Expresscard Configuration Submenu; Usb Configuration Submenu - National Instruments PXI Series User Manual

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.

space, in bytes, that will be reserved by the BIOS for PCI-PCI bridges
that may be hot-plugged in the ExpressCard slot. The default value for
this setting is 64M bytes of memory.
Reserved I/O—This setting determines the amount of I/O space, in
bytes, that will be reserved by the BIOS for PCI-PCI bridges that may
be hot-plugged in the ExpressCard slot. The default value for this
setting is 4K bytes of I/O space.
USB Devices—This item lists the total number of devices detected in
