode after adding or removing memory, you must set the default
configuration jumper (E8) to the alternate position. This clears the old
configuration. For example, if the jumper is on pins 2 and 3, move it to pins
1 and 2.  Also,the jumper on (E7) should remain installed to enable parity
error reporting. Jumpers (E1 thru E5) tell the SixPak 286 the amount of memory
on the board, for 512K and 1MB the jumpers should be in the 1-2 position, for
2MB and 4MB the jumpers should be in the 2-3 position.

    The above list of addresses is not complete.  After the 3072K
    address, we have listed the settings for every megabyte only.
    Switches 5,6 & 7 determine the addresses between.  If you are
    unable to interpolate the correct starting address from the above
    information, contact AST to order the complete documentation.

    NOTE: The "STARTING ADDRESS" is not the same as "MEMORY INSTALLED
          IN SYSTEM".  Because of the reserved rom area residing
          between A0000h and 100000h, extended memory has a linear
          starting address of 1024K.

          In simple terms, if your system has more than 512K, the actual
          starting address is equal to total system memory plus 384.

          Some examples:

              SYSTEM  STARTING
              MEMORY  ADDRESS
              ------  --------

            SW2-8 - Memory Parity Checking

            The above list of addresses is not complete.  After the 3072K
            address, we have listed the settings for every megabyte only.
            Switches 5,6 & 7 determine the addresses between.  If you are
            unable to interpolate the correct starting address from the above
            information, contact AST to order the complete documentation.


        NOTE: Linear memory installed previous to the Rampge would consist of
              Base memory (maximum 640K) plus extended memory (non-EMS)
              installed in the system before the Advantage is installed.  If
              the starting address is set below 640K, the Advantage will
              automatically "backfill" base memory up to 640K, with the
              remainder of linear memory going to extended memory.

              You will have to adjust your machines CMOS with your set-up
              program only if you add conventional or extended linear memory
              with the Advantage.  Do not change the set-up to reflect expanded
              EMS memory.

          "forced true". To force a signal true, remove the appropriate jumper
          above.

        The above list of addresses is not complete.  After the 3072K address,
        we have listed the settings for every megabyte only.  Switches 5,6 & 7
        determine the addresses between.  If you are unable to extrapolate the
        correct starting address from the above information, leave a question
        on the BBS.

        NOTE: The "STARTING ADDRESS" is not the same as "MEMORY INSTALLED IN
              SYSTEM".  Because of the reserved rom area residing between
              A0000h and 100000h, extended memory has a linear starting address
              of 1024K.

              In simple terms, if your system has more than 512K, the actual
              starting address is equal to total system memory plus 384.  Some
              examples:

              SYSTEM       STARTING
              MEMORY        ADDRESS

    Jumper positions E1 through E7 are three pin jumpers.  E1-E6 control the
    signals sent to the serial ports, and for the most part should remain in
    the default position (on pins 1 & 2 to the left).  In rare cases, you may
    want to force certain signals true, in which case the appropriate jumper
    would move to the right pair of pins (2 & 3).

        E1 - Move to 2 & 3 to force CTS true (Port One)
        E2 - Move to 2 & 3 to force DSR true (Port One)
        E3 - Move to 2 & 3 to force DCD true (Port One)

        E4 - Move to 2 & 3 to force CTS true (Second Port Option)
        E5 - Move to 2 & 3 to force DSR true (Second Port Option)
        E6 - Move to 2 & 3 to force DCD true (Second Port Option)

    Slot eight (closest to the power supply) in the IBM PC/AT is a
    non-standard slot.  If the I/O Mini II is installed in this slot,
    you must move the jumper at E7 to right pair of pins (2 & 3).

              640K.  SW7 & SW8 define the amount of conventional memory
              available to the PC from the Rampage board.  In some cases, the
              total of existing PC memory and Rampage conventional memory may
              add up to more than 640K.  In this situation, conventional memory
              stops at 640K and the balance becomes available as expanded
              memory.


JUMPER SETTINGS

    The only user-configurable jumpers on the Rampage are the three pin jumper
    labeled "E1-E2-E3" and the two pin jumper at "E8-E9".  By attaching E1-E2,
    Dual Page Mode is disabled, allowing only one set of mapping registers for
    expanded memory.  Attaching E2-E3 enables Dual Page Mode, allowing two
    mapping registers.  AST recommends two mapping registers, as they are
    useful for multitasking purposes.

    Attaching E8-E9 enables parity checking.  It is strongly recommended that
    parity checking is always enabled.

The Rampage AT is a memory expansion adapter for the IBM PC/AT and 100%
compatibles running at *6MHz.  Memory can be expanded on this board from 512K
to 2048K using industry standard 256K dynamic RAM chips with a minimum speed
requirement of 120NS.  Memory standards supported by the Rampage AT include
conventional (base 640K), linear extended, LIM 3.2, LIM 4.0, and EEMS.

    * Later versions of the Rampage AT are rated for 8MHz operation.
      The part number on the solder (non-component) side of the board
      determines which revision you have.  If the part number is
      202079-302C or 202079-302D, the Rampage is rated for 8MHz
      operation. Any other revision is rated for 6MHz only.

