INT 06 - CPU-generated (80286+) - INVALID OPCODE
Desc:   this interrupt is generated when the CPU attempts to execute an
          invalid opcode (most protected-mode instructions are considered
          invalid in real mode) or a BOUND, LDS, LES, or LIDT instruction
          which specifies a register rather than a memory address
Notes:  return address points to beginning of invalid instruction
        with proper programming, this interrupt may be used to emulate
          instructions which do not exist; many 386 BIOSes emulate the 80286
          undocumented LOADALL instruction which was removed from the 80386+
