Thanks Peter - I gave that a try but no luck. I am in the process of
writing some routines which will dump the contents of the registers
upon entering startup_32 and the relocation jump address prior to
the jump.

My assembler is a bit rusty, so it is taking a bit of time

What other information should I dump?
