Nah, here I rather distinguished "undocumented changes from MS-DOS 6 to 7" and the documented ones, which were like the config.txt user documentation describing some of the changes and giving away hints as to what changed technically ;-) (So, yes, you're probably right.) > It just happens that nobody has updated RBIL.

If the fnode really goes away soon, the code could be easily changed to use the fields in the SFT instead I guess. (Or not required, see other mail from Eric!)
