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.

information, contact AST to order the complete documentation.

NOTE: The "STARTING ADDRESS" is not the same as "MEMORY INSTALLED

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.

Rampage! AST Part Number 202073-001

The Rampage is a memory enhancement board designed for use with the IBM PC,
XT, and 100% compatibles running at a speed of 4.77MHz. The Rampage can be
populated from 256K to 2048K using industry standard 256K DRAM chips of at
least 150ns speed. The memory standards supported by the Rampage include
conventional (640K base), LIM 3.2, EEMS, and LIM 4.0. Extended memory can be
emulated by using the REX.SYS device driver. In order to access any
non-coventional memory, the REMM.SYS device driver must be used.

NOTE: The maximum amount of conventional memory in an IBM PC/XT is
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.

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)

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.

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.

**** AST HOTSHOT/286 ****

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.
