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?

Graeme
