Memory Range
Software must not attempt locks to memory mapped I/O ranges for USB EHCI or High
Precision Event Timers. If attempted, the lock is not honored, which means potential
deadlock conditions may occur.
PCI is the target when the Boot BIOS Destination selection bit is low (Chipset Config
Registers:Offset 3401:bit 3). When PCI selected, the Firmware Hub Decode Enable bits
have no effect.
