  	  Even if you say Y here, the currently visible virtual console
  	  (/dev/tty0) will still be used as the system console by default, but

  config PCI
  	bool "Support for PCI and PS/2 keyboard/mouse"
  	help
  	  Find out whether your system includes a PCI bus. PCI is the name of
  	  a bus system, i.e. the way the CPU talks to the other stuff inside
  	  your box.  If you say Y here, the kernel will include drivers and
  	  infrastructure code to support PCI bus devices.
  
  	  CONFIG_PCI is needed for all JavaStation's (including MrCoffee),
  	  CP-1200, JavaEngine-1, Corona, Red October, and Serengeti SGSC.
  	  All of these platforms are extremely obscure, so say N if unsure.

  	  Say Y here to include the GRPCI Host Bridge Driver. The GRPCI
  	  PCI host controller is typically found in GRLIB SPARC32/LEON
  	  systems. The driver has one property (all_pci_errors) controlled
  	  from the bootloader that makes the GRPCI to generate interrupts
  	  on detected PCI Parity and System errors.

  	  If you say Y, the OpenPROM device tree will be available as a
  	  virtual file system, which you can mount to /proc/openprom by "mount
  	  -t openpromfs none /proc/openprom".
  
  	  To compile the /proc/openprom support as a module, choose M here: the
  	  module will be called openpromfs.
  
  	  Only choose N if you know in advance that you will not need to modify
  	  OpenPROM settings on the running system.
