pcibios_read_config_byte  - read one byte of data from the
       configuration 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  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 ?.  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_SUP­
       PORTED is returned.

AVAILABILITY

       Linux 1.0?
