- │ SpeedTest Version 4.2 was designed to test the mathematical │
- │ capability of a computer system. The program code directly supports │
- │ a math coprocessor such as the INTEL 8087, 80287, and 80387. The │
- │ program will also support the INTEL i486 microprocessor, which has │
- │ an internal floating point unit superior to the 80387! │
- │ │
- │ You can force the program to ignore the math coprocessor by use │
- │ of an environment variable. This will show you how efficient the │
- │ coprocessor can be under ideal situations. At the DOS prompt type │
- │ SET NO87=OFF and hit ENTER. Run TESTV42.EXE and the program will │
- │ execute without the help of the coprocessor. Note the times! │
- │ │
- │ To use the coprocessor again, at the DOS prompt type SET NO87= │
- │ and hit ENTER. Please note that there is NOTHING after the `equals' │
- │ sign. Now run TESTV42.EXE again! There will be quite a significant │
- │ difference between the two if you DO have the math coprocessor!! │
- │ To make it easier, I have included TESTON and TESTOFF that will run │
- │ SpeedTest 4.2 with and without the coprocessor. │

- │ SpeedTest 4.2 was optimized for use with a math coprocessor. Most │
- │ programs are not, so depending on the application you use, you may │
- │ not see the difference in speed that SpeedTest 4.2 reflects! │
