10 MHZ 286 CLONES & ABOVE BOARD 286/PLUS

  Some 10MHz 80286-based computers display intermittent Parity Check 2 or
  EMM errors at power-up.  If this happens, run the SETBOARD program from
  the Intel Memory Board installation disk and specify a 6-8MHz bus.

ACER
ACER 286

  *CUSTOMER REPORT* of compatibility with Above Boards and Matched Memory
  Classic.

  There is a jumper which indicates the amount of memory on the system
  board. If this is not set correctly you will get memory size errors when
  the computer powers up.

ACER 900

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic.

  The ACER 900 is a 10MHz 80286-based system.  You will need to choose the
  10MHz bus speed option in the SETBOARD program.  Probably not compatible
  with the discontinued Above Board AT and PS/AT due to the fast bus speed.

ACER 910

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic.

  Customer reported that this system is an 80286-based system running at
  10MHz, but SETBOARD needs to be set for a 6-8MHz bus system.

ALR
ALR DART

  *CUSTOMER REPORTS* of LIMITED COMPATIBILITY with current Above Boards and
  Matched Memory Classic.  A customer reported that an Above Board does not
  operate correctly with the system running at 10MHz.  The Above Board
  worked fine with the system running at 8MHz.  Probably not compatible with
  the discontinued Above Board AT and PS/AT when this computer is running at
  the 10MHz bus speed.

  Tech Notes: Dart has 2Mb on the system board that can be configured two
  different ways according to the position of SW2 on the motherboard switch
  block:

  1.   Mode 1 (SW2-ON) :  system memory is 640K conv.+ 1408K ext.
  2.   Mode 2 (SW2-OFF):  system memory is 512K conv.+ 1536K ext.
       In Mode 2, an Above Board or Matched Memory Classic can be used to
       provide conventional memory to 640K.

ALR POWERFLEX

  *MIXED CUSTOMER REPORTS* of compatibility with current Above Boards  and
  Matched Memory Classic.  This is an 80286-based computer that may have an
  80386SX upgrade board which fits into a proprietary slot.

  Tech Notes:  According to some customers, ALR's manual states that the
  BIOS Expanded Memory Manager should be disabled before installing an Above
  Board.  SETBOARD may give error messages like "incorrect bus type" if this
  is not done. Disabling the ALR BIOS Expanded Memory Manager has allowed
  some customers to get Above Boards working in these systems.

  Other customers have reported a "Purple Scrambled" screen when the
  computer is cold booted, but sometimes works on a warm boot when an Above
  Board or Matched Memory Classic is installed.

  An ALR representative has stated, "a CONDITIONAL compatibility exists with
  our Powerflex line and Intel's Above Boards."  and would not go into what
  the conditions were. ALR recommends customers use the proprietary ALR
  memory cards.

  the Above Board AT or PS/AT due to the faster bus speed.

AMSTRAD 286

  *CUSTOMER REPORTS*  of LIMITED COMPATIBILITY with current Above Boards and
  Matched Memory Classic.  This is a 12MHz 80286-based system.  The Above
  Board Plus, Plus 8, and Matched Memory Classic are INCOMPATIBLE as
  expanded memory but work as extended memory.  The incompatibility is with
  memory boards that support an expanded memory page frame larger than 64K.
  The Above Board 286 is compatible.  Probably not compatible with the Above
  Board AT or PS/AT due to the faster bus speed.

AMERICAN AT

  *CUSTOMER REPORTS* of compatibility with Above Boards and Matched Memory
  Classic.  The American AT is an 80286-based system.  Customers report
  compatibility with the Above Board AT and PS/AT also.

ARCHE RIVAL 12MHZ

  *CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
  Memory Classic in this 80286-based system.  Probably not compatible with
  the discontinued Above Board AT and PS/AT due to the 12MHz bus speed of
  this computer.

  This system has sockets for up to 1Mb on the system board which must be
  filled before using an Above Board or Matched Memory Classic to provide
  extended memory.

AST
AST PREMIUM 286

  *CUSTOMER REPORTS* of compatibility with current Above Boards and the
  Matched Memory Classic Boards in this 80286-based system.  You will need
  to choose the 10MHz bus speed option in the SETBOARD program.  Be sure the
  "zero wait state mode" on the AST system board is disabled.  Probably not
  compatible with the discontinued Above Board AT and PS/AT due to the fast
  10MHz bus speed.

  See also AST FastRAM which is a board that adds conventional memory and
  may conflict with SOFTSET.

