hey people
this makes me mad: pointers use the DS selector, so if DS starts at 0xc0000000 then I can´t have a pointer to 0xb8000 unless i make it 0x400b8000. Perhaps it is better to have the kernel at 0x0 ? (in virtual addressing, of course)
Speak yourself and tell me how you handle the problem and where in memory do you put your kernel.

Use "flat mm" + virtual mem, paging.
