Note: All of the setting names below may not be the exact word- ing on your system. This is due to the great number of Motherboard and hardware manufacturers. The settings may be listed on your system using different words that mean the same thing. Refer to your motherboards’ manual or contact the manu- facturer if you are unsure.

Perform the following steps to check for a Plug and Play Motherboard and to reset the configuration.

1.Reboot your computer.

2.When your computer is going through its POST (Power On Self Test) enter into your BIOS(Basic Input/Output System).

3.Some BIOS’s have a setting that will let you enable the Motherboard for Plug and Play. You should look for a setting that says “Plug and Play OS.” “Enable” this function.

4.The second setting to look for is under the heading “PNP/PCI Configuration.” Under

this heading check to make sure that “Resources Controlled By” is set to “Auto.”
