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.
