[SeaBIOS] Saving a few bytes across a reboot

    is it possible to save a few bytes, a pointer, across a reboot? I 
have tried to do this by allocating a memory chunk in the fsegement and 
storing the pointer there surrounded by 2 'magic' 32 bit values. When 
trying to find the magic values on reboot early in handle_post() it 
doesn't seem to find them anymore. Is there another memory segment where 
SeaBIOS could store the few bytes and find them again?
