   No, I didn't know that, but I presume you mean in   
   protected mode.   
      
   I used to do INT 13H etc in protected mode, and it would   
   be translated into an INT 13H in real mode, but Alica changed   
   the code so that it has this:   
      
   #define BIOS_INT_OFFSET 0x90 /* BIOS interrupt 0x10 is moved to 0xA0. */   
      
   She also copied the real mode interrupt vectors to match.   
   I'm not sure if she considered the option of subtracting   
   0x90 from the interrupt number when it reached the   
   real mode code instead.   
      
   I would ask her if Microsoft's goons hadn't got to her first.
