Now my kernel is working with GDT and IDT in pmode,
and I wrote a lot of code for video output routine,
then the first prob is
how can I get the position of current cursor? I tried
the ports 3d4h & 3d5h, but useless.
and the second, I feel that I can be get more free
time if I can use the old BIOS functions (vectors in
addr 000h-3ffh), any tips ?
