ExpressCard Configuration Submenu
Note
This submenu is available on the PXIe-8840 ExpressCard variant only.
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 is 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.
