Assemble your toois.
The only tools required are a screwdriver to remove the cover on your computer and possibly a pin-straightening device or needle-nosed pliers. If you will be replacing a currently installed coprocessor with the CX-83D87. you will also need a PGA extractor tool.

നിങ്ങളുടെ കമ്പ്യൂട്ടർ, as well as the CX-83D87, may be damaged by static discharge. It is very important to ground yourself by touching the metal back or side panel on your computer. An illustration of this is seen in Figure l. You can remain grounded during the installation by using a ground strap. If you are not using a ground strap, care should be taken to avoid moving around during installation. Shuffling your feet, especially on carpet, will generate static electricity. Each time you move, discharge yourself by touching the bare metal back or side panel on your computer.

• Turn off the power switch on your computer and unplug the power cord from the wall outlet. Disconnect all cords and cables from your computer. Remove the cover from your computer. Instructions for removing the cover can be found in your computer’s manual.
• In some computers, switches must be set or jumpers must be installed to ensure proper recognition of the coprocessor. Switch settings and locations can be found in your computer’s manual. Some computers also contain this information on the metal plate covering the disk drives. If you are replacing an Intel 80387 with the CX-83D87 the switches or jumpers will already be in the proper configuration. If you are installing a coprocessor in this computer for the first time, set any switches or install jumpers as required.

1. Locate the coprocessor socket in your computer. It should be a large square socket on your computer’s system board. If you do not currently have a coprocessor installed, it will be empty. If you are replacing an existing coprocessor, that coprocessor will be seated in the coprocessor socket. Diagrams of the socket location can be found in your computer’s manual. Some computers also contain a diagram on the metal plate covering the disk drives. Some computers will contain two empty square sockets: one for a Weitek coprocessor and one for an Intel 80387 compatible coprocessor. The CX-83D87 fits into the socket for the Intel 80387 compatible coprocessor. This socket is smaller then the Weitek socket.
2. In some computers, the coprocessor socket is not readily available and circuit boards and/or cables must be removed to gain access to this socket. Discharge yourself from static electricity before removing any boards or cables. Remember how to replace these boards and cables and put them in a safe place while completing the installation of the coprocessor.
3. If you are replacing an existing coprocessor, you must first remove it from the socket. A PGA extractor tool is recommended for removing the existing coprocessor. Lift the device out carefully to avoid bending any pins. It can perhaps be used in a computer that does not require the enhanced performance of the CX-83D87.
4. Remove the CX-83D87 from the anti-static tube and check for bent pins. Carefully straighten any bent pins using a pin-straightening device or needle-nose pliers.
5. Place the CX-83D87 in the socket in the correct orientation. See Figures 2 and 3. If there is a bevel in the line around the socket, the beveled corner on the package should be placed over the bevel. Otherwise, the notch in the socket should be aligned with the gold tab on the top of the package. NOTE: Sockets are sometimes installed incorrectly in a computer system so if there is a line drawn around the socket printed on the circuit board, alion the packaoe bevel to the drawn bevel instead of alionino to the notch on the  If the socket is intended for either a Weitek device or an Intel 80387 compatible device, the socket will be larger than the CX-83D87. Center the CX-83D87 in the socket. One row of pins should be visible on all sides.
   If in doubt as to the placement of the CX-83D87, refer to your computer’s manual for for further details. Remember the CX-83D87 should be installed in exactly the same manner as the Intel 80387. If you are still unsure, call the customer support number at Cyrix listed in Chapter 5 or contact your dealer for installation. 
6. Examine package from all sides to be sure all pins are going in correctly. If there are any bent pins, remove the CX-83D87 and straighten the pins before going on.
7. Press firmly and evenly with your thumb on the center of the package. Even when the component is fully inserted, the package will not be flush with the sockeJ”. The pins will be barely visible.

1. Replace any circuit boards and/or cables that were removed in order to gain access to the coprocessor socket.
2. Replace the cover and reconnect all cables and cords to your computer. Plug the power cord into the wall outlet.
3. നിങ്ങളുടെ കമ്പ്യൂട്ടർ ഓണാക്കുക.
4. Most computers require that a setup or configuration program be run to ensure recognition of the coprocessor. Your computer’s manual should tell you if this is required. If required, run the setup or configuration program as
5. directed in your computer’s manual.
6. If you are having problems with your computer, turn to CHAPTER 5 for troubleshooting advice.

FasMath Demonstration Disk
Cyrix has included a 5 inch Demonstration Disk to allow you to verify operation and provide a visual demonstration of the power of your new FasMath coprocessor.
To test the operation of your FasMath processor, turn on the computer and boot the DOS operating system. Insert the Demonstration Disk into the computer’s floppy disk drive. Direct the computer to use the floppy disk drive as its default drive by typing “A:” or “B:” and then pressing the ENTER key. Now type “FASMATH” and press the ENTER key,(1)
The program on the FasMath Demonstration Disk will test for the presence of the CX-83D87 and test for correct operation,c2, A status screen will be displayed informing you that correct operation was observed. If you fail to see the status screen or the status reports incorrect operation, then immediately turn off your computer and refer to CHAPTER 5 on Troubleshooting.
After verifying correct operation of your FasMath coprocessor you may now run the Demo programs which display the features of the CX-83D87. You may run the Demo programs from the floppy disk just by following the instructions on the status screen menu. However, to see the true performance of the FasMath coprocessor we recommend you copy the Demo programs on to your hard disk or ram disk before running them. Instructions for doing this are included on the Demonstration Disk in the file called “Read Me.”

കുറിപ്പുകൾ

1. Some computer systems slow the clock frequency down when running programs from a floppy disk. If the status window of the FasMath demonstration software shows a clock frequency slower than the system is capable of running, Cyrix recommends you copy the demonstration software to your hard-disk.
2. The visual demonstration software is designed to run on standard EGA or
   VGA systems. in the event your system will not run this program, the section of software designed to perform the operation verification can always be run by following these steps:
   1. From a DOS prompt, select the drive which contains the FasMath demonstration software by typing the appropriate drive letter followed by a colon, then press the ENTER key.
   2. Type each of the following lines and press enter:
      CHECKS -N-A FIO.TST
      CHECKS -N-A FARITH.TST
      CHECKS -N-A FTRAN.TST
      CHECKS -N-A FOS.TST
      (Some demonstration disks may contain a batch file called TEST.BAT which will run all of these tests.)
3. Each test should show “O” Fails. If any test shows fails, check to be sure the chip was installed correctly, and the system has been configured properly. If you are still experiencing problems, contact Cyrix customer support at the following number: (214)234-8387
