(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.
When a cycle is detected on the hub interface, the ICH4 will positively decode the cycle. If the
response is on the behalf of an LPC device, ICH4 will forward the cycle to the LPC I/F.
Refer to
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. The ICH4 does not perform any
checks for conflicts.
