Variable I/O Address Ranges
shows the variable I/O decode ranges. These blocks are independently
configured and enabled by the platform BIOS. They are set using base address
registers (BARs) or other similar means. Plug-and-Play (PnP) software (PCI/ACPI) uses
their configuration mechanisms to set and adjust these values.
Warning:
The variable I/O ranges are not set to conflict with other I/O ranges. Unpredictable
results can happen if the configuration software allows conflicts to occur. The hardware
does not check for conflicts.
