I was wondering about XPostFacto, you say have install opendarwin with 
it?
And, is it that, that is what XpostFacto does, nothing else?  From the 
ads, I thought
it wrapped the installer...

if one could dump the open firmware before and after, I think there 
something posted
to the list to do that, I can't find it...

 From the post you reference, bootr  is from the system disk patches , 
does XpostFacto
include that image, and fix it so it works where it doesn't?, did they 
have to get rights
to use it? Or did they reverse-engineer it , and re-imp it? I mean, one 
could maybe try 'see bootr'... but perhaps one could just clobber the 
darwin, after corrrectly install, you say you did opendarwin , so it is 
not actually osx?

is it really this? or maybe "boot" is actually in the default column of 
printenv?
-- just that this really looks like a hodgepodge of forth syntax idioms.


Also from the referenced post:

This sounds , like a familiar problem with OF3 machines.
Try inserting 1 of:
" screen" output
s" screen" output
output-device output

It seems like apple doesn't like the output from OF, too PC like I 
guess, so the display
isn't turned on, until 'quit' in OF, which doesn't get called if it 
autoboots, leaving
whatever is booted to try to turn it on.  I found to completely get 
console I/O
in forth to work, I needed this:
  input-device input
  output-device output
  true to use-console?