  One user reported that an Above Board AT worked as extended memory if the
  "zero wait state" mode was disabled.  This system also takes the Intel
  80287-8.

  One customer reported that the way to set the wait states is to change
  jumper E2 on the AST FASTRAM Memory Card:

      Jumper on E2 sets 0 wait states
      Jumper off of E2 sets 1 Wait State

  The customer read it directly from the AST manual.  It was the only
  reference to wait states he could find in the manual. Changing the jumper
  fixed the problem in this case.  An Above Board wasn't seen on POST with
  E2 on.  Customer removed E2 and the Above Board counted on POST.

AST 123X WORKSTATION

  *CUSTOMER REPORTS* of compatibility with Current Above Boards and the
  Matched Memory Classic in this 80286-based system as expanded memory.
  Intel has not received any reports one way or the other about extended
  memory compatibility issues.

  Tech Notes:  It was reported that SOFTSET gave the error "incompatible
  board..." in this computer.  If this happens, it will be necessary to
  manually install the EMM.SYS device driver for expanded memory.  SETBOARD
  showed that I/O addresses 218 & 258 were being used besides the I/O
  address the Above Board occupied.  This system has only two expansion
  slots, built in VGA video support, and comes without a FastRAM board
  installed.

AT JET

  *CUSTOMER REPORT* of compatibility with current Above Boards and Matched
  Memory Classic in this 80286-based computer.  This system apparently has a
  12MHz data bus.  An odd symptom of this computer is that TESTAB would lock
  up when the Above Board was set for a 6/8MHz bus.  Probably not compatible
  with the discontinued Above Board AT and PS/AT due to the 12MHz data bus
  of this computer.

  system speed is 6-10MHz selectable.

CITIZEN 286

  *CUSTOMER REPORT* of INCOMPATIBILITY with Above Boards and Matched Memory
  Classic.  Report indicated that this system runs at 12.5MHz, 0 wait
  states.  A system running at 0 wait states violates the IBM specification
  of 1 wait state and is not fully IBM compatible.  Intel classic bus memory
  boards require the IBM standard of 1 wait state.

COMMODORE PC 40 III

  *CUSTOMER REPORT* of LIMITED COMPATIBILITY with Above Boards and Matched
  Memory Classic.

  Commodore mentions the Intel Above Board Plus for memory expansion in the
  owner's manual for this machine.

  This is a 6/8/12MHz selectable system.  It is necessary to set the system
  speed to 8MHz when using an Above Board or Matched Memory Classic in this
  computer.  When this system is running at 12MHz, the data bus runs at 0
  wait states and an Above Board or Matched Memory Classic board will not
  function properly.  A system running at 0 wait states violates the IBM
  specification of 1 wait state and is not fully IBM compatible.  Intel
  Above Boards require the IBM standard of 1 wait state.

COMPAQ
COMPAQ DESKPRO 286

  Compatible with current Above Boards and Matched Memory classic.  Also

  Compatible with current Above Boards and Matched Memory Classic.  Also
  compatible with the discontinued Above Board 286, PS/286, AT, and PS/AT.

  This 80286-based system has 8 rows of sockets on the motherboard that will
  accept either 64K DRAMS or 256K DRAMS (120ns).  There is also 128K of
  memory soldered onto the system board.

  Maintains a standard 8MHz bus.  Uses an Intel 80287-8 math coprocessor.

PARITY CHECK 2 ERROR IN DESKPRO 286 12 MHZ

  If you get this message after installing an Above Board or Matched Memory
  Classic, it is likely you have overlapping conventional memory, (both the
  Above Board or Matched Memory Classic, and the Compaq motherboard are
  trying to supply conventional memory).

  There are two ways to correct this problem:

  1.   The first is to temporarily disable the Compaq motherboard memory
       down to 256K or 512K. (If the error is Parity Check 2 40000,
       disable motherboard memory down to 256K, if the error is Parity
       Check 2 80000, then disable motherboard memory down to 512K).
       There are three steps to this procedure:

       a.   The Compaq motherboard switch block is located on the front
            left corner of motherboard.

       SWITCHES   2      3     MEMORY SIZE
                 ON     ON     Disable RAM and ROM
                 ON     OFF    Limit motherboard to 256K
                 OFF    ON     Limit motherboard to 512K
                 OFF    OFF    Enable all base memory, 640K max

       b.   Rerun SETBOARD.  Tell the Above Board or Matched Memory
            Classic to supply NO conventional memory.
       c.   Set Compaq motherboard switches back to 640K.

