I assume you are going to debug kernel, for GNU/ Linux is not 'real mode'
only. User space programme runs in protected mode whereas kernel in real mode
( So far as I known). To debug kernel, there are several options you can
choose, including kprobe, kgdb and kdb. Each has their own advantage. You can
have a look it online.

: GDB似乎無法run real mode program
: 目前我都只能用VirtualBox看程式跑出來的結果對不對
