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.
AMDEK 286 8MHZ
Reports of compatibility with Above Boards and Matched Memory Classic.
Intel has done limited testing with the Amdek 286 8MHz and no
compatibility issues were found.
AMI 286 12MHZ
*CUSTOMER REPORT* of compatibility with current Above Boards and Matched
Memory Classic. System bus speed is 12MHz. Probably not compatible with
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.
AT&T
AT&T 6286
*CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
Memory Classic.
Tech Notes: This is a 12MHz 80286-based system with 1Mb on the system
board. Make sure SETBOARD configures the Above Board or Matched Memory
Classic board for 12MHz bus operation. Probably not compatible with the
discontinued Above Board AT and PS/AT due to the fast bus speed.
We have mixed reports about configuring an Above Board or Matched Memory
Classic board as extended memory in this system. In some cases it was
necessary to set the extended memory starting address at 1024K in
SETBOARD. In other cases a starting address of 1280K worked. In most
cases, a starting address of 1408K will work fine.
AT&T 6286 WGS
*CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
Memory Classic.
Tech Notes: This is a 12MHz 80286-based system with 1Mb on the system
board. Make sure SETBOARD configures the Above Board or the Matched

cases, a starting address of 1408K will work fine.
AT&T 6300 PLUS
Above Boards and Matched Memory Classic are INCOMPATIBLE with this system.
This is an 80286-based system but there are no AT 16-bit bus slots. The
AT&T 6300 Plus does have some 8-bit bus slots but they are not IBM
compatible.
AT&T 6310
Compatible with current Above Boards and Matched Memory classic. The AT&T
Technical Lab claims compatibility with the discontinued Above Board 286,
PS/286, AT, & PS/AT also.
This 80286-based system has an 8Mhz, 1 wait state data bus. Uses Phoenix
BIOS, 230W power supply, has programmable diagnostics. Comes with 512K on
the motherboard and is expandable to 1Mb.
AT&T 6312
*CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
Memory Classic in this 80286-based computer. AT&T has approved the Above
Board Plus.
Tech Notes: Specify a 12MHz bus and 150ns chip speed in SETBOARD. This
12MHz 80286-based system comes with a 1Mb system board configured as 640K
base & 384K extended. Probably not compatible with the discontinued Above
Board AT and PS/AT due to the fast bus speed.
BENTLEY 286
*CUSTOMER REPORTS* of compatibility with Above Boards and Matched Memory
Classic in this 80286-based computer.
Tech Notes: This computer has 1Mb on the system board that can be
configured as 640K conv, 384K extended or 512K conv, 512K extended. The
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 the discontinued Above Board 286, PS/286, AT, and PS/AT.
COMPAQ DESKPRO 286 (12MHZ)
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
Compatible with current Above Boards and Matched Memory Classic in the 16-
bit slot of this 80286-based computer. Also compatible with Above Board
AT & PS/AT in the 16-bit slot.
This computer has only one 16-bit slot and an 8-bit slot. Above Boards
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.
System specs:
CPU 80286 10MHz (Soldered).
RAM 640K conventional, (also 256/512), 384K expanded built in.
MCP 287XL or 287-8 socket
Rsv Mem Video ROM at C000-C5FFF. The drive controller (on the
motherboard) uses no reserved memory in the C000-DFFF
range...built into system ROM.

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

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.