  2.   The second method of eliminating this problem is to find a way to
       rerun SETBOARD without first correcting the conventional memory
       overlap. There are four steps to this approach:

       a.   Temporarily remove the Above Board or Matched Memory Classic
            from the system.
       b.   Copy the SETBOARD.EXE program from the Above Board / Matched
            Memory Classic installation diskette to the hard disk.
       c.   Reinstall the board.
       d.   Rerun SETBOARD from the hard disk and set the Above Board or
            Matched Memory Classic to supply NO conventional memory.

  NOTE:     Overlapping conventional memory causes Parity Check 2 errors
            during floppy disk accesses.  If the Above Board or Matched
            Memory Classic is removed while SETBOARD is being copied to
            the hard disk, there will not be a Parity Check 2 error. When
            the Board is reinstalled and SETBOARD is run from the hard
            disk, SETBOARD should be able to successfully reprogram our
            board without a parity error occurring.  People who do not
            feel comfortable changing motherboard switches should use
            this approach.

EXTENDED MEMORY IN DESKPRO 286 (12MHZ)

  If you use an Above Board or Matched Memory Classic to supply extended
  memory, you have two options. They are:

  1.   Fill TWO rows on the motherboard with 256K chips for a total of
       640K conventional memory, (128K on the motherboard is not readily
       visible, but is there none the less).  You should have SIX rows of
       empty sockets on the motherboard.

       Switches 4 and 5 on SW1, (near the front left corner of the
       motherboard),  should both be ON.  This says that the motherboard
       WILL NOT supply ANY extended memory.

       Start the Above Board or Matched Memory Classic extended memory at
       1024K, (1.0M), in SETBOARD.

  2.   Fill all EIGHT rows on the motherboard with 256K chips for a total
       of 640K of conventional memory and 1536K of extended memory on the
       motherboard.

       Switches 4 and 5 on SW1 should both be OFF.  This says the
       motherboard will supply extended memory from 1Mb to 2.5Mb.  Start
       the Above Board or Matched Memory Classic extended memory at
       2560K, (2.5M) in SETBOARD.

  Any combination BETWEEN these two configurations is not allowed, and the
  Deskpro will not "see" our board.

COMPAQ PORTABLE 286

  Compatible with current Above Boards and Matched Memory Classic.  Also
  compatible with the discontinued Above Board 286, PS/286, AT and PS/AT.

COMPAQ PORTABLE II

  and Matched Memory Classic can only be used in 8-bit slots if the
  computer's processer is an 8088 or an 8086.

  System may have optional extended memory on a board under the motherboard.

COMPAQ PORTABLE III

  Compatible with current Above Boards and Matched Memory Classic.  The
  Above Board AT and PS/AT are NOT reliable in this 80286-based system.

  An expansion chassis is required for any add-in boards.  Inserting a board
  into an expansion chassis must be done with care to avoid damage to the
  board,  it's a bit tricky to get it installed just right.  Standard ports
  are defaulted to LPT1 and COM1.

  This system requires an Intel 80287-8.

COMPAQ 286N

  Compatible with current Above Boards and Matched Memory Classic.
  It is necessary to disable Compaq's CEMMP if installing an Above Board or
  Matched Memory Classic as expanded memory.  If installing an Above Board
  or Matched Memory Classic as extended memory, choose an extended memory
  starting address of 1024K, (1.0M) in SETBOARD.
  This system uses the Intel 287XL or 80287-8.  There is only ONE switch,
  switch 5 on a block of 6, that is used to toggle between 8 and 12 MHz math
  coprocessors.

  Introduction

  Benchmarks are intended to give a standard measure of performance that can
  be used to predict how well application code will execute.  These
  benchmark programs should be representative of the intended applications.
  However, the performance measured is often the combined characteristic of
  a given computer architecture and many other tightly-coupled system
  software and hardware constituents.  The memory and I/O subsystem design,
  as well as the operating system and the software development tools, may
  dominate the results and make the comparison difficult.

  This document contains performance measurements in both DOS and UNIX
  operating environment, which can be used as predictors of real application
  performance.

