DESCRIPTION

     The pcibios_read_config_word function reads a word from  the
     configuration  space  of the PCI bus.  The bus can be speci-
     fied with the bus parameters.  The device_fn paramter deter-
     mines  which  ?  to  use.  where is set to the ?.  After the
     call is made, value points to the value that was read.

RETURN VALUE

     The return value is taken from the PCI controller in  a  way
     that I'm not quite sure of.

     If the PCI system is unavailable, PCIBIOS_FUNC_NOT_SUPPORTED
     is returned.
