     pcibios_write_config_dword - write one double word  of  data
     to the configuration space of the PCI bus

SYNOPSIS

     #include <linux/bios32.h>

     int pcibios_write_config_dword (unsigned char bus,  unsigned
     char device_fn,unsigned char where, unsigned int value);

DESCRIPTION

     The pcibios_write_config_dword function  writes  one  double
     word to the configuration space of the PCI bus.  The bus can
     be  specified  with  the  bus  parameters.   The   device_fn
     paramter  determines which ? to use.  where is set to the ?.
     The word to be written to the configuration space is  stored
     in the value parameter.

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.

AVAILABILITY

     Linux 1.0?