  The Intel RapidCAD Engineering CoProcessor

  The Intel RapidCAD Engineering CoProcessor, the newest member of Intel386
  product family, is the highest performance floating-point upgrade for
  Intel386 DX microprocessor-based systems.  Manufactured using high speed
  CHMOS V technology, the Intel RapidCAD Engineering CoProcessor is a two
  chip set: RapidCAD-1 and RapidCAD-2.  The first chip, RapidCAD-1, replaces
  the Intel386 DX microprocessor.  It is pin compatible with the Intel386DX
  microprocessor and integrates the central processing unit (CPU) and
  floating point unit (FPU) on the same silicon die reducing the inter-chip
  communication delays.  Eliminating the communication overhead of
  transferring commands, data and results over the I/O bus between the CPU
  and the math coprocessor (MCP), enables exceptional floating-point
  performance.  The second chip, RapidCAD-2, is installed in the Intel387 DX
  Math CoProcessor socket.  It provides hardware compatibility with the
  unmasked floating-point exception reporting in standard Intel386
  microprocessor-based architectures.  The floating-point and binary coded
  decimal data formats fully conform to the ANSI/IEEE Standard 754-1985 for
  binary floating-point arithmetic.  The Intel RapidCAD Engineering
  CoProcessor is binary compatible with the Intel386DX microprocessor and
  the Intel387 DX, Intel387SX, Intel287XL and 8087 Math CoProcessors.

  Intel RapidCAD Engineering CoProcessor Performance Summary

  Benchmark results confirm that the RapidCAD Engineering CoProcessor runs
  floating-point code from 56 to 146 percent faster than the Intel386 DX
  microprocessor with the Intel 387DX math CoProcessor.  This exceptional
  floating-point performance translates into excellent performance
  improvement for applications which makes extensive use of the floating-
  point instruction set.  Application benchmarks show performance
  improvement averaging 30 to 40 percent, and as high as 67 percent for 3D
  Studio and MathCAD. The Intel RapidCAD Engineering CoProcessor's
  exceptional floating-point performance translates into real time savings
  for the engineering professional using an Intel386 DX microprocessor-based
  system running CAD or scientific application software.

  Benchmark Tests:
  Standard benchmark tests were used to separately evaluate integer and
  floating-point performance.  DOS and UNIX standard benchmark tests were
  run.  All applications tested run under DOS or Windows.  Application
  performance was estimated using two kinds of tests.  A subset of the BYTE
  Application Benchmark Version 2.0 and the AutoCAD Benchmark Test Series
  Distributed by the AutoCAD Users Group of San Diego Version 1.1, were used
  as part of the application benchmark testing.  They run automatically,
  using the system clock to measure the execution time.  For applications
  where an automatically running test was not available, such as AutoShade
  and 3D Studio, typical commands which use RapidCAD's floating-point
  capability were run and the execution time was measured with a stop watch.

  For each test there are two sets of results, one obtained with the
  Intel386 DX microprocessor and Intel387 DX Math CoProcessor, the other
  with Intel RapidCAD Engineering CoProcessor.  A performance index is
  calculated in each case showing the relative execution speed delta using
  the Intel RapidCAD Engineering CoProcessor vs. the Intel 386 DX
  microprocessor and the Intel387 DX Math CoProcessor.

  DOS Standard Benchmark Tests

  Dhrystone is an industry-standard benchmark test designed to measure
  system programming performance.  It includes weighted percentages of
  procedure calls, loops, integer assignments, integer arithmetic and
  logical operations.  The result is CPU speed expressed in Dhrystones/sec.
  Sixteen-bit Dhrystone Version 2.0 and a 32-bit Dhrystones Version 2.1 were
  used.

  Whetstone is an industry-standard benchmark test designed to predict
  performance in a floating-point intensive enviroment.  It is a synthetic
  mix of floating-point and integer arithmetic, transcendental functions,
  floating-point array computations, and floating-point subroutine calls,
  based on statistical analysis of scientific FORTRAN programs.  The result
  is expressed in KIPS (kilo instructions per second).  Single and double
  precision 16- and 32-bit Whetstones were used.  In addition the Microway
  Whetstone benchmark was run to give a more comprehensive measure of
  floating-point performance in 32-bit protected mode.

  UNIX Standard Benchmark Test

  The SPEC benchmark Suite Release 1.0 consists of 10 FORTRAN and C
  benchmarks that are intended to be meaningful samples of applications
  which perform fixed- and floating-point logical and arithmetic operations
  as well as disk I/O in a technical environment.  Many of these benchmarks
  have been derived from publicly available application programs.

  The benchmark suite may be divided in two separate benchmark suites to
  distinguish between the integer and floating-point performance.  This
  allows for better performance prediction under different operating
  environments.  The integer performance represents a more appropriate
  instruction mix for commercial applications in a business environment.
  The floating-point performance can be used to predict the system
  performance in a technical environment for scientific and engineering
  applications.  The global SPEC index, SPECmark, is the geometric mean of
  all test results.  The SPEC integer index, SPECint, represents the
  geometric mean of the results for the four C programs.  The SPEC floating-
  point index, SPECfp, represents the geometric mean of the results of the
  six FORTRAN programs.

