4.3.2 Variable I/O Decode Ranges
Tab l e 4- 3 shows the Variable I/O Decode Ranges. They are set using Base Address
Registers (BARs) or other configuration bits in the various PCI configuration spaces.
The PNP software (PCI or ACPI) can use their configuration mechanisms to set and
adjust these values.
Warning: The Variable I/O Ranges should not be set to conflict with the Fixed I/O Ranges.
Unpredictable results if the configuration software allows conflicts to occur. Intel®
Xeon® Processor D-1500 Product Family does not perform any checks for conflicts.
