Responding to: ???'s previous message
I have not found crutical modifications of registers
Oh, that old urban legend again

Not, that old urban legend again. A bootloader is there to load a program, not a partial program.
no bootloader (at least none I know) gives any guarantee about the content of registers or RAM after the run. A bootloader is supposed to load a program from scratch and what is the natural thing to do after that? a reset!. Thus the contents of registers and RAM is totally irrelevant.

If you suffer from the illusion that the '51 is a "mini PC" and want to load through a "monitor" then the loader is not a bootloader and should be located in user memory.