  DOS Application Benchmark Tests

  Generic 3D Drafting Version 1.1
  The model BEARING.3DD was used to execute a perspective change (VIEW,
  Perspect VP) with the coordinates 0,0,-25 and 350,400,400.  The elapsed
  time was measured with a stop watch.

  AutoCAD Release 11
  The BYTE Application Benchmark Version 2.0 test and the Benchmark Test
  Series Distributed by The AutoCAD Users Group of San Diego were used.
  This series of tests execute a typical mix of commands that might be
  issued by an AutoCAD user.  These tests measure the elapsed time using the
  system clock.

  A simple model was created (FLANGE.DWG) to test solids subtract, mesh and
  filled shade.  The elapsed time was measured with a stop watch.

  AutoShade with RenderMan Release 2.0
  The sample film KITCHEN.FLM was used to test full shade and RenderMan
  render.  The elapsed time was measured with a stop watch.

  3D Studio Release 1.0
  The sample models CITY.3DS, RACECAR.3DS, and STILLIFE.3DS were used to
  test the render function, with the following setting: Shading limit =
  Phone; Anti-Alias= High; Shadows = On; Mapping = On; Hidden Geometry =
  Hide; Render Output = Display.  The elapsed time was measured with a stop
  watch.

  Cadkey 386 Version 4
  To measure performance with the standard drawing functions an array of
  1000 ellipses was first drawn and then deleted.  To test the performance
  of advanced solid functions the sample model SOLID4.PRT was used.  A
  complex process performning solid boolean operations (solid subtraction
  and plane sectioning), mass properties and a smooth shading followed by
  the rendering (with Shading = Phong) of the resulting image were
  performed.  The elapsed time was measured with a stop watch.

  MicroStation PC Version 4.0
  The sample ORBITER.DGN model was used for hidden lines removal, smooth
  shading, phong shading, stereoscopic rendering and a zoom out.  The
  elapsed time was measured with a stop watch.

  Upfront Version 1.0
  The sample drawing LIBRARY.UPF was used and two view change tests were
  done: from initial view to Birdseye and back.  The elapsed time was
  measured with a stop watch.

  Mathematica 2.0 for DOS 386/7 and Mathematica 2.0 for Windows
  The execution time of Plot3D[10 sin[x+Sin[y]], {x, -10, 10}, {y, -10, 10},
  PlotPoints -> 80] was measured with a stop watch.

  MathCAD 2.50
  The BYTE Application Benchmark Version 2.0 test was used.  It calculates a
  convolution integral and evaluates an iterative function system.  This
  test measures the elapsed time using the system clock.

  PC-Matlab Ver 3.5g
  The BYTE Application Benchmark Ver 2.0 test was used.  This test performs
  a mix of matrix and signal processing operations.  This test measures the
  elapsed time using the system clock.

  SPSS/PC + V4.0.1
  A statistics example with 1473 cases was used for descriptive statistics
  (means) and a graphic representation with Harvard Graphics.  The elapsed
  time was measured with a stop watch.

  STATGRAPHICS Ver 4.0
  Three randomly gneerated 1000 samples series were used for summary
  statistics (STATS) and multiple regression.  The elapsed time was measured
  with a stop watch.

  Lotus 1-2-3 Release 3
  The BYTE Application Benchmark Ver 2.0 test was used.  The test loads and
  recalculates a spreadsheet based on the Savage formula, then it runs a
  macro that performs a binary goal seek.  Additionally, a large block of
  text data is loaded, copied and then saved.  This test measures the
  elapsed time using the system clock.

  Excel Version 3.0
  The BYTE Application Benchmark Ver 2.0 test was used.  The test is similar
  to the one for Lotus 1-2-3.  It loads and recalculates a spreadsheet based
  on the Savage formula, then it runs a macro that performs a binary goal
  seek.  This test measures the elapsed time using the system clock.

  Note:  The loosely copuled internal architecture makes RapidCAD more
  sensitive to wait states than Intel386 DX CPU.  Therefore in systems
  without cache and more than three wait states for memory accesses, the
  integer performance of RapidCAD becomes lower than the integer performance
  of Intel386 DX Microprocessor.  However this is not likely to occur, since
  almost all Intel386 DX microprocessor-based PCs have cache in their
  configuration.

  Additional wait states in the MCP I/O cycles may considerably increase
  RapidCAD's floating-point performance relative to Intel386 DX
  microprocessor and Intel387 DX Math CoProcessor.
