pcibios_write_config_byte  - write one byte of data to the
       configuration space of the PCI bus

SYNOPSIS

       #include <linux/bios32.h>

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

DESCRIPTION

       The  pcibios_write_config_byte function writes one byte 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
       byte 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_SUP­
       PORTED is returned.

AVAILABILITY

       Linux 1.0?
