Desktop tower system support multiple external I/O ports, expansion slots and
internal/external storage device. These configurable IO ports/slots can be
enabled/disabled via BIOS setup options.
It is not easy to understand the physical ports mapping if there’re many individual
USB ports. For expansion slots and SATA devices, although they have printing on
motherboard, user needs to open the cabinet to find the printing.
Once IO port/slot setup option has change, user needs to reboot system and check
IO port/slot enable/disable state in OS environment.
In order to help user to realize the physical IO ports mapping conveniently, BIOS
support adding or deleting device name behind corresponding IO port setup option
If the setting of IO port setup option is enabled, BIOS has ability to do PCI/USB bus
enumeration in BIOS setup menu to find out device information if hot plug IO device.
BIOS adds device name behind IO port setup option immediately when user plug in
IO device. But if user configure IO port setup option from enable to disable, BIOS
also delete device name from IO port setup option immediately.
