Thanks
Thats what I tried with elf kernels (both SMP an single CPU ones) but I
get a:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x36719cc7
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf0126294
stack pointer = 0x10:f0291f84
frame pointer = 0x10:f0291f98
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 0 ()
interrupt mask = net tty bio cam
kernel: type 12 trap, code=0
Stopped at 0xf0126294: movl 0(%esi),%ecx
db>
This happens after it starts loading the kernel.
