I use int 10h to set the video mode like this: union REGS regs; regs.w.ax=mode; int386(0x10,®s,®s); That works fine. (I know this because when I use printf, the letters are really big) But I can't get a pixel on the screen. I've tried unsigned char *scr=0xa000; with many different amounts of 0s after the a. But I always get a GPF. How can I write to the screen. (Any suggestions for setting the mode without bios would also be appreciated)
