Running the Landmark System Speed Test 

To compare the performance increase provided by PowerLeap™, we suggest running the 
Landmark System Speed Test® both before and after installation of the processor 
upgrade. The Landmark System Speed Test® is provided on the software distribution 
floppy disk. 

The Landmark rating measures the speed of the processor at performing calculation 
tasks. Run the Landmark System Speed Test® as follows: 

Insert the software distribution floppy disk into drive A. 

At the DOS prompt, type 

SPEED200

 [

switches

] and then press <Enter>. The optional 

switches are described below. 

 

Running the Landmark System Speed Test® from within Microsoft 
Windows or OS/2 may yield unreliable results. For best results, run 
the test program from the DOS prompt. Do not run the test program 
from a DOS task within Microsoft Windows or OS/2. 

Test Switches 

You can run the Landmark System Speed Test® with the following optional switches:
