Installation and Configuration
Power/Wake Configuration Submenu
Use this submenu to apply alternate configurations to the power and wake features of the chipset
and controller. Normally, you do not need to modify these settings, as the factory default settings
provide the most compatible and optimal configuration possible.
•

should return to after AC power is lost. Valid values are

ExpressCard Configuration Submenu
Use this submenu to apply alternate settings to the ExpressCard configuration. These settings
determine how much memory space, I/O space, and PCI bus numbers will be pre-allocated for
the ExpressCard port, allowing non-PCI Express-aware operating systems to support
hot-plugging ExpressCard devices. Normally, you do not need to modify these settings, as the
factory default settings provide the most compatible and optimal configuration possible.

Reserved I/O
to
0K
.
