Okay so there's your first issue in 0xa08 - the PCI config words 
config-*@ and config-*! aren't (yet) implemented in Forth in OpenBIOS so 
you'll need to wrap the existing pci_config_read/pci_config_write() 
functions using something similar to the approach here:

https://github.com/openbios/openbios/commit/74ee111f1ff64415835c4c43b66b1528a85fac9c

Here you can see that the C function bind_func() to used to call a C 
function from Forth by binding it to the named Forth word in the dictionary.


ATB,

Mark.
