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.

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.

Intel RapidCAD Performance Brief Intel RapidCAD Engineering CoProcessor Performance Brief Table of Contents Introduction 1 The Intel RapidCAD Engineering CoProcessor 1 Intel RapidCAD Engineering CoProcessor Performance Summary 2 Test Configurations 2 Benchmark Tests 2 DOS Standard Benchmark Tests 3 UNIX Standard Benchmark Test 3 DOS Application Benchmark Tests 4 Table 1- DOS Application Benchmark Results 7 Table 2- DOS Standard Benchmark Results 10 Table 3- UNIX Benchmark Results 11 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. Test Configurations The DOS tests were performed on a COMPAQ DeskPro 386/33MHz. Memory 640KB base and 7MB extended Video COMPAQ mother board VGA Disk 80MB IDE Operating Compaq Personal Computer DOS 3.31 System Windows 3.0 The UNIX tests were performed on a COMPAQ SystemPro 386/33MHz Memory 640KB base and 7MB extended Video COMPAQ mother board VGA Disk COMPAQ Disk Array Operating System AT&T UNIX System V/386 Release 4.0 Version 2.0 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. AutoCAD Release 11 Advanced Modelling Extension (AME) 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.

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.