        Switches 5,6 & 7 determine the addresses between.  If you are
        unable to extrapolate the correct starting address from the above
        information, contact AST to order the complete documentation.

        NOTE: Linear memory installed previous to the Rampge would consist of
              Base memory (maximum 640K) plus extended memory (non-EMS)
              installed in the system before the Rampage is installed.  If the
              starting address is set below 640K, the Rampage will
              automatically "backfill" base memory up to 640K, with the
              remainder of linear memory going to extended memory.

              You will have to adjust your machines CMOS with your set-up
              program only if you add conventional or extended linear memory
              with the Rampage AT.  Do not change the set-up to reflect
              expanded EMS memory.

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

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.

RampagePlus 286                                     AST Part Number 202349-001

The AST RampagePlus 286 board offers flexible and powerful memory enhancement
for the AST Bravo/286, AST Premium/286, AST Premium Workstation, IBM PC/AT,
IBM PS/2 Model 30 286,and compatible computers.  It offers complete hardware
compatibility with Expanded Memory Specification (EMS) 4.0 software.

The RampagePlus 286 Smart Switch configuration software eliminates the need to
set board switches.  The software can make optimal settings for your computer
automatically, or you can select from easy to use menus. The RampagePlus 286
board retains your selected configuration even when your system is turned off.

You can upgrade your RampagePlus 286 board's memory to a maximum of eight
megabytes (MB) with single inline memory modules (SIMMS) that snap in and out
of the board sockets.  The optional I/O Pak 286-SP Piggyback board (AST P/N
500560-002) adds one serial port and one parallel port to your RampagePlus 286
board.  The RampagePlus 286 board has four pairs of sockets called banks.
Rampage Plus 286 can use 256K or 1MB SIMMs in combinations up to 8MB.  DO NOT
MIX SIMM SIZES AND SPEEDS WITHIN A BANK THIS WILL CAUSE ERRORS.


CHANGING THE DEFAULT JUMPER

To use automatic mode after adding or removing memory, you must set the
default configuration jumper (J3) to the alternate position. This disables the
memory on the board until you reconfigure it with the SmartSwitch (RAMP.COM)
program.  For example, if the jumper is on pins 1 and 2, move it to pins 2 and
3, if the jumper is on pins 2 and 3, move it to pins 1 and 2.

    SW1-5 - Emulation Switch

        By turning on the emulation option (SW1-5), the 3G Plus II will
        emulate CGA graphics on an EGA monitor.  This is useful for cases when
        your software does not support Enhanced Graphics.  If you have a
        monochrome monitor, turning SW1-5 on will allow the 3G Plus II to
        emulate Hercules graphics.  The emulation mode can be used with the 3G
        Plus II in the primary or secondary position.

    SW1-6 - Auto Configuration

        Turning SW1-6 to the "on" position enables the auto configuration
        mode.  This allows the 3G Plus II to detect the type of monitor it is

AST VGA                                             AST Part Number 202249-001

The AST VGA is a Video Graphics Array video adapter for use with the IBM PC,
PC/XT, PC/AT, and 100% compatible machines.  It comes standard with 256K of
video memory and a 15-pin connector for sending analog video signals to a
PS/2, VGA, or Multisynch monitor.  Video modes supported by the AST VGA are
MDA, HGC, CGA, EGA, and VGA, all on analog monitors.


JUMPER SETTINGS

    The AST VGA has only one user-configurable jumper setting; a three pin
    jumper that must be connected on the left or right pair of pins depending
    on the kind of monitor connected to the adapter.

    The left pair (1 & 2) of pins should be connected if the monitor is a PS/2
    or other analog only VGA monitor.

    The right pair (2 & 3) of pins should be connected if the monitor is a
    Multisynch monitor.  Note that the Multisynch must be set for analog
    operation.  Most Multisynch monitors come with a standard 9-pin TTL cable.
    If this is the case, a 9-pin to 15-pin adapter cable must be obtained from
    the manufacturer of the monitor.

HotShot/286                                         AST Part Number 202160-001 **

HotShot/286 is an accelerator card designed to fit any expansion slot in your
IBM personal computer PC or PC XT or compatible computer.

HotShot/286 features:

   o A 16-bit Intel 80286 microprocessor that runs at a clock speed of 10
     megahertz (MHZ)

   o Cache memory

Using Cache:

    HotShot/286 speeds your PC's access to the most-recently accessed data and
    instructions. Words can be accessed up to twice as fast from cache memory.
    Switch-selectable cached memory also allows HotShot/286 to avoid areas of
    memory that cannot be cached (for example, the memory range used by the
    PC-XT fixed disk controller).

Using a Co-Processor:

    HotShot/286 accommodates the Intel 80287 math co-processor.  With the
    appropriate software, the math coprocessor enables your PC to perform
    high-speed, highly accurate arithmetic, logarithmic, and trigonometric
    functions in parallel with the processor.

EEMS Compatibility:

    HotShot/286 is designed to complement and accelerate operation with AST's
    enhanced expanded memory specification (EEMS) products such as Rampage or
    SixPakPremium.  HotShot/286 automatically updates cache memory whenever
    your AST EEMS product swaps memory pages, providing designed-in
    compatibility.
