Where does it fail? Can you dump the script?

Welcome to OpenBIOS v1.0 built on Aug 16 2009 18:47

load-base
begin
 dup 6 " </CHRP" $= if
  6 + dup 6 " -BOOT>" $= if
   8 + true
  else
   false
   then
 else
  1+ false
 then
until
( xcoff-base )
load-size over load-base - -
( xcoff-base xcoff-size )
load-base swap move
init-program go

The issue seems with "$=".
I think "init-program" and "go" are also missing.
"go" like "load" is needed by openSUSE script too.

There is also a "bug" in the try_chrp_script() procedure which loads the
script into the stack instead of at "load-base".

I'll work on these issues, but I'm not a Forth expert (I learn) ...
