I am trying to do a simple vga(320x200x256) driver but am having troubles
switching the video mode. I am using:
asm volatile("movb $0x00, %ah;");
asm volatile("movb $0x13, %al;");
asm volatile("int $0x10;");
which several websites and books are saying is all that is needed to
switch modes. However this locks up my machine. What am I doing wrong?
