pcibios_read_config_word - read a word of data from the con-
figuration space of the PCI bus
int pcibios_read_config_word (unsigned char bus, unsigned
char device_fn,unsigned char where, unsigned short * value);
The pcibios_read_config_word function reads a word from the
configuration space of the PCI bus. The bus can be speci-
fied with the bus parameters. The device_fn paramter deter-
mines which ? to use. where is set to the ?. After the
call is made, value points to the value that was read.
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
