Well, it seems to work here but it still doesn't look reliable enough to me. And this addon_zo thing of arbitrary 256K is strange. What we should do instead and IMHO is have a special setup_data section located right above .text where struct setup_data things are put in so that they never get overwritten. This should be the cleanest IMHO. It is hpa's call in the end of the day anyway. Thanks. -- Regards/Gruss, Boris.
