       pcibios_write_config_dword  - write one double word of data to the con‐
       figuration 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.
