5323## integer `hw.pci.enable_io_modes`
5324Enable I/O and memory bits in the config register.  Some BIOSes do not enable these bits correctly.  We'd like to do this all the time, but there are some peripherals that this causes problems with.
5325
5326## integer `hw.pcic.pd6722_vsense`
5327Select CL-PD6722's VSENSE method.  VSENSE is used to determine the voltage of inserted cards.  The CL-PD6722 has two methods to determine the voltage of the card.  0 means assume a 5.0V card and do not check.  1 means use the same method that the CL-PD6710 uses (default).  2 means use the same method as the CL-PD6729.  2 is documented in the datasheet as being the correct way, but 1 seems to give better results on more laptops.
5328
5329## integer `hw.pcic.intr_mask`
5330Mask of allowable interrupts for this laptop.  The default is generally correct, but some laptops do not route all the IRQ pins to the bridge to save wires.  Sometimes you need a more restrictive mask because some of the hardware in your laptop may not have a driver so its IRQ might not be allocated.
