Setting the CPU Clock Speed This option lets you set the default speed at which your computer's processor operates when you turn it on: P High speed (20 MHz) 0 Low speed (10 MHz) Q Auto speed. When it is running at high speed, the TURBO light on the front panel is illuminated. At high speed, it can access memory faster, so your programs work faster. You should use high speed for everything you do unless you are using an application program that requires the slower speed. Some programs (especially older ones) have specific timing requirements when accessing diskettes. Check your application program manual. You can also set the processor to change speed automatically. This enables the computer to switch to low speed whenever it needs to access a diskette but run at high speed for all other operations. Select Hi gh speed for 20 MHz, Low speed for 10 MHz, or Auto speed to have the computer switch to low speed automatically when necessary. Note You may not want to use the automatic setting for certain copy-protected programs. See "Changing the Processor Speed" in Chapter 4 for more information. In addition to selecting the default operating speed through SETUP, you can change the speed temporarily by giving a keyboard command or by running the ESPEED program. See "Changing the Processor Speed" in Chapter 4 for more information. Running the SETUP Program 2-11
