     The system includes a machine-independent PCI bus subsystem and several
     machine-independent PCI device drivers.

     Note that interrupt mappings on the i386 may require that you configure
     your BIOS to reserve sufficient interrupts as "PCI/ISAPnP" so that there
     are sufficient interrupts remaining to configure the discovered PCI
     devices.  For more information, see pcibios(4).

     OpenBSD provides support for the following devices.  Note that not all
     architectures support all devices.

     If the kernel is compiled with the USER_PCICONF kernel option, the
     following ioctl(2) calls are supported by the pci driver.	They are
     defined in the header file <sys/pciio.h>.

     PCIOCREAD	      This ioctl(2) reads the PCI configuration registers
		      specified by the passed-in pci_io structure.  The pci_io
		      structure consists of the following fields:

		      pi_sel	A pcisel structure which specifies the bus,
				slot and function the user would like to

		      pi_reg	The PCI configuration register the user would
				like to access.

		      pi_width	The width, in bytes, of the data the user
				would like to read.  This value can be only 4.

		      pi_data	The data returned by the kernel.

     PCIOCWRITE	      This ioctl(2) allows users to write to the PCI device
		      specified in the passed-in pci_io structure.  The pci_io
		      structure is described above.  The limitations on data
		      width described for reading registers, above, also apply
		      to writing PCI configuration registers.

     PCIOCGETROM      This ioctl(2) allows users to read the contents of the
		      PCI ROM specified in the passed-in pci_rom structure.
		      The pci_rom structure consists of the following fields:

		      pr_sel	 A pcisel structure which specifies the bus,
				 slot and function the user would like to

		      pr_romlen	 Size of the buffer to store the contents of
				 the ROM.  Upon return, this field will
				 contain the size of the ROM

		      pr_rom	 The address of the buffer to store the
				 contents of the ROM.

		      If the ROM is larger than the specified buffer size,
		      ENOMEM will be returned.

     /dev/pci*	Character device for the pci driver.
