PCI parity allows parity checking of data across the PCI bus. Some adapters do not generate parity and will require the PCI Parity option be set to Disabled. Bus mastering lets installed bus master PCI adapters process information without using the microprocessor. Enable bus master if your device or adapter must have the bus master function enabled when the computer is turned on. Some devices or adapters might not work properly if the bus master function is enabled when the system is restarted. Note: If PCI adapters do not operate properly, you might need to disable the PCI Bus Master option. The Plug and Play Control menu lets you change certain settings for Plug and Play devices. Set Device Node: When this option is disabled, programs will not be able to make changes to the power-on configuration. Address Decode: Most Plug and Play adapters use 16-bit address decoding. If you are experiencing problems with a Plug and Play adapter, changing the address decode setting to 10-bit might fix the problem. Plug and Play Operating System: Select Yes for this option if you are experiencing POST errors numbered 185x and your startup operating system is Plug and Play compliant. See your operating system documentation to determine if your operating system supports this function. This indicates what the speed is. Ensure that you set the correct speed. The Processor ID is displayed. Enabling or disabling Processor Updating determines whether the BIOS will apply microprocessor updates when the computer starts. 90 Using Your Personal Computer
