Subject: [PATCH] Notify the small but important change in bootsect.asm. Since
 checkpoint, our kernel will be larger, so the number of sectors to read when

them of the change in 'bootsect.asm', they will encounter disk read
error in the later lessons.

 Furthermore, since from now on we will use mostly C to code, we'll take advantage of qemu's
 ability to open a connection to gdb. First, let's install a cross-compiled `gdb` since
