Power Management Setup
As with other setup screens, the instructions governing choices in this environment can be found in the corresponding section in the motherboard manual. Use the feature settings found in Power Management Setup screen to control the optional power management for devices on the computer. These features can be enabled in order to control devices going into sleep or suspend mode. However, be aware that some software applications and operating systems may not deal well with components being powered down, as the software may no longer recognize such devices properly. In fact, it is usually recommended to disable the feature choice "Power Management".

PnP/PCI Configuration Setup
The PnP/PCI Configuration screen contains the feature settings used to control the system I/O bus and Interrupt Request (IRQ) and Direct Memory Access (DMA) allocation for ISA and PCI Plug and Play (PnP) devices. One feature of particular importance in this section is the "Resource Controlled By" setting. When set by default to Automatic Configuration, the BIOS will automatically manage the interrupts and direct memory access channels on the I/O bus for the PnP devices to avoid conflicts with any legacy (non-PnP) ISA devices. Note that sometimes IRQs or DMAs must be manually designated for some non-conforming PnP expansion boards or adapter cards. In such cases, such designated resources will have to be removed from BIOS handling.

In general, the default settings should be used for this section of the BIOS setup when working on newer systems because any manual configurations require a good knowledge of the bus devices installed. If any conflicts occur, be aware that the "Reset Configuration Data" feature will clear this portion of the BIOS setup and return it to defaults upon rebooting the system. Additionally, consult the system board manual before making any changes here.
