: Why should an inplace copy be dangerous? Ok, for Jazz machines the kernel
: needs several *microseconds* longer to startup. A long time if you're
: in hurry :-)
In the past I've been bit by having inplace copy routines destroy what
was being copied.
: I definately bugged mem_init() for your machine which frees the complete
: low 640k including the exception handlers ... As paging_init() gets
: called before mem_init() this cannot be your problem. Hmmm...
I'll have to take a look at that. The last kernel I built is dying in
free_area_init, so I don't think your freeing the entire lower part of
memory is the problem either...
: Adjust the videoparams and you have a debugging console. Usage should
: be clear after a short look into the code. With print_string() and
: sprintf() in combination you can the same things as with printk().
: tinycon.c is also easily useable for other machines with a PC style
: character based display.
I'll have to whip that into shape, since I need to get the values of
things like the end of memory, etc. I'd rather not do the gdb
debugging yet, since I think that would be harder...
