       space of the PCI bus

SYNOPSIS
       #include <linux/bios32.h>

       int  pcibios_read_config_byte  (unsigned	 char	bus,   unsigned	  char
       device_fn,unsigned char where, unsigned char * value);

DESCRIPTION
       The  pcibios_read_config_byte function reads one byte from the configu‐
       ration 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 ?.	 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.
