Changing the Jumper Settings
The main system board in your computer has a number of
jumpers which control certain functions. These jumpers are
preset at the factory to default positions; however, you can alter
the following functions by changing the standard settings:
Enable or disable the built-in VGA display adapter
Set the computer to use a CGA or other type of display
adapter
Reset the CMOS RAM settings to the factory defaults
Enable or disable the PQFP (surface-mounted)
microprocessor on some 486SX/25 systems
Change the microprocessor type (if you upgrade your
system with a new microprocessor)
Change the processor speed.
If you need to change any jumper settings, or if you want to
check the current settings, follow the instructions in this section.
The following tables list the jumper settings and their functions.
